The production of dry mixes for construction purposes can become a stable source of income that does not depend on seasonality. The business does not require large investments. All investments in it quickly pay off, since the entrepreneur does not have problems with the sale of products. It is in demand not only by private consumers, but also by business entities specializing in the sale of building materials. What is needed to conduct production activities and what should be paid attention to when organizing it?

Dry mixes

general information

Any type of construction work is associated with the use of mixtures of special materials. Their use is economically justified and convenient from a practical point of view. Dry building mixtures are in the form of powdery and bulk materials, which, when mixed with a liquid, form various solutions. Depending on the characteristics of the feedstock, they may have different properties. The compositions are used for waterproofing, gluing, puttying, plastering or for installation.

The raw material does not need much space to store, because it is characterized by compactness. To prepare working compositions, it is enough to dilute it with water. The work carried out with their help is carried out quickly and is of high quality. Depending on the construction task, mixtures of various formulations are used. The quality of the prepared solution depends on their composition. Its performance is identified after processing and maintaining the necessary time to stabilize or to solidify the composition.

Business Relevance

The growth in the pace of construction work and the use of modern technologies for their provision determines the demand for dry mixes, since the preparation of the compositions takes a minimum of time, and their characteristics correspond to the required parameters.

These factors determine the demand for the product, which has become the reason for the prospects and profitability of the business for its production. The use of dry mixes in construction greatly simplifies the task of builders. They get the opportunity to work with working solutions, the characteristics of which are ideally suited for a particular type of activity. And for their manufacture it is not necessary to create special conditions. The mixture is enough to place in a container, pour water into it and mix thoroughly until smooth. All components are taken in accordance with a certain proportionality.

Production scheme

Ready-made solutions cannot be stored for a long time, in addition, large containers and a territory of the corresponding area are required for their placement. Compositions from dry mixes are prepared in the amount necessary to ensure a specific job. They are not subject to storage, as they must be fully used. Placing powders does not require much space. Their storage is limited only by the period of use of the product. The only condition for maintaining the original properties of the mixture and for preventing lumping is to ensure dryness in the premises.

Product range

When compiling a business plan, you should analyze in advance the demand for the product planned for production and draw up its assortment range, on the basis of which further operations will be planned.

Today, adhesive mixtures for laying tiles and for processing the facade are popular. There will quickly be buyers for self-leveling floors and for cement screed. Specific, but no less popular products are assembly mixtures, compositions for gypsum plaster, for waterproofing and for all types of putties.

Where to look for buyers of products?

When planning the production of dry building mixes, one should focus not only on retail consumers, but also on buyers who would make bulk purchases. These categories include companies specializing in the provision of repair and construction work. Since their activities are directly related to the purchase of quality materials, the manufacturer should be offered cooperation on favorable terms. The slightly reduced price of the product will be offset by the lack of advertising campaigns and customer searches.

Stores and building bases can become regular wholesale buyers. To attract them to partnerships, it is recommended to send letters with a business proposal for cooperation. After a while after sending them, it is recommended to call the enterprises in order to remind about yourself and conduct personal negotiations with the management about possible deliveries at competitive prices.

An additional source of income will be sales through the online store. Its buyers will be individuals and business entities that have access to worldwide networks and know the nuances of making purchases via the Internet.

The production of all building mixtures is carried out according to a single algorithm. It includes operations such as:

• preparation of constituent components;
• transshipment of raw materials;
• placement of raw materials in bunkers;
• dosing of initial components;
• mixing;
• package;
• warehousing.

The technology of the process provides for preliminary drying of raw materials, for which it is loaded into a drying drum. As the particles dry, they are poured onto a vibrating sieve. The apparatus is designed to separate the constituent elements into fractions.

Schematic representation of the technological line

Only coarse sand is used in production. The process automatically stops when the auger is filled with the required amount. After loading the sand into the storage bin, it is fed in small portions into the cement bin, into which additional substances are added to ensure certain characteristics of the finished product. The resulting mixture is mixed and fed into the packing hopper for packaging in paper bags.

To improve the quality of the finished product and simplify the packaging process, it is possible to purchase additional equipment that provides fluidization of bulk materials, as a result of which they acquire the consistency of a pseudo-liquid. Packaged products are shipped to the warehouse or delivered to the consumer.

Nuances of automation

The production process is automated. Participation of employees in it is minimal, which saves money on wages. Operations are controlled by a technologist who sets up the appropriate mode in the software of the technological line for the production of a mixture according to a specific recipe. After starting the line, each component is automatically weighed, which are loaded into the mixer one by one.

Completion of each production stage is accompanied by a light signal displayed on the display of the equipment. The production line operator controls all operations and gives permission, at the request of the system, to continue the production process.

The need for an additional structural unit

Appearance of the production line

In order for the finished product to meet the requirements of regulatory documentation and the parameters declared by the manufacturer, the entrepreneur should provide for laboratory studies of the quality of raw materials and ready-made dry mixes. Permanent laboratory studies of samples of materials will cost the entrepreneur a lot, therefore it is recommended to include a laboratory assistant in the staff, as well as purchase the equipment and reagents necessary for the analysis.

What additives are used

The main components of all building mixtures are cement and sand.

Depending on the characteristics of the final product, a different ratio is taken. To improve the qualities of the composition and to give it the properties necessary to ensure the performance of the relevant types of construction work, various additives are used.

To use the mixture for laying tiles or for self-leveling floors, it is necessary to add surfactants to it, which give plasticity. Hydrophilizing surfactants prevent particles from sticking together, resulting in thick solutions with a minimum amount of solvent, which will facilitate the use of the finished composition. Since this type of additive helps to slow down the hardening, they are combined with hardening accelerators.

The development of building technologies has led to the fact that any work in this area is carried out using building mixtures prepared for a certain type of work. Separately for wall cladding, their construction, decoration and more. As practice shows, such differentiation improves the quality of work and their efficiency. Therefore, dry building mixes are always in demand during construction work.

Benefits of using dry mixes

In short, the main advantages of using dry mixes are:

1. Significant savings in time and space. There is no need to waste time on the manufacture of dry mixes for certain jobs, to store the components at the construction site.
2. Each manufacturer can produce a mixture of any complexity according to individual customer requests.
3. The material is prepared exactly in the amount that is necessary for a given amount of work. This eliminates the loss of raw materials.
4. Savings on logistics costs - no need to constantly bring a new solution and worry about its quality during transportation.
5. Mixtures are of high quality, as the technology of their manufacture allows you to strictly adhere to the established recipe.

Types of dry mixes

Before you start a business, you need to understand it a little. In particular, to study what types of dry mixes are and which of them are most in demand on the market. As already mentioned, the recipe depends on the type of work in which the mixture will be used. Also, the composition of the components varies depending on the requirements for resistance to temperature changes, humidity, strength and other parameters.

The composition of dry mixes includes the following four main components:

• mineral binders;
• special additives (usually to retain moisture);
• inert fillers;
• polymer binders.

Classification of dry mixes is carried out on the basis of:

• type of binder filler (with and without cement);
• its dispersion (having coarse grain, up to 2.5 mm or fine grain, up to 0.315 mm);
• product destination.

How to build a business

You need to develop your business by producing the most popular mixtures in your area. It is worthwhile to study in advance what construction work is being carried out in your region, what type of dry mixes is most in demand, and its required volumes. But as a general rule, the most popular is such material:

• gypsum plasters;
• assembly mixes;
• various putties;
• compositions for self-leveling floors;
• waterproofing mixtures;
• compositions for cement screed;
• various kinds of various adhesives (wallpaper, tiled, facade).

Composition of the mixture

The components of any mixture are the following three main components:

• astringents;
• fillers;
• functional additives.

The characteristics of the final mixture depend on what specific raw material is taken, what proportions are used. The exact recipe is usually developed by each manufacturer separately and kept secret.

Of the binders are usually used:

• minerals - gypsum, lime, cement (aluminum, silicate);
• organic derivatives - cellulose ethers that dissolve in water, polymer powder;
• organo-mineral complexes - polymer silicate and polymer cement.

Of the fillers, slag, ash, dolomite, quartz, limestone, marble or stone waste are used.

Functional additives are used depending on the characteristics of the mixture to be achieved. Additives can give it special strength, increase the drying rate, the degree of thickening, moisture resistance, and so on.

Production technology

In short, the technology for the production of dry mixes goes through the following stages:

• preparation and transshipment of components;
• sifting components;
• loading material into feed bins;
• dosage of raw materials;
• mixing;
• packing;
• storage.

Frankly speaking, the production technology, despite the variability of the final material, has remained the same. The basis of such material is sand and cement. First, the sand is poured into the dryer drum. There it periodically scrolls and, as it dries, it pours out onto a vibrating sieve. Here it is screened by fractions: fine, medium and coarse sand.

As the auger accumulates sand of the desired fraction, the automated equipment stops. The sand is loaded into the storage bin, the forklift takes it to the storage cement bin, where all the necessary additional substances are added. The technology involves full automation of production, so the output material is of high quality. After thorough mixing, the system transfers the mixture to the packing hopper and packs it into special paper bags. This completes the mixture production technology. The material is stored for storage or transported to the customer.

room

The technological process is simple if you work with special equipment. The market offers a lot of production lines of various configurations. But it is better to decide on them in advance, since the requirements for the premises that are included in the business plan depend on this.

If you are building a business from scratch, you can purchase a minimum kit that will take approximately 50 square meters. m and will require rooms with ceilings 7 m high. A mid-range business will require an area of ​​​​at least 120 square meters. m., of which approximately 50 sq. m is allocated for a warehouse, and the rest - for equipment.

The plan for repairing the premises should include the installation of a good exhaust, as well as heating, so that the temperature in the room is maintained at a level of approximately 16-18 ° C.

Equipment for the production of building mixtures

One of the main issues that your business plan should solve is the purchase of equipment. As a rule, a fully equipped production line is immediately purchased. It includes:

• mixer;
• auger and packing hopper;
• lift;
• dispenser;
• sand dryer;
• work site;
• vibrating sieve;
• auger automatic.

Separately, the purchase plan should include euro pallets, tools, commodity and electronic scales.

How much money to include in the cost plan for such a line depends on its configuration and functionality. For example, a line with a capacity of 5 tons of mixture per hour will cost 1.6 million rubles. But on it the packaging stage is carried out in a semi-automatic mode. When buying a line with a capacity of 10 tons, its price will also double.

Raw material

Without fail, the business plan includes the cost of purchasing raw materials and paying staff. Of the raw materials, the modifying additives will be the most expensive. In addition to them, it is necessary to purchase hydrated lime, calcium carbonate, quartz sand, gray and white Portland cement. The cost plan for raw materials must be calculated based on the cost of 10-170 rubles. per kilogram of each component.

Few raw materials are produced in our country. If we are talking about expensive additives, then they are not produced at all. The material will have to be purchased abroad, where the production of such raw materials has been going on for more than a decade. But in any case, the technologist must check each batch for the required properties. In addition, it is desirable to require from the supplier a certificate of conformity for each of the components. You will need them to issue the appropriate certificate for the final product.

Production staff

If you plan to work in one shift, it will require the following number of personnel:

• dosing and mixing station worker;
• loader;
• packer;
• master technologist.

The work of a technologist is the most expensive, as he develops the composition of mixtures, on which your business will mainly depend. He also decides which suppliers to work with depending on the quality of raw materials they offer.

Sales of finished products

Before you start working on an order, you need to develop a client base. To do this, it is necessary at the initial stage to work closely on its formation and search for distribution channels.

A sales plan can be formed based on the following distribution channels:

• specialized online stores;
• Retail Stores;
• markets;
• construction companies;
• intermediaries.

At first, the equipment will operate at about 50% capacity so that the goods do not stale, since it will be difficult to make a sales plan right away. In addition, due to the high competition in the market, it will not be easy to enter it. Please note that it is not economically viable to transport mixtures further than 300 km from the place of production. Therefore, you need to focus on your region.

As practice shows, from about the third month of the enterprise's operation, the production plan can be increased to 12 tons per shift. But such productivity can be achieved if we offer a wide range of products and produce each of the items in the shortest possible time. Of course, without sacrificing quality and price.

The sale of goods has some seasonality. Since construction and repair work subsides from November to March, interest in products also drops noticeably.

Business formalities

The business needs to be legally registered. It is advisable to dwell on such a form of organization as an LLC. In this case, you will be able to take large orders from enterprises that usually work only with legal entities.

For the operation of the workshop, the premises must be brought into line with the standards of the fire inspection and the sanitary and epidemiological service. After checking for compliance, they will issue you special certificates.

Product certification

Today, the law does not require mandatory certification of this type of product. To receive it or not is voluntary. But if you plan to participate in tenders of large organizations, you simply need such a document. There are two ways out of this situation.

You can issue a rejection letter for the goods. This is a document that confirms that this type of product is not subject to certification in accordance with the current regulations. But according to market operators, when participating in tenders, preference is given to those who have such certificates.

To issue a certificate of conformity or not, the entrepreneur decides. But keep in mind that this is an additional cost item.

economic calculation

The expenditure part consists of the following items:

• rent of premises - from 18 thousand rubles. per month;
• production line - from 1.6 million rubles;
• logistics - from 200 thousand rubles;
• purchase of raw materials - 400 thousand rubles. (for two months of work);
• wages and other expenses - 100 thousand rubles.

In total, to launch a production line with a capacity of about 12 tons of products per shift, approximately 2.5 million rubles will be required.

The cost of a bag of dry mix weighing 25 kg is about 60 rubles. 480 such bags can be made per shift. That is, you can produce products worth 22 thousand rubles per day. To this amount must be added 4 thousand rubles. production costs. That is, 26 thousand rubles will be required per day. for the production of goods. The cost of a bag is an average of 160 rubles. This means that 72 thousand rubles can be earned per day for 480 bags.

As practice shows, the profitability of such production is kept at the level of 150%. With active work to find distribution channels, you can return investments in 3-4 months. On average, the payback period is kept at the level of six months.

Dry building mixtures are very widely used in the construction of the buildings themselves, and also, this type of aggregate state is optimal for interior and exterior finishing materials. The dry mix is ​​very convenient for delivery, going through all stages of the sale, and using it directly for its intended purpose. They are ready for use, it is only necessary to add the prescribed amount of water and mortar before use, and it turns into a finished material.

The production of building mixtures begins with a mining enterprise. With the help of them, the necessary components are extracted from the deposits, and it is they that will be used further as raw materials.

Equipment for the production of building mixtures

To organize the production of building mixtures, it is necessary to have a whole variety of crushing machines that can progressively make the necessary powder from large blocks of the delivered mineral. Crushing machines are selected individually for each manufacturing technology. Manufacturers of such machines will not only be able to offer the most suitable ones, but will also be able to choose conveyor lines. They are an important element for the rapid flow of the production process.

List of the main equipment for the production of building mixtures:

• Mixer;
• Packing hopper and auger;
• Drying for sand;
• Vibrating screen for screening;
• Electronic scales;
• Commodity scales.

Dry mix production technology + video

Standard building mixtures usually consist of the following two components:

• Cement;
• Sand.

Their shares vary based on the brand of cement and the desired brand of the finished product - usually M150 or M200.

If you add surfactants (surfactants) to this list, then such a mixture can already be used for flooring or tiling. Surfactants make the finished solution more plastic.

Surfactants are able to increase the surface tension at the phase interface, for example, at the phase-solid, water-air interfaces. The smallest surfactant particles are adsorbed, in other words, they bind firmly to the internal interface of the bodies, forming on these surfaces molecular layers with a thickness of one molecule.

Video how building mixtures are made at a mini-factory:

The size of this adsorption layer is related to the diameter of the cement particle, just as the thickness of a matchstick is related to the height of a 30-story building. However, the use of small doses of surfactant additives to cement systems significantly changes their properties. The surface-active additives used in the production of building mixtures, according to the determining effect on cement systems, can be conditionally divided into three groups:

• Hydrophilizing;
• Hydrophobic;
• Air-entraining.

Hydrophilizing additives when mixed with water, the binder is capable of preventing the adhesion of individual cement particles to each other for a certain period. In this case, the coagulation of neoplasms somewhat slows down, that is, at the same time, a certain amount of water is released, which, as it were, usually gets stuck in the coagulation structures. For this reason, the required workability of a building mixture with an additive is achieved with a smaller amount of mixing water than without an additive.

The most widely used in the practice of preparing cement concretes and mortars are hydrophilic additives based on lignosulfates-sulfite-yeast mash (SDB). It is able to somewhat slow down the hardening of concrete at an early age, and therefore it is used in reinforced concrete factories in combination with additives that harden accelerators of building mixtures.

Superplasticizers - new effective thinners of the concrete mixture - in most cases are synthetic polymers - derivatives of melamine resin or naphthalenesulfonic acid. Superplasticizer S-3 (NIIZhB) is used - based on naphthalene sulfonic acid, superplasticizer 10-03 (VNIIZhelezobeton) - a condensation product of sulfonated melamine with formaldehyde, etc. When a superplasticizer is introduced into the concrete mixture, its mobility and fluidity sharply increase.

Influencing the building mixture, as a rule, within 2–3 hours from the moment of introduction, superplasticizers undergo partial destruction under the action of an alkaline environment and pass into other substances that are harmless to concrete and do not inhibit the hardening process. Superplasticizers, introduced into the building mixture in an amount of 0.15 ... 1.2% by weight of cement, dilute the building mixture to a greater extent than conventional plasticizers. The plasticizing effect persists, as a rule, 1-2 hours after the introduction of surfactants, and after 2-3 hours it is already small.

Superplasticizers are used in the production of building mixtures both alone and in combination with other additives, such as sulfite-yeast mash (SDB) and calcium nitrite-nitrate-chloride (NNCC). When using a complex additive, the content of each of them is: "10-03" - 0.3-1.2%; NNHK - 1.5 ... 2.5% and SDB - 0.1 ... 1.15% of the mass of cement.

Superplasticizers can significantly reduce the W/C, increase the mobility of the solution, produce high-strength products saturated with reinforcement from isoplastic building mixtures.

Hydrophobic additives, as a rule, significantly increase the non-separation, the cohesion of the concrete (mortar) mixture at rest. Under the action of external mechanical factors (during mixing, laying, etc.), a concrete or mortar mortar with an additive is characterized by increased plasticity. This property of hydrophobic building mixtures is explained by the specific lubricating effect of the thinnest layers of surface-active substances distributed in the solution.

In addition, these additives protect cements from rapid loss of activity during transportation or storage. In the past, mainly natural products were used as hydrophobic surfactants - some animal fats, aleic and stearic acids. The development of the chemical industry has made it possible to widely use new water-repellent additives in production - bituminous dispersions (emulsions and emulsifications), naphthenic acids and their salts, oxidized, synthetic fatty acids and their bottoms, organosilicon polymers, etc.

Air-entraining additives allow to receive concrete (mortar) mixes with some additional amount of air. To increase the plasticity of the building mixture, the volume of the binder dough is usually increased. By entraining air, the volume of the binder dough increases without introducing excess cement. Therefore, the workability of such a system is increased.

In addition, air-entraining surfactants also form oriented layers that are active in terms of lubricity. Air-entraining additives based on resin acids are widely used: neutralized air-entraining resin (SNV), saponified wood pitch, etc.

Cement hardening accelerators that increase the increase in concrete strength, especially in the early stages, include calcium chloride, sodium sulfate, nitrite-nitrate-calcium chloride, etc.

The effect of calcium chloride on increasing the strength of concrete is explained by its catalytic effect on the hydration of C3S and C2S, as well as its reaction with C3A and C4AF. Hardening accelerators are not recommended for use in reinforced concrete structures and prestressed products with a reinforcement diameter of less than 5 mm and for autoclave hardening products operated in an environment with a humidity of more than 60%. Sodium sulfate can cause efflorescence on products.

In nitrite-nitrate-calcium chloride, the accelerating effect of chloride is combined with the inhibitory effect of calcium nitrate. Antifreeze additives - potash, sodium chloride, calcium chloride and others - lower the freezing point of water, which contributes to the hardening of concrete at low temperatures. To slow down the setting, sugar syrup and SDB, GKZH-10 and GKZH-94 are used.

Foam and gas formers are used for the manufacture of cellular concrete. Foaming agents include glue-canifol, resin-saponin, aluminosulfonaphthene additives, as well as foaming agent GK. Aluminum powder PAK-3 and PAK-4 are used as blowing agents.

Combined surfactants, such as SDB plasticizer, hardening accelerator (calcium chloride) with an inhibitor (sodium nitrate), help to save cement. At the same time, the hardening accelerator neutralizes some slowdown in the hardening of the finished building mixture at an early age.

Special additives ensure the production of waterproof mortars or concretes, regulate the setting time, etc.

During the preparation of concrete building mixtures, the following types of chemical surfactants are added, which can improve the characteristics of future concrete and at the same time reduce the consumption of cement during production:

1. Individual - surfactants, electrolytes, polymer resins and others.
2. Complex - surfactants (SDB + GKZh-94, SDB + STRN and others), complex electrolytes of the following compounds (NNK + NNHK).
3. Complex - surfactants and electrolytes (SDB + Na2SO4; SDB + NNHC, SDB + Na2SO4; SDB + NaNO3 and others).

Surfactants are also used quite widely in the form of plasticizing additives, which allow not only saving cement, but also intensifying the hardening process. Also, due to the use of plasticizers, it is possible to reduce energy consumption in the preparation of concrete mixtures. The use of surfactants in rational, and strictly dosed quantities, can reduce energy costs during the preparation of concrete mixes by up to 50 percent.

Superplasticizers S-3, NIL-10, S-4.10-03, KMB and others are widely used in the production of building mixtures along with other types of additives. The use of such plasticizers makes it possible to increase the strength of concrete by a lot, reduce the water demand of the concrete mass without reducing mobility and workability. The use of superplasticizer 10-03 showed that the increase in the mobility of the concrete mix occurs 7 times.

With a decrease in the proportion of cement and when using the same plasticizer 10-03, the water demand of the concrete mass is halved. The strength of the concrete mass, while after daily hardening increases to about 70 percent, and with heat treatment up to 20 percent.

Superplasticizers are prepared on the basis of melamine-formaldehyde resins. Also based on condensation products of naphthalenesulfonic acid, formaldehyde, modified with lignosulfonates. Along with these superplasticizers, cheaper plasticizers are actively used in concrete production enterprises.

In particular, in the role of surfactants, cheaper calcium chloride is widely used in building mixtures as a hardening accelerator of binders. But such a plasticizer causes corrosion of steel reinforcement and reduces the resistance of concrete (cement stone) in a sulfate environment. Therefore, the use of such additives in concrete is limited.

Sodium sulfate is mainly used in the heat and moisture treatment of concrete. The use of sodium sulfate reduces cement consumption by up to 10 percent, and the time of heat and moisture treatment of concrete is also reduced, the processing cycle can be reduced from 20 to 30 percent.

Sodium nitrate is also used mainly in the heat-moist treatment of the building mixture. The use of sodium nitrate together with the SDB plasticizer reduces the steaming time to 25%, and the cement consumption is reduced to 14%. To increase the permeability of concrete, calcium nitrate is added to the concrete.

Complex additives mainly affect such important characteristics of the building mixture as the growth rate of the strength of the future concrete, mobility, setting time, shrinkage, frost resistance, corrosion resistance and others.

The use of complex additives in the building mixture is mainly caused by the need to reduce corrosion of steel reinforcement, shrinkage, as well as the possibility of increasing strength. The introduction of a complex of salts such as CaCl2 + NaNO2 makes it possible to almost completely eliminate the corrosion of steel reinforcement. Corrosion of reinforcement in concrete occurs due to aggressive chlorine ions, which are regulated by CaCl2+NaNO2 salts. To increase the strength, calcium chloride is added to the building mixture.

The use of Na2SO4 (from 0.8 to 1.2%) together with SDB (0.15 ... 0.2%) when using cassette technology significantly reduces the consumption of cement - from 8 to 10 percent. Saving cement and reducing the time spent on steaming concrete products also allows SDB + NaOH. The effect of cement consumption on the strength of steamed concrete with additives: KCl + (0.5 + 1.2)% Na2SO4 and Na2S2O3 + (0.7 + 1)% Na2SO4 and others is shown in Table-1.

Table 1. Influence of the type and amount of complex additives on the consumption of cement

They allow reducing cement consumption from 350 to 298 kg/m³, i.e. saving up to 15% of the binder while maintaining the tempering and brand strength of concrete. Due to the limited supply of electrolytes to the construction industry, their use in combination with surfactants is of great importance. At the same time, the efficiency of chemical additives sharply increases, the required amount of electrolytes is reduced by 3–6 times.

When using calcium nitrite-nitrate-chloride (NCCC) in an amount of 2...3% by weight of cement, the specified mobility of the concrete mixture is achieved at a lower (by 6.1...6.5%) cement consumption. When using 0.5% NNHK, there is no plasticizing effect. The use of a complex additive of SDB and 0.5% NNKhK has a strong plasticizing effect and allows not only to reduce cement consumption by 10%, but also to reduce the stiffness of the mixture from 19 to 10 s.

The introduction of surfactants and NNKhK improves the technological properties of concrete. With the introduction of complex additives into concrete (with a corresponding reduction in cement consumption by 9 ... 12%), concrete with F 500 ... F 1000 is obtained, which increases the service life of structures. The limiting amount of plasticizing additives in terms of dry matter is given in table-2.

• START, SPD, TsINPS 1-0.005…0.025;
• KM, BS, GK, SMPN-0.05 ... 0.15;
• GKZH-94-0.06…0.08 (consumption is based on dry matter).

The construction industry is an attractive niche for all those who have decided to organize their own profitable business. And here it is not at all necessary to start the production of high-tech components and structures - in order to attract decent profits, it will be enough to establish the work of a mini-workshop for the manufacture of material in demand on the market. Let's take dry building mixes (CCC) here. If you buy equipment for the production of dry building mixes, arrange wholesale supplies of raw materials and hire workers, you can recoup all costs in a short time. Dry building mixes are bulk materials widely used in the construction and repair of structures.

Our business valuation:

Starting investments - from 1,000,000 rubles.

Market saturation is average.

The complexity of starting a business is 6/10.

The idea is simple. But even with this in mind, in order to launch a mini plant for the production of dry building mixtures in Russia, it does not hurt to draw up a detailed business plan, which would reveal all the nuances of the future enterprise. And special attention here should be paid not even to technology, but to marketing strategies. After all, the success of the plant will depend on how well thought out the sales channels and ways of their development are.

How promising is the business?

According to experts, the market for dry building mixes tends to develop. And the growth of this segment will only increase, as the needs of the population are increasing, and SSS is now used in literally every area of ​​construction and finishing - plastering, puttying, surface decoration, cladding.

In many ways, the prospects of the business for the production of building mixtures are explained precisely by the demand for products - the sales market is simply huge.

The features of the technology and the materials themselves are such that it is possible to produce a variety of types of finished products using the same equipment. The main thing is to preliminarily conduct marketing research in order to understand what kind of material is in demand among the population in a particular region. It turns out that the range of manufactured products at minimal cost of raw materials can be quite impressive.

A particular advantage in organizing a business in this direction is the fact that the manufacture of dry building mixes is very simple in terms of technology. Therefore, in this case, it is possible to organize a workshop literally at home, where the final product is obtained by hand.

If we talk about the shortcomings of this direction, then it is worth noting the rather high competition in the market and the seasonal nature of the business. But these difficulties are quite surmountable if you produce a high-quality product and debug wholesale distribution channels.

What assortment to offer consumers?

The sale of dry building mixes will be profitable even in the off-season, when the entrepreneur will offer customers a wide range of finished products. And since the equipment is multifunctional, the business organizer has the opportunity to offer customers a variety of classes of goods.

What are the options here?

• facade and tile adhesives,
• mixtures for cement screed,
• mixtures for self-leveling floors,
• putties,
• plasters,
• waterproofing compounds,
• assembly mixes.

If you believe the statistics, then today the most popular materials of all are adhesives. It is them who are swept off the shelves of hardware stores in the shortest possible time. With this in mind, aspiring entrepreneurs can be advised to start their own business with the production of facade and tile adhesives. In addition, the technological process of their manufacture is the simplest and most inexpensive of all others.

It is worth considering in advance what kind of container dry building mixtures will be packed in, since for many consumers this is a matter of paramount importance. And the point here, of course, is not in the design of the package, but in its volume - it is more convenient for someone to buy in large bags, and for someone a small bucket of building mixture is enough. And in order to interest literally every client, it is important to diversify the products not only in appearance, but also in the way of packaging.

Description of the process of manufacturing dry building mixtures

Technological scheme for the production of dry building mixtures

A building mix plant can process a variety of raw materials - it all depends on the planned plan for the production of certain products. But despite the different composition ratio, the basis of the mixture is always the same:

• Astringent components (cement, clay, gypsum, lime).
• Fillers (crushed stone, quartz, (sand), marble, ash, slag, screenings, stone waste).
• Functional (additives) (starch ether, methylcellulose).

And even before purchasing the necessary equipment, it is necessary to carefully work out the recipe, since not a single operating enterprise will open it. Without certain knowledge in this area, it would be better to use the services of a qualified technologist who would not only develop the recipe, but also further monitor the observance of technological regimes during the operation of the line.

In general, the technology for the production of dry building mixtures may look like this:

• Preparation of the components required by the recipe (sifting and weighing).
• Mixing components in a certain proportion.
• Packing and packaging of the mixture.
• Storage of finished material.

And for each designated production stage, the appropriate machines are selected. There is also a more convenient option - a line already equipped and ready for work.

It is quite clear that the technology for the manufacture of dry material is extremely simple. And therefore, many operations here can be performed manually - only the sale of large wholesale cannot be established here. In order to sell dry cement building mixes in more impressive batches, you will need to equip your workshop with special machines and apparatus that will greatly simplify and speed up the process.

Technical equipment of the workshop

There should be no problems with equipping the workshop - there are a lot of offers from suppliers. A variety of equipment is presented here to the attention of entrepreneurs: automatic and mechanical, low-power and high-performance, fully equipped and separately.

And given that the mixers and the filling machine are of the same design, the choice in favor of one or another line must be made based on other considerations, in addition to the principle of their operation:

• planned sales volumes,
• available finances,
• manufacturer brand,
• conditions of the seller (service and warranty service, commissioning).

As practice shows, a line for the production of dry building mixtures with a capacity of up to 5 t / h will be quite sufficient for a young workshop. This will be equipped with all the machines necessary for operation, and its cost will not exceed 1,600,000 rubles. It is also good that the mini-installation does not take up much space - a maximum of 50 m 2.

For those who are on a tight budget, it may be advisable to purchase each unit separately. In this case, equipping the workshop, you can meet literally 700,000 rubles. But many operations here will have to be performed manually, which means that the final profit will ultimately be much lower than in the case of automated machines.

And if we talk about a line with a capacity of 10 tons / h, then in this case the price of equipment for dry building mixtures will be at least 3,000,000 rubles.

Sales plan for finished products

The business in the production of dry building mixes will only become profitable when sales channels are debugged. And it is better if it is a wholesale sale of finished material, since many problems associated with idle equipment and stockpiling of goods in warehouses are immediately solved here. And in order for the mini-factory to start working already “for customers”, it is worth starting to look for buyers even at the stage of preparing a business plan.

Of course, if a franchise was used to open a factory, many problems with finding customers immediately disappear, since the company will produce a well-known product that does not need advertising. In all other cases, maximum efforts will have to be made to establish distribution channels for materials.

So, who will be interested in dry plaster building mixes and other materials produced within the walls of a mini-factory?

• Building bases, markets and shops.
• Construction and repair companies.

An option that will require much larger investments in the business is opening your own outlet. But in this case, the entrepreneur himself will be able to choose the form of sale of the goods and set his own price for it, as well as choose a convenient location for the store.

Another way to sell finished products is to organize an online store. But this option works better "in conjunction" with a real store.

Profitability of the planned business

It has already been proven in practice that a business in this niche can bring consistently high incomes. Having taken care of equipping the workshop and finding several wholesale buyers, you can run your own profitable business.

But before moving on to the indicators of the profitability of the enterprise, it is worth calculating the investment in the workshop. To purchase lines for packing dry building mixes and other machines with a capacity of 5 tons / day, prepare a room for work, stock up on raw materials and document the workshop, you will need at least 2,300,000 rubles.

If you buy used equipment or manual machines, you can start a workshop by spending no more than 1,000,000 rubles.

But you need to be prepared for the fact that investments can be much larger if you also provide your own fleet of vehicles to deliver finished products to customers. But a young enterprise can abandon this idea by offering self-delivery services to customers.

As for profit, the specific figure will depend on some factors:

• sales volumes,
• pricing policy in the region.

For calculations, we take the following data:

• Productivity - 3 t / h.
• Hours 1 shift - 8.
• The number of shifts per month is 30.

It turns out that with the uninterrupted operation of the equipment, it is realistic to produce up to 750 tons of finished material per month. And if you immediately sell products to customers at an average wholesale price of 3,500 rubles / ton, then the monthly revenue can be up to 2,600,000 rubles. If we subtract from this amount the costs of purchasing raw materials, taxes, salaries for employees, transport, communications and utilities, then the net profit can be at least 150,000 rubles per month. In this situation, it will be possible to pay back the enterprise after a year and a half. But these are good indicators of profitability.

The article will consider the features of the industry for the production of building materials using an example. The market is characterized by a high level of competition and a large number of players. This area is highly profitable, and new companies will find a place in it, subject to a thorough analysis of the existing opportunities and their strengths, which will allow them to stand up to competitors.

The main features of such a business are: the need for constant supplies of raw materials, the availability of specialized equipment and the possibility of year-round production of finished products. Packaged building mixes are widely used both in private construction and finishing works, and in the construction and repair of facilities by large companies.
