Organization of business for the production of dry building mixtures for the needs of building bases, shops, specialized companies and private clients - an excellent source stable income regardless of seasonality and other conditions. This is one of the fastest payback and not too expensive business ideas with a good return.
Dry building mixtures (CCC) are loose, powdery materials, when combined with water, it is possible to obtain adhesive, putty, waterproofing, plaster, assembly mixtures.
Ready-made compositions are stored for a short time, and dry building mixes make it possible to prepare the materials required for work at the right time and in the required quantity. The composition of the SSS is varied.
The basis of any mixture is
- binders
- mineral (silicate or aluminate cement, lime, gypsum, clay, etc.),
- organic (polymer powders and cellulose ethers, soluble in water),
- organo-mineral (polymer cement or polymer silicate compositions).
- Fillers - marble, limestone, dolomite, quartz, ash, slag, stone waste.
- Functional additives that accelerate thickening, hardening, giving strength, the necessary plasticity, frost and water resistance, etc.
For each specific recipe, depending on the purpose of the finished composition, its own ratio of binders, fillers and functional additives is used.
Is the production of dry construction mixtures promising?
The use of CCC has greatly simplified the task of builders and finishers. An extensive range of mixtures makes it possible to choose compositions with optimal characteristics for specific types of work. In everyday life or when performing large-scale finishing or construction works it is much more convenient to use a ready-made composition, which you only need to dilute with liquid, mix and use.
The current growth rate of construction and the demand for services for finishing and repairing residential, industrial and commercial premises have led to high demand for dry building mixes, making their production one of the most promising and fast-payback types of business.
Range
The following building mixtures are in particular demand, the production of which is worth building a business.
- Adhesives (tile, facade),
- cement screed mix,
- Compositions for self-leveling floors,
- waterproofing compounds,
- Putties (gypsum, cement, facade, finishing)
- Gypsum plaster
- Assembly mix.
Consumers
- Building materials stores and building bases.
- Internet-shops of building materials. This form of sales is in great demand today and brings no small benefit to manufacturers.
- Construction companies. The regular provision of construction and repair services requires a stable supply of quality materials.
CCC production by stages
The production of dry building mixes is a process chain consisting of the following stages.
- Preparation of components and their transshipment,
- Screening,
- Placement of raw materials in feed bins,

Business Ecology: Entrepreneurship related to the production of dry mixes can be suitable for both experienced entrepreneurs and those who have just started their activities.
Entrepreneurship related to the production of dry mixes can be suitable for both experienced entrepreneurs and those who have just started their activities. This idea is characterized by a high level of payback, as well as relevance in almost all cities of the country. That is why it is profitable production dry building mixes. business plan and all necessary documentation to organize your own enterprise for creating mixtures can be found already and in the finished state. However, you can do it yourself.
What needs to be done to properly organize the project?
In order to implement a project to create mixtures, you should get acquainted with the technology that is inherent in this type of entrepreneurial activity. You will also need to buy equipment, find regular suppliers raw material. After that, it will be possible to start organizing the production of dry building mixtures. The business plan should act as the main documentation.
Advantages of the implementation of the finished material
In the construction industry, dry mixes are used almost constantly. It should also be understood that you can always purchase ready-made products and simply sell them. Such mixtures have a large number of advantages compared to other materials.
1. Savings, both in time and in space. No need to purchase components, store and mix them
2. Even the most complex components in their composition can always be bought.
3. Money will be saved.
What is needed to organize a business?
Before you open an enterprise, you need to think about all the difficulties that can appear. The main difficulty is the search for those people who will buy products from the entrepreneur. In addition, you will need to register your entrepreneurial activity.
However, this problem is not so difficult to solve. As legal form it is worth choosing an LLC, since for the most part the cooperation will be carried out with legal entities. In order to establish the production of this type of sand, you will need to obtain a certificate from the fire service and a permit from the SES.
The payback of entrepreneurial activity will occur after about six months of active work. In some situations, by producing colored sand and other types of dry mixes, entrepreneurs pay for their business in just a few months. Profitability in some cases reaches 150 percent.
What can be said about the equipment?
The complex of a typical set of equipment includes the following devices: a vibratory container, a drying oven, a small intermediate hopper, a working platform, a batcher, a receiving hopper, a weight hopper. You will also need a mixer, a lifter, an intermediate hopper, a vibrating screen and a loader.
In that situation, if you decide to start your own business and the production of dry building mixtures was chosen as the direction, the business plan must be prepared with sufficient quality. It should indicate the restrictions from an economic point of view.
In other words, the entrepreneur must take into account the need to purchase a technological line on credit. In addition, you can purchase a ready-made plant for creating mixtures. Currently, there are no problems with this.
Key points to consider
It is necessary to take into account some parameters for those who plan to start the production of dry building mixtures. The business plan should reflect such nuances as the storage of powders, the dosage of components, drying, grinding, aspiration, packaging, etc. The process of creating products is the need for high-quality mixing of all components used, both basic and additional. The dosage should be taken into account, as well as the packaging of the final product.
A few words about technology
The production of building mixtures should begin with loading sand into a special vibrating container. After that, the material is transferred to the drying oven. After processing, the component is transferred to the vibrating screen through the use of a feeder. After that, the raw material passes into the intermediate hopper, from which it is subsequently loaded into the weigh hopper with the help of a vertical lift.
The creation of mixtures also involves the supply of cement, which occurs from a small intermediate hopper through the use of a hoist. The addition of additional components that define all the main characteristics of the final product is made from the job site.
Then the mixture in the finished state passes into the receiving hopper. After it, the material is sent to the batcher, which produces an overload finished products in special valve bags. When choosing equipment for the production of mixtures, you should pay all your attention to the volume that the mixer and hopper have. You will also need to take into account the frequency with which this device rotates, and its power.
The main criterion for the competent organization of the enterprise
Many criteria can influence the development of entrepreneurial activity. Therefore, it is quite important to draw up a good business project. Only in such a situation can one hope for a big profit. And over time, you can expand and start, for example, producing colored gravel or other types of building materials.
What economic costs will you face?
However, costs must also be considered. In order to buy equipment, you will need to spend about two million rubles. About 20,000 will be spent on renting the premises per month. Up to 600 thousand rubles will be required for transportation, as well as for the purchase of raw materials. On the wages employees will spend about a hundred thousand rubles.
By calculating all these amounts, you can get the minimum value of the initial capital. published

Production of dry building mixtures - step-by-step instruction+ 3 sales opportunities for finished products.
Capital investments: from 2.5 million rubles (on a leased area).
Payback: from 3 months.
Construction technologies have undergone many changes in recent years.
The simplest mixture of cement and sand, used several centuries ago, is now supplemented with new components so that all structures remain strong for many years.
Building mixtures are special compositions that contain a certain amount of various components in a strictly defined ratio: from aggregates to dyes.
To start production of building mixtures, you need to analyze what work is carried out in a particular region and what mixtures are used most often.
For example, buildings located near highways need soundproofing panels.
The subtleties of business organization, product distribution channels and financial calculations– you will find all this below.
What documents are needed to open a business?
To start a business for the production of building mixtures, you need to register the company as an LLC.
AT this case firm besides retail will be able to accept wholesale orders from enterprises cooperating with legal entities.
The following documents should be collected:
- copies of passports of all Members of the Company;
- copies of the director's and accountant's passports;
- decision on the establishment of the Company and the memorandum of association;
- statement about state registration legal entity;
- incoming cash receipts Money to the authorized capital of the Company.
For the production workshop, a room is needed, which must first be checked by the fire inspection and the sanitary and epidemiological service.
If all the requirements are met, the production manager will receive special certificates that allow participation in tenders of large companies.
You can do without a certificate, but this will not allow you to accept large-scale orders.
In this state of affairs, it is possible to draw up a refusal document, which will confirm that all manufactured products comply with established regulations.
Production of dry building mixtures: key points
Business plan - important document for any business venture.
To make a successful mix for the production of dry mixes, you should initially decide what will be sold.
All types of planned products should be clearly described, detailed recipes for their preparation, as well as a detailed composition.
Before starting production, an analysis of all the difficulties in this area of \u200b\u200bactivity should be made.
For example, request a loan from a bank, if not equity or look for investors to find a source of funding for the business.
For registration, only two permits are required, which must be issued by the SES and the fire department.
The business plan includes the following key points:
- range of construction products;
- choice of premises and equipment;
- sources of investment;
- raw materials for production (who will supply);
- staff (specify duties, salaries, work schedule).
Varieties and component components of mixtures
Building mixtures are necessary for cladding, masonry, installation, puttying and other similar works.For each composition there is a separate recipe for its manufacture.
The components in building mixtures are different, but the main ones are:
- mineral binders;
- special additives (to retain moisture);
- inert fillers;
- polymer binders.
Each manufacturer has its own exact recipe for a particular mixture, with a certain ratio of all components.
The finished mixture may contain gypsum, lime, cellulose ethers, various organomineral complexes.
The composition of the components allows you to determine how resistant this or that mixture is to temperature changes, in rooms with what level of humidity it can be used and how long it hardens.
To achieve a high level of stability, powdered superplasticizers are added to the composition.
The classification of mixtures is determined by the following indicators:
- What does the binder look like (with and without cement)?
- What is the dispersion level of the binder filler (usually coarse grain, up to 2.5 mm or fine grain, no more than 0.320 mm)?
- What is the purpose of the product?
Production technology: recipe and features
Each manufacturer has its own recipe, but the production process remains almost unchanged and includes the following steps:
- All components are carefully transferred, then sieved.
- Prepared raw materials are loaded into bunkers.
- Raw materials are used in strictly defined proportions.
- All components are thoroughly mixed, packaged and sent for storage.
There are many types of mixtures, as well as their compositions, but the basis is always cement and sand.
It is very important to pay attention to the fact that the sand in the dryer drum is well twisted and dried.
In this process, the sand is divided into fractions: from coarse to fine.
When the auger is completely filled with sand, the equipment stops automatically and must be emptied immediately.
Before receiving the finished product, all that remains is to wait for the system to thoroughly mix everything and send it to the packing bin, where the products will be already packaged and ready for transportation.
What is the difference between dry and liquid mortars?
Building mixtures are of two types - liquid and dry.
The second type of mixtures is most in demand due to its stable composition and long shelf life, even if the temperature is below the established norm.
At the same time, the quality of the mixture is not subject to changes in the process of construction work.
Dry building mixes have a lot of advantages: high uniformity, increased cohesion, water-retaining qualities and the ability not to delaminate.
A very weighty argument for the production of dry building mixes is also savings.
Such mixtures have a lower consumption, if necessary, they can be diluted in small portions immediately before facing or finishing work.
There are seasonal fluctuations in the trading sector, when the demand for goods falls sharply and then rises again and sales of liquid mixtures also depend on the time of year.
But dry building mixes have a longer shelf life - from 1 year or more, depending on the composition.
Therefore, the demand for them is distributed more evenly.
However, we can say that they are also a seasonal product.
Most sales occur during the summer season, from April to September.
What kind of premises do you need to start the production of building mixtures?
Without a room, it is impossible to imagine a full-fledged business plan.In addition to the production workshop, you need to decide on a warehouse, the area of \u200b\u200bwhich should be from 50 square meters. meters or more.
Equipment for the production of dry building mixtures
In the business plan, it is also necessary to prescribe all types of equipment that will make up a full-fledged production line.
There may be more than one such production lines - 2-3, depending on the planned sales volume.
One production line consists of the following equipment:
| Line equipment | Qty | Price, rub.) |
|---|---|---|
| Total: | RUB 21,450 | |
Mixer  | 1 | from 7 000 |
Packing hopper and auger  | 1 | from 1 800 |
Sand dryer  | 1 | from 10 000 |
Vibrating screen for screening  | 1 | from 1 700 |
electronic scales  | 1 | from 400 |
| commodity scales | 1 | from 400 |
Euro pallets  | from 20 | from 150 |
Such a production line can produce from 8 tons of products per hour.
Recruitment of the necessary personnel
Basically everything manufacturing firms work around the clock, producing products in shifts.
With such a schedule, day and night shifts for staff are drawn up, which should also be reflected in the business plan.
On the initial stage production in a team, not counting the manager and accountant, you need:
How much does a dry building mix business cost?
To start the production of dry building mixes, you need start-up capital required for the purchase professional equipment, payment of rent of premises and for salaries of employees.
Starting investment in business
Regular investments
There are expenses that the entrepreneur makes regularly (usually monthly).
Business profitability and payback
Each bag of dry building mix for 25 kg costs the manufacturer 60-70 rubles (product cost).
It is possible to produce a batch of 450 of the same bags per shift, which equals the total cost of 22,000 rubles (excluding production costs).
You can sell each bag from 200 rubles, and by selling a daily batch of bags, you can earn 90,000 rubles.
The level of profitability of this business is quite high - from 150%.
If the sales figures are stable and high, then soon you can recoup all the initial investments.
Experienced manufacturers call a period of 3 months.
The video below shows step by step process production of building mixtures:
Sales opportunities for finished products
For full-fledged and uninterrupted work on accepting orders for the manufacture of mixtures, a large customer base is needed.
It can be expanded through the following areas for sales:
- intermediaries specializing in the sale of dry building mixes;
- retail stores and markets;
At the first stages of production, the equipment should not work around the clock, without interruptions, so that later you do not have to write off the stale goods.
Although the shelf life of the product is quite long, it is better not to abuse this fact.
There is a lot of competition in the construction market, and in order to avoid losses, it is advisable to deliver mixtures at a distance of no more than 300 km from the production base.
Constantly expanding the customer base and assortment, the new production facility can produce up to 12 tons per shift in 5-6 months.
According to the experience of sellers and manufacturers of building mixtures, the return on investment will come in 3-4 months.
In half a year it is possible to achieve sufficiently high production rates - up to 12 thousand tons of products per shift.
This is possible with a diverse assortment of 15 different mixtures and attractive prices for wholesale and retail, as well as if equipment for the production of dry building mixtures will be of sufficient quality, and the process will not be stalled due to breakdowns.

Nowadays, any construction is carried out using building mixtures. And this applies absolutely. different types works: cladding, wall construction, wall surface finishing and others. In all such cases, various kinds of building mixtures are used. Their use is economically and practically profitable and justified. Such mixtures can provide high quality work performed, their effectiveness and high speed.
Today, there are many variations of recipes for the preparation and dilution of dry building mixtures, depending on the construction tasks. In addition, depending on which components are included in the composition of the dry building mix used to prepare the mortar, the degree of strength of the mortar, its resistance to temperature fluctuations, low temperatures, humidity, and so on can vary. That is why at present professional builders, instead of the traditional solution of cement and sand, which is prepared, as a rule, in the ratio "by eye", are increasingly using industrial dry building mixes.

As stated above, there are tangible advantages and benefits to the use of dry building mixes in the workplace. Let's consider some of them.
Firstly, the use of dry mixes saves time (and this is an important factor in the construction process) and space for storage and mixing (no need to purchase all the components separately, look for a place to store them and containers for mixing).
Second, due to the variability production process and upscale technological equipment European sample, it is possible to produce mixtures of varying complexity on an individual order.
Thirdly, the mortar can be prepared in the volume that is needed at the current moment, excluding the loss of dry matter.
Fourthly, the use of dry building mixes in sufficiently large volumes can significantly save the item of transportation costs, since in this case the need for a constant supply of ready-made mortar to the construction site is eliminated.
Fifthly, the use of dry building mixes always guarantees high quality, since they are prepared using the technologically correct recipe and the exact dosage of the components used.
As we can see from the above, modern dry mixes are a high-quality product of scientific technologies, which can significantly increase labor productivity and achieve high quality construction work. Which is quite difficult when using traditional solutions of cement and sand. It is not surprising that the manufacturing companies of these products keep their recipes for the preparation of building mixtures in the strictest confidence, but the components included in them and the main specific characteristics of the materials are widely known.
Specialists identify 4 main groups of constituent components of the composition of modified dry building mixtures. These are astringent mineral components, inert fillers, special additives (mainly water-retaining) and polymeric binder components (function on the same principle as mineral binders, but differ in the mechanism of action).
Given the demand and high quality of these products, the idea of organizing own business for the production of dry building mixes with subsequent sale promising business idea. Moreover, this product is quite in demand by construction bases, specialized shops, construction companies and individual clients. Therefore, the production of dry building mixtures can be a good and stable source of income. Moreover, this is not too costly production and quickly pays off.
The range of use of dry building mixes is quite wide. Since they are powdery bulk substances, which, when combined with water, give a variety of waterproofing, assembly, plaster, putty and adhesive mixtures. Plus CCC (dry building mixes) is also that they are stored well, unlike ready-made mortars, and you can prepare a solution from them at any time and in the right amount.
The composition of dry mixes can be quite diverse, but the following components always form the basis:
. astringents;
. fillers;
. functional additives.
The composition of binders includes mineral substances (these include silicate or aluminate cement, clay, lime, gypsum and others), organic derivatives (such as polymer powder, water-soluble cellulose ethers) and organo-mineral complexes (various polymer cement and polymer silicate compositions) .
The composition of fillers for SSS, as a rule, includes waste stone, marble, limestone, quartz, dolomite, ash and slag.
The composition of functional additives may be different. As a rule, these are substances that accelerate the process of thickening, hardening of an already prepared solution. And also these are substances that give the mixtures high strength, the necessary plasticity, heat and moisture resistance. The recipe for the preparation of the composition depends on its purpose in the future. It is on this that the use of binders, fillers and functional additives in various ratios depends, which in fact gives a different result.
What building mixtures can be produced by small businesses?
In the Russian construction market, most manufacturers began their business activities with the production various kinds tile adhesive. The technology for producing such glue is quite simple. And the manufactured products are quite profitable, especially under conditions of intensive growth in production.
It should be noted that the largest range regarding properties, as well as trademarks and prices of dry building mixes are offered mainly for the group of adhesives. In addition, the consumption of ceramic tiles in the construction market has increased significantly (up to 30% in 2003-2005). Over the past year and a half, there has been a slight decrease in the production of tile adhesives and, accordingly, the consumption of dry building mixtures.
This trend is likely to continue in the near future. According to experts, the ratio of consumer use of modified dry building mixes per Russian market will remain approximately as follows: tile adhesive - 32%, plaster adhesive - 32%, putty adhesive - 13%, floor levelers - 16%, and for other needs - 5%.
In the light of the foregoing, the question arises: will the production of modified dry building mixes be promising in the current situation?
It should be noted that the use of modified SSS greatly simplifies the work of builders-finishers. And a wide range of dry mixes allows you to choose the compositions that are best suited for specific types of work. Experienced builders note that both in particular cases and when performing large-scale finishing and construction work, it is an order of magnitude more convenient to use a ready-made composition, which is enough to dilute with water, stir and can already be used. Therefore, the demand for this product has always existed.
The high growth rates of construction in the modern world also determine the consumer demand for services for the repair, decoration of industrial, office and residential premises. And this, in turn, generates a stable demand for modified dry building mixes. Therefore, the business for the production of such products is not only promising, but also relatively quickly paid off.
Among the main production areas it should be noted:
- plaster mixtures;
- tile adhesive;
- masonry mortar;
- glue for gas and foam concrete;
- self-leveling compounds.
The materials used in production are available and relatively cheap:
- cement;
- granular sand (up to 0.6 mm);
- finely ground chalk;
- ground quartz, dusty fraction;
- functional additives (methylcellulose, starch ether, copolymer polyvinyl acetate).
The production technology of SSS is quite simple. The basis of most dry mixes is cement and sand. Despite the fact that the composition of the mixtures is constantly changing and improving, the production technology remains almost unchanged. Consider the stages of production in more detail.
The sand is sent to the dryer through the conveyor. The drum of the dryer rotates with a certain frequency, and with it the sand, which gradually spills out onto special blades located along the entire dryer drum. At the moment when the blade is at the top point of rotation, the sand begins to spill out and enters the hot air currents and, thus, dries. At the same time, excess moisture from the sand is removed from the room through ventilation. And already dry sand is poured onto a vibrating sieve, where it is scattered and divided into three different fractions: coarse sand, fine sand and screenings.
When a lot of dropouts accumulate, the sensor transmits a signal to the computer, which gives a command to stop production and remove the dropouts. In the same way, with the help of a computer, operations are carried out with sand, when a sufficient amount of it accumulates in intermediate bins, then intermediate augers come into operation, unloading sand into storage bins. With the help of a forklift, the finished cement is unloaded into a cement hopper and packed. Auxiliary bulk materials are poured into the hopper of additional materials manually. The system is automated, so the exact ratio of add. substances are entered into the computer by the responsible technologist, according to the recipe.
After that, the operator displays the name of the product on the computer screen and starts production. The computer, according to a given program, weighs each component and puts it into the mixer one by one. The end of each operation is notified by the computer in the form of a light signal on the display. The system performs the process of mixing the ingredients of the dry building mix. When this process is completed, the computer asks for permission to transfer the mixture to a separate filling hopper. This is where paper bags come in.
CCC production by stages.
The production process of dry building mixtures consists of the following steps:
1. Preparation and transshipment of the necessary components.
2. Screening of these components.
3. Placement of the necessary components in bulk bins.
4. Determination of the dosage of the components.
5. Mixing all the necessary ingredients.
6. Packing of the obtained mixtures.
7. Warehousing.
Naturally, each production stage requires the necessary equipment.
For those who want to buy ready business of course it's easier. You need to carefully study the market and the business plan, without wasting time looking for premises and equipment. And this needs to be given considerable attention, since the quality of the products to a large extent depends on this. So, for this type of business, you will need premises and equipment for the production of CCC and their packaging. It should be noted that European equipment is several times more expensive compared to the same but domestic production or made in China.
Video - Mini mixer with manual dosing but automatic filling::
At the stage of business formation, it is enough to purchase a minimum set of equipment. The installation of which will require a room with an area of 50 square meters and a height of about 7 m. Many manufacturers can order equipment of various configurations, according to the conditions of the customer. Payback production equipment the average is 10 - 18 months.
CCC packaging equipment can be purchased separately (manual or automated line) depending on the needs and financial capabilities.
Brief description and working principle:
Mini plant control system. The mini plant is quite simple to operate. It works with the help of a computer system. It can be controlled both automatically and manually. In addition, the use of such a system allows to reduce the number of personnel involved in production. And this contributes to a faster payback of equipment, and guarantees the stability of product quality.
Sand supply. Usually, a silo is used to store sand, with all the necessary extras. equipment. This includes: filter, safety valve, aeration system and level sensors. With the help of the screw conveyor of the VK series, already dry sand from the silo is fed into the sand weighing hopper. An integral part of the mini-plant can be a drum-type drying series "SP".
supply of cement. For the storage of cement, the same silo with additional equipment is used as for the storage of sand. Screw conveyor "VK" cement from the silo is fed into the cement weighing hopper.
Supply of supplements. Additives are weighed separately on special scales, after which they are poured into the mixer. The amount of additives used is calculated separately. After that, the mixture of additives is placed in a separate bunker of the VK159 screw conveyor and fed into the hopper-dosing device DMD150T, where all components are mixed.
Mixing components. Mixing is carried out in a CCC mixer. When the mixture is ready, the sensor is triggered and it is unloaded through the gate into the bunker. Level sensors monitor the volume.
Packing of ready mixes. Ready CCC is fed into a special bunker, which has valve bags for packing. After filling, each bag from the loading belt enters the conveyor belt and moves to the packaging area.

Prospects for the development of the dry mix market.
According to forecasts of analysts, in the near future such segments of the market of dry building mixtures, which are used for insulation and decoration of facades of premises, as well as for pouring floors, will actively develop. Moreover, preference is increasingly given to CCC based on cement and gypsum binders.
It should also be noted that the use of simple mortars is gradually decreasing and preference is given to dry building mixtures. And these are good forecasts for those who decide to open their own business. Ideas for Business from the section:
