Construction mixture on a cement-sand base

By doing construction works, the moment comes when it is necessary to carry out the facing of the structure. Today, a variety of materials can cope with this task, because the construction market is literally overflowing with them. Dry mix universal M 150 remains very popular. It is packaged in 50 kg bags. The versatility of these products lies in the fact that they can be used for different types construction work. And its price, consumption and quality fully meet the requirements of the consumer.

Dry universal mix M150 is very popular today. And this is not surprising, because it has many advantages. It is distinguished by high strength indicators, convenience in terms of preparation, high resistance to weather conditions, strong adhesion, the ability to apply in a thick layer.

But the products have their drawbacks. For example, the universal mix M150 is not suitable for concreting the foundation in multi-storey buildings. The reason is that it will not be able to withstand very strong loads - more than 150 kg per 1 cm3.

Dry mix universal M150 can be used when performing the following works:

  • masonry;
  • assembly;
  • concreting surfaces;
  • leveling the surfaces of reinforced concrete forms, as well as various structures.

With the help of the dry universal mixture M 150, you can perform a number of works to eliminate defects on the surface of such bases as brick, cement-sand, cement-lime, concrete.

Dry mixtures are classified according to their composition. Thus, cement and plaster products can be found in the store. The first option is budgetary. It can only be used when finishing. But this material cannot serve as a base. Its service life is short, after a while cracks and other defects may appear. You will have to spend money again and do the work again.

Cement

In the production of this mixture, specialists use cement. In addition, the mixture contains the following components:

Thanks to this composition, the resulting solution is convenient to use, it has high adhesive properties and after application and drying it is possible to obtain a reliable coating that is not afraid of moisture and retains heat perfectly.

Cement adhesive

This mixture includes two main components - plaster and glue. Its basis is cement.

The peculiarity of the composition is that it includes special fibers and polymer additives. Thanks to this, the solution acquires high adhesive qualities, does not crack and calmly repels the roof. In terms of work, this mixture is very convenient.

For what purposes it is used and how to apply it correctly, is described in this article.

But what dry building mixtures made in Russia are the best and most demanded, the information from this

Cement adhesive for tiles

Tile adhesive is a versatile building-based product. Since the composition contains special additives, the finished glue has high adhesive properties and excellent elasticity. This makes it easier to work with the solution.


Consumption

Before purchasing a mixture, you need to correctly calculate the flow rate. Thanks to this, it will be possible to know for sure required amount products and not spend extra money. When preparing a solution of liquid consistency M150, the dry mixture must be diluted with water, adhering to the proportion of 9 liters per 50 kg. But how to produce and use and how to do it correctly, is described in the article.

If a solution of a smaller amount is required, then adhering to the indicated numbers, you can determine the necessary proportions with your own hands. When thorough mixing has been done, leave the mixture for 5 minutes. Then stir again. The ready-to-use solution is ready for use. The mixture begins to set in 1.5-2 hours.


The consumption of the mixture depends on which surface will be treated:

  1. If you need to level the floors, then it is worth using a mixture with the following consumption: 2 kg per 1 m2, while the layer thickness will be 1 mm. If you are going to fill a floor of 20 m2 and a thickness of 30 mm, you will need 1200 kg of products or 24 bags of 50 kg. Calculate this is obtained using the following formula: 20 * 2 * 30 \u003d 1200 kg. The poured floor will fully harden after 28 days.
  2. When carrying out outdoor work, the maximum and minimum permissible air temperatures must be taken into account. The universal mixture M150 will be kneaded and used at a temperature of +5 - +30 degrees. Before applying the solution, the surface must be prepared, fragile areas must be removed. Then degrease it and remove dust. This will maximize the adhesion of the applied product layer. Before starting work, it is necessary to thoroughly moisten the prepared surface.

Today, construction markets offer a huge variety of different building materials, but M150 dry mix is \u200b\u200bone of the most popular and demanded. It is a versatile tool for preparing and finishing, plastering and leveling any surfaces: walls, ceilings and floors. Dry mix m150 is also used for laying tiles, for concreting and repairing stairs, ceilings and others reinforced concrete structures, for finishing slopes when installing windows and doors. It is inconceivable to carry out any other installation or masonry work without this assistant. In addition, the mortar applied using this cement-sand mixture is easy to apply and adhere to virtually any surface, be it concrete base, cement-lime and cement-sand, as well as brick surface. Simple use and quick drying (within 24 hours) of this material will shorten the time of any construction process.

The economical consumption of this building material (1.8 kg / m2 with a sufficient thickness of the applied solution of 5-50 mm) and rather reasonable prices for dry mix m150, especially in the company "LuxStroy", also determined the high demand for this construction product. By using it, you will save time and effort for any installation and construction work, major or current repairs.

High quality and excellent strength characteristics that are inherent in this material due to the special composition and manufacturing technology, they guarantee the reliability, safety and durability of the surfaces finished with it and the entire constructed structure as a whole.

Distinctive characteristics of dry mix m150

This bulk material gray made of Portland cement PC 500D0, PC 400 D20 with the addition of sand, various impurities and modifying polymer additives that improve the quality and binding properties of the building mixture. Depending on compliance with a certain GOST (10178-85 or 30515-97) dry mix m150 can be produced from Portland cement grades PC 400 D20 or PC 500 D0 with the addition of dry, fractionated sand (composition of fractions combined 0.1-1.25 mm ( TU 5711-002-05071329-2003)). To induce a homogeneous thick and elastic mortar, it is enough to mix 1 kg of the mixture and 0.17-0.19 liters of cold (t \u003d 15-200C) water and stand for 5 minutes.

The special manufacturing technology and the optimal ratio of the components of the building dry mix M150 makes it frost-resistant, high-strength (with compression 15 MPa, tension 0.5 MPa), reliable and durable. In addition, our M150 dry mix will give your new coating excellent heat and sound insulation properties. And due to its low hygroscopicity and water retention capacity of at least 92%, the induced mortar remains elastic and usable for two hours, preventing premature hardening.

Features of using dry mix m150

It is better to work in dry conditions at an air temperature of 5-300C. It is necessary to apply the ready-made solution on a surface that is free from dust and dirt, as well as from the remnants of the old coating and building materials, if possible on a dry and degreased flat surface. In conditions of increased dampness, in order to avoid the growth of microbes, the spread of rot and mold, the base must be first cleaned with a steel brush and treated with fungicidal preparations before applying the mortar. If the surface is very absorbent, then before applying the mortar based on the cement-sand dry mix M150, it must be moistened as much as possible and primed in several layers to enhance adhesion and increase the reliability and durability of the new coating.

If there are large cracks, they must be filled with this solution, and then the surface can be leveled by applying several layers and evenly distributing the mixture with a trowel or a mounting net. Each new layer of mortar based on dry mix m150 is applied after the previous one has completely dried. 24 hours after applying the last layer, the surface can be painted or wallpapered.

The dry mix M150 should be handled very carefully, avoiding contact with the skin and even more so with the eyes, because it contains cement and, when combined with water, gives an alkaline reaction. It is best to use auxiliary tools and work with gloves.

Cement mixtures are the most common material that people use during construction and renovation worksoh. They are made on the basis of cement and sand. In order to improve the technological properties during production, various additives (plasticizers) are introduced into the product. Engage cement mixtures at all stages of production, starting with the installation of the foundation and ending with plastering the walls.

To obtain the finished composition, you just need to add water and stir for a few minutes. Due to this ease of preparation, such formulations are very popular. Let's consider in more detail technical properties M150, as well as methods of its application.

Dry CMK mixture M150 is used for plastering walls, ceilings and other surfaces. In addition, this material can be used, provided that the subsequent processing will be painting, filling and wallpapering.

Cement mix M150 can be used for laying walls, concreting stairs, repairing floors, embedding concrete walls and areas where there is fallen off plaster. Such a composition can be applied to a surface made of concrete, brick and cement. The applied layer thickness will be 5-50 mm.

How to apply

When you purchased the presented mixture in bulk, then it is poured into a container at the construction site, into which water is then sent. To obtain a homogeneous mass, it is necessary to thoroughly mix the resulting composition. When preparing the M150 mixture, the following proportions must be observed: water consumption 1.8 - 1.9 liters per 10 kg of dry mixture.

What are the brands of cement and their application indicated in this

It is necessary to apply the ready-made mixture with the help of a trowel or spatula, but this must only be done on the basis of the preparation in advance. After the mixture is ready for application, then it is worth taking care of moisturizing the surface.

In addition, the surface must be dry, structurally sound and cleaned of various kinds of contamination. Make sure that there are no old materials on the surface, otherwise it will be impossible to achieve good adhesion. If there are crumbling and fragile areas, they need to be removed or repaired. For areas covered with moss, algae and fungus, it is worth cleaning with a steel brush.

After that, be sure to apply fungicidal compositions. If the surface is highly absorbent, then before applying the composition it is worth moistening or priming in several layers. In this case, be sure to wait until the first layer is thoroughly dry.

Where and how to use grade 400 cement is indicated in this

Now you can proceed to preparing the mixture itself. Place the required amount of clean water in a container. Its temperature should be +15 - +20 degrees. During the receipt of the solution, you should clearly follow the instructions. To obtain a solution of the desired consistency, water consumption can be 190 ml per 1 kg. Gradually add the dry mass to the liquid and mix thoroughly with a mixer or drill with a nozzle. It is necessary to stir the composition until a homogeneous mass is formed. Wait another 5 minutes, and then stir again, but you do not need to add water. The finished composition can be mixed when it is started.

After all the preparation work has been completed, then you can proceed to finishing activities. First, you need to fill in large defects and cracks. The solution can be applied with a spatula or brush. After that, smooth it well using the rule and grout. The grouting process can be carried out using a steel or plastic float.

What cement consists of, you can find out from this

When the layer thickness exceeds 30 mm, then it is worth using a plaster mesh. If you carry out the process of leveling the wall, then you will not have to apply the M150 mixture in one layer. But it is necessary to distribute the next layer only on condition that the previous one is already completely dry. After drying, the top layer must be leveled and rubbed. After grinding the base, and then you can proceed to gluing the wallpaper. But this can be done only after 24 hours, when the last layer was applied.

During the performance of all work, it is important to observe the temperature and humidity conditions. All work should take place in a dry climate, and the air temperature should be +5 - +30 degrees. And the humidity level should not exceed 80%.

How to use is indicated in the article.

You need to store the purchased mixture indoors and no more than six months. Otherwise, the M150 mixture will lose its properties. The manufacturer guarantees that the mixture is dry, if all the rules for storage, transportation and use have been observed taking into account the requirements of GOST 28013-98.

Price

Speaking about the cost of the presented product, it should be noted that it will depend on the volume sold. For a bag weighing 25 kg, you will have to pay 78 rubles.

What is indicated in this article.

Dry mix M150 is a popular product that is widely used for plastering any surface. The unique properties and composition allow to achieve excellent adhesion to the surface, increasing its strength. After such treatment of the base, all subsequent finishing materials will remain on the surface for a long time.

On the list of the most common materials on construction sites are cement mixtures. They are based on cement and sand, but various additives (plasticizers) are introduced into the composition to improve the properties. DSPs are used at almost all stages - from foundation installation to wall plastering. The dry mixture should only be diluted with water in the proportions indicated on the container, and kept for a few minutes until the correct condition. It is the ease of use that has made it so popular.

The cement-sand mixture is the basic building material for pouring foundations, masonry walls; leveling floors, plastering surfaces and sealing joints.

The brand is determined based on the specific type of work:

Plasticizers expand the range of applications. Thanks to additives, adhesion (the degree of adhesion of dissimilar surfaces), water-repellent properties, and mechanical stability of the finished DSP change. Their presence also affects the price of the material in the direction of its increase.

GOSTs and marking of DSP

The technical parameters of dry cement-sand mixtures are regulated by the provisions of GOST 28013 (1999). The classification is carried out by:

  • density (light, heavy);
  • the number of astringents (simple - one, complex - several);
  • purpose (plastering, masonry, filling).

For solutions based on a mixture, GOST regulates:

  • humidity;
  • density;
  • temperature range;
  • plastic;
  • delamination.

The hardened mass is evaluated by:

  • density;
  • strength;
  • frost resistance.

The M200 marking indicates that 1 cm³ of the hardened mixture can withstand a static load of 200 kg.

The container in which the DSP is packed must convey to the consumer complete information about the composition, method of application and shelf life. The manufacturer is obliged to indicate the technical characteristics of the cement-sand mixture:

  • class of materials;
  • concrete grade for compressive strength (MPa);
  • additives used (type, amount);
  • maximum aggregate fraction (mm);
  • volume of water to obtain the finished mass (l).

In addition, the container displays the trademark of the manufacturer itself, weight, release date, expiration date.

DSP application

This is a cement-sand plaster mix. The composition includes cement, river sand and lime. For 10 kg of dry matter, add 2 liters of water. The price is not high as little cement is used.

Available in several modifications. Accordingly, it is suitable for plastering, grouting, installation and masonry work inside and outside buildings.

Assembly and masonry M200 - the best way for walls. In a universal composition, it is also suitable for strip foundations... The third version of the cement-sand mixture is plaster.

4. M300.

Cement-sand mixture M300 (sand concrete) is intended for concreting work that requires high strength of the finished layer. It is used as the main material for pouring the foundation or concrete screed, arranging the floor in places with high traffic. It consists of cement and sand of various fractions, it is used both inside buildings and outside. The cost of a bag of sand-cement mixture M300 weighing 50 kg is about 140 rubles.

It is the most durable, frost-resistant and plastic sand concrete for bases, floors, load-bearing structures, outdoor areas, reinforced concrete products. Cement predominates and many plasticizers are added, which makes the cost of M400 high.

Average consumption

Any amount of money announced for the bag does not make sense until the amount of consumption is indicated. And it can differ several times for the same area, it all depends on the thickness of the layer. Consumption per 1m² of dry cement-sand mixture is in the range of 1.7-1.9 kg. But manufacturers indicate it based on 1 mm of thickness.


The processing of a square meter of surface with a 2 mm layer will take about 3.6 kg, and with a 5 mm layer - about 9 kg. As practice shows, when pouring floors with a layer of 10 mm, 21-22 kg of cement-sand mixture per 1 m² are consumed. Based on this situation, more than 400 kg of M300 sand concrete will be used for 20 m². Therefore, in order to save money, many individual developers do not use the factory composition, but prepare it themselves.

Types of solutions

1. DSP for floor screed of residential premises.

The solution should be grade 150 or 200. To achieve these parameters, you can take cement M500 and sand in proportions - 1: 3 or cement M400, but in a ratio of 1: 2. It is advisable to add 800 g of fiberglass per cubic meter.


2. Plastering of surfaces.

3. Wall masonry.

In this case, special attention should be paid to the purity of the sand, if necessary, sift it. Only under this condition will the binder and aggregate turn into a homogeneous mass that will reliably hold the bricks together. The proportions range from 1: 3 to 1: 6. 1 part of cement relies on 0.8 parts of water.


How to prepare a building mixture?

There is misconceptionthat it is enough to mix the sand, cement and water well enough to get the right consistency. In fact, the first step is important - mixing the binder and aggregate. It is the even distribution of cement that will guarantee a good mortar. Dyes can also be poured into the base dry cement-sand mixture to obtain different colors. After a homogeneous sand-cement mass is obtained, the liquid is gradually poured in.

If a concrete mixer is available, water is first poured into it. Next, cement is added, the composition is brought to a homogeneous state and only after that the sand is poured out.

Experienced builders have their own secrets:

  • If there is little cement, the strength in the cured form will be weak, and an excessive amount of binder makes the cured cement-sand mixture brittle.
  • Can be strengthened with sand, but the plasticity will decrease.


Average prices

In many cases, developers prefer to use ready-made dry mixes. By pouring in water according to the instructions, in a few minutes you can get the correct solution. Ease of use and quality ingredients, including the necessary additives, speak in favor of CPA. The cost is determined by the brand, the cheapest is M100, and the most expensive is M400. The weight of the package is also important: the price of 1 kg in a 25 kg bag will be higher than in 50 kg. For large construction cement-sand mixtures are packed in containers up to 1 ton.

Starting any construction work, we want to do everything in the shortest possible time. It's no secret that protracted construction is annoying, and repairs, as they say, are akin to a fire. We also want quality and without problems, so that after that you do not have to finish or redo it. And what can we say about costs! We never have enough money.

The current technologists for the production of building materials help to fully satisfy these desires. Among the materials that can simplify and reduce the lines of construction and decoration of the room, and at the same time inexpensive in price - dry building mixtures.

They consist mainly of lime, gypsum or cement (the basis of the mixture), to which all kinds of additives are mixed. They give these mixes important qualities. The most significant among them are polymers. It is they who provide the adhesive ability of these binders.

Simple, strong and reliable

Today the building materials market abounds in a variety of such mixtures, but cement-sand M150 remains the most demanded and popular. And not surprisingly, it is very widely used in construction.

Sandy using M150 is easy to install and quickly hardens on any surface, be it concrete, limestone or sandy coating, brick wall... The mixture is easy to use and dries quickly, within a day.

It is thanks to these properties that its construction is rapidly progressing to the finish line.
The main advantages of using this binder are:

  • economical consumption;
  • universality in the field of application;
  • high quality composition;
  • reliability;
  • full compliance with standard norms.

The special composition and manufacturing technology of this mixture ensures its relevance.... It is made on the basis of Portland cement of various brands (depending on which GOST the product must comply with), with the addition of sand, polymer additives and various impurities.

All this improves the quality of M150 and the viscosity. This approach ensures environmental safety and durability of those facilities where it is used.

With the help of this mixture, which can be used both for work inside and outside, walls, ceilings and other surfaces are plastered. Moreover, she will behave normally when painting, filling or wallpapering, which will follow.

DSP M150 can also be used for the construction of walls, cementing or staircases, patching up cracks on walls from and areas with damaged plaster.

It is also suitable for leveling the ceiling (in this case, you do not need to use a reinforced mesh), however, the cementing layer in this case should be 3 cm thick.


By the way, most of all this cement-sand mixture is used at home... The basement, the floor are poured with a solution made from it, wall segments are erected, especially in the garage and basements, various fences are produced and much more.

The mixture has the following properties:

  • a strong degree of adhesion to all kinds of surfaces;
  • vapor permeability;
  • weather resistance;
  • frost resistance;
  • durability.

It is prepared right on the spot, without any intricacies and easily.

The mixture is simply filled with clean water (for 25 kg you need to take 3.3-3.8 liters, for 50 kg - 6.5-7.5 liters). Then everything is mixed until uniform by hand or with a construction mixer at low speeds.

After that, the solution is left for 5-7 minutes and again quickly stirred.


If its consistency is homogeneous and plastic, then it is ready for use. It must be used within 2 hours.

Technical reputation

Cement-sand mixture M 150, as already mentioned above, manufactured in accordance with GOST, therefore, has the following technical characteristics:

  • appearance - gray loose homogeneous mixture;
  • application temperature - from +5 to + 30C;
  • filler size - 0.8 mm;
  • water consumption per 1 kg of dry mix - 0.13-0.15 liters;
  • per sq. m - about 16.5 kg (1 cm);
  • dry mix consumption per 1 sq. m with an application thickness of 1 mm - 1.9 kg;
  • the average density of the hardened mixture is 1500 kg per cubic meter. m;
  • the thickness of one layer of the solution is 5 - 40 mm;
  • water retention capacity - 90%;
  • this mixture sets in 2 hours, and hardens for 24 hours.

Buying M150, it does not hurt to pay attention to what of the additives it contains. For example, is it hardy? An important indicator will be the thickness of the layer of its consumption per 1 m2, which is recommended by the manufacturer.

Application

Working with the M150 requires compliance with certain rules. But they are no different from the procedure for using other building mixtures of this type.

From the very beginning, you should be especially scrupulous about the preparation of the surface on which the solution will be applied.

If it is a wall, then it must be completely free from dust and dirt, plant residues, etc.


If there is old plaster, it is removed in those places where it does not hold firmly... Only then can a new solution be applied.


But for this you need to cook it. For walls, the proportion is as follows: for 10 kg M150 2 liters of water. It is advisable to take clean and cold, but not very much, about 15 C. If necessary, you can add more liquid.

The solution is made like this. The mixture (dry) is gradually added to the water and mixed... When the mass becomes homogeneous, let it stand for about 5 minutes. And then it must be quickly mixed again. The batch should be worked out in 2 hours.


When applying plaster to the surface, it is necessary to cover all cracks and holes with it, if any. And only then level the entire surface. As a rule, myself the solution is applied with a spatula, and leveled with a float.


If work is carried out from the outside, then before that surface reinforcement should be organized, using for this reinforcement mesh.


М150 is considered a universal brand among similar cement-sand mixtures. She behaves well during various technological operations. This mixture, if necessary, can replace any other. Therefore, it is in demand in the construction market.

Price

In addition to its technical characteristics, this cement-sand mixture also attracts with its price, which depends on which solution it is intended for the preparation of. Various additives also affect the cost, since some are not cheap, for example, plasticizers.

It is quite understandable that adding them to the mixture will raise the price for it. So let's talk about the average price, because the final price is subject to many factors.

The price depends on the manufacturer, the composition of the mixture, delivery to the point of sale, etc. On average, a 25 kg bag of M150 mixture costs 91-92 rubles per one, which is quite acceptable.

By the way, if mixtures with similar characteristics are on sale, then before making a purchase, compare their consumption in kg / m2 per layer thickness. It happens that a mixture that is more expensive will save money.

Consumption

Of course, whatever the cost of the mixture we indicate, it does not make sense without the volume of its consumption. And it can be different for the same surface. It all depends on the thickness of the applied layer. According to the technical characteristics, this figure for the M150 is 1.9 kg of dry mix per sq. m, but with a layer thickness of 1 mm.

Sand is rightfully the most widespread and popular building material due to the fact that it has excellent properties and qualities. you can find out how much a cube of sand weighs.

Among the great variety finishing materials in construction, Rotband plaster is rightfully considered the best. all its technical characteristics.

When carrying out any repair work, you must understand that the floor must be reliable and durable. By going to get acquainted with the technology of laying dry floor screed.

As you know, when filling the floor with a layer of 10 mm, this figure will be 20-22 kg per square meter... And 20 sq. m, respectively, - more than 400 kg. Therefore, in order to save money, many private developers still prefer to prepare such mixtures themselves, rather than buying ready-made ones.

By the way, the consumption of the mixture per 1 sq. m is designed for craftsmen. Therefore, when deciding whether to purchase, consider this. For screed or masonry you you will actually need 8-12% more solution.

What is this information? The document says not only about the purpose of this product, but also states:

  • substances;
  • initial moisture content of the mixture;
  • range of permissible temperatures for use;
  • parameters of plasticity and delamination;
  • frost resistance indicator.

Indicators of the average consumption of a substance for certain types of work with a solution can also be added here. A necessary point is the safety of the material for humans and the environment.

Precautionary measures

Although the M150 mixture is not poisonous, it is made on the basis of cement, which, in contact with water, can inflame the skin. Therefore, it is advisable to work with the solution with protective gloves. Eye contact can also be painful.
