What is sandbeton composition. What is sandbeton M300 and the characteristics of the building mixture. Secrets of independent manufacture

Peskobeton M300 is a very convenient and practical building material. The composition includes the proportions of such elements: Sand 67% and Cement 33%. Types of sand-concrete mixture depend on the size of the components, namely:

fine-sized grains up to 1.2 mm;
second-complete up to 2.5 mm;
local phrase - from 3 to 4 mm.

The most common is the range of sandbetone. The second place in popularity occupies a coarse-grained material, which is used to build foundation bases and basements. Peskobeton M300 fine-grained is applied a little less frequently.

Peskobeton M300 - what is it

Building material Peskobeton, what is it? A huge variety of mixtures are presented on sale, which are necessary in construction and repair work. With such a variety of products, you will need to choose a sand concrete with an acceptable price and high quality. Before applying the solution, learn the technical characteristics of the product. This building material is made in accordance with GOST 7473 2010 and GOST 28013 98, which will directly affect its characteristic qualities. In order to understand how much quality material is recommended to carefully examine the instructions for use. Thanks to the portland cement that is part of the component, the sand-concrete has good strength, density, frost resistance and other, negatively affecting the factors of the external environment.

For various purposes and destination, various filler fractions should be applied. If a sand-concrete mixture of M300 is required for the construction of a plate or a reinforced concrete structure, a gravel is recommended as a filler. When the composition is needed to cast concrete elements, the most suitable option will be dropped.

Areas of use

M300 sandbetone products are widely used in the construction of low-rise buildings. Since building materials are environmentally friendly and has improved characteristics, its scope is extensive. The characteristic of sand-concrete M 300 is influenced by the composition of bulk materials with different fractions. For example, a dry mixture with dense and stable qualities consists of small phrase elements that do not exceed 2 millimeters. Such mixtures have increased strength, they produce seam closures and are used to finish outside.

Dry mixture M300 Peskobeton in the composition, which includes fractions with dimensions of 2-2.2 mm, are most suitable for the construction of borders, pedestrians, bulk floors. The grain rate indicates good thermal insulation qualities, for this reason such a building material is popular in the arrangement of the bases for various floors for the floor. Also, the sandbetonic composition is used as a self-leveling material, the cost of which is much lower, if compared with special solutions. Due to the quality that excludes shrinkage, the field of application of sandbetone M300 allows you to use a solution in conditions with a complex soil. For example, in cases of unstable and prone to soil soil.

High strength and technical characteristics allows the use of a mixture in such construction areas:

Finished surfaces after hardening can be easily handled by various finishing options. With sandbetone M300, additional waterproofing will not need. Any work with the use of this solution will be more economical in comparison with foam concrete or brick.

The composition of Peskobeton M300

Sand-concrete composite is a universal mixture that is used in the construction everywhere. The component part has optimal operational properties. There is no accurate recipe for making sandbetone M300, due to the fact that numerous producers are different, the main elements do not change. The basic component includes such components:

Purified river sand with a fraction of no more than 4 millimeters. The sand fraction with a large fraction is also applied, it all depends on the purpose of using it.
Dry mixture of Portland cement M500, which is considered the main component in the mixture.
GROTSEV.
Plasticizer for sandbetone M300.

Enter additives should be in order to make a mixture of the required qualities. For example, the presence of special components makes it possible to use sand-concrete solution at low temperatures. In this case, the viscosity will become improved, and technological features will be strengthened.

For 1 ton of the building mixture, approximately 250 kg of Portland cement and about 750 kg of other components are included in the composition of Peskobeton M300. Each manufacturer has its own individual recipe.

How much does sandbeton dry? Surface collection will occur after 180 minutes. The possibility of surface treatment and movement, in two days.

Production technology

The mixture is produced at the factories, where the components included in the composition are mixed in accordance with a pre-prepared project. Also, the properties of the future solution are calculated in advance. Features of production:

All components are weighed.
Components are placed in the concrete mixer. This technique will make it possible to make a homogeneous mass of components that have different rigidity and viscosity interfering mixing process, obtaining homogeneity.
Stirring is made to obtain a homogeneous mass.
Next, the finished product is packaged and transport.

How to breed sand concrete?

In the application instructions, such recommendations are indicated:

capacity is filled with water;
after falling asleep out of the bag, dry composition;
the mixture is thoroughly mixed and left for 10 minutes;
further mixture is stirred again.

How much water is required for a sandbag bag?

At 40 kilogram bag of dry mixture, you will need 6.5 liters of water. If a plasticizer is added, then it is recommended to reduce the amount of water by 20-28%.

To do too liquid sandbetone is categorically not recommended, since such a feature will affect the quality of the finished design.

One of the main advantages of Peskobeton M300 is its ability not to give shrinkage.
Material has a high plasticity, quickly dries and harden.
Resistance to mechanical and other negative influences.
Ready elements are durable, environmentally friendly, resistant to moisture.
Building material is not terrible corrosion processes.
Acceptable price.

The advantage of this building material is zero indicators of water permeability. After full frost, when the building material is gaining the highest moisture strength in it will remain no more than 0.9%. If you purchased the PESCOBETON M300, where the additives are competently selected, the above data will become even lower.

The disadvantages include high thermal conductivity of sandbetone and low vapor permeability. For this reason, it is not recommended to erect with the use of this mixture of the wall and partition.

Reading time ≈ 3 minutes

Peskobeton began to be applied in construction recently. His story has no more than 15 years. Therefore, for many, this term is unusual. Hearing this word, people who are not knowledgeable in modern building technologies are asked: "Peskobeton? What it is?" But without him today is not a single stage of construction work. It is indispensable when erecting the foundation and in the interior.

Scope of application

The sand mixture is used to arrange high-strength floors in the utility and industrial premises, in basements and workshops. It can be used when creating sings, foundations as fine-grained concrete (it is to this category of concrete, it refers according to the classification of GOST). It is great for concreting stairs, joint processing, seams. It is taken as the basis for the repair of concrete walls, during masonry work. This mixture is used as a binding component when mounting structures from reinforced concrete.

Features of the composition

Produce the above material with mixing individual components in special modern installations. The composition of Peskobeton includes portland cement, large river sand, which is originally washed, plasticizers. The last component is used to improve performance. The proportions of the composition vary depending on the purpose of the specific variety. Separate grades of sandbetone have their differences in the composition. In this case, each recipe before launching in production withstands detailed tests. In the photo you can see how bags are labeled.

Specobetone specifications

In particular, the sandbetone M300, in addition to the above components, may contain a granite crumb or explorer. Features of its composition affect the operational properties. Among the important technical characteristics of Peskobeton M300, it is possible to note its ability to quickly harden, withstand frosts, do not pass water. These qualities make it possible to apply it in emergency repair work. It is advisable to use this brand in the construction of new objects, because it is endowed with high strength. A mixture of higher grades is used when construeding bridges and tunnels.

Main advantages

Conducting a comparison of sandbetone with similar mixtures, the specialists allocated the following advantages:

high wear resistance;
frost resistance;
safety for natural objects;
waterproof;
simplicity of preparation of the solution;
low price.

Therefore, sandbetone can well be replaced by other dry mixes commercially available.

Features of work with sandbetone

You can see on the video how easy it is possible to knead the sand-concrete solution. It is possible to work with this composition even in cool weather, ranging from 5 ° C. Cold water is added to the dry mixture to obtain a viscous mass of homogeneous consistency. You must not lose vigilance and add only a given amount of water. From how correctly the mixture will be prepared, it will depend on the possibility of coating to resist negative atmospheric influences. Here we can note one lack of sandbetone: when the amount of water is exceeded, such unpleasant consequences can be obtained like cracks, bundles.

After adding water, the solution should be spent within 3 hours. It is very simple to pour horizontal surfaces with this solution, it should be just pouring out and distribute over the entire area. If the surface has a notch, you need to pour these irregularities before filling the entire area. Reviews indicate that for the fill of one square. The meter of the floor with a thickness of 1 cm is needed about 20 kg of a mixture in dry form.

It is a building material, "middle" between classic concrete on a large filler and cement mortar, rejected on the sand. A wide scope of application and good performance supports the demand for this product last 10-15 years. Today, the mixture is dry sandbetone - a universal material that is present almost on each construction site.

Structure

Components included in the composition of the sandbetone:

portland cement M400 or M500 depending on the brand of the finished product;
sand of a large fraction up to 3 mm;
small aggregate - river sand.

GOST 25192-82 describes sandbetone as high density material, that is, it uses tight sand for its manufacture, the total volume practically does not give a shrinkage.

Depending on the specifics of the application, the mixture may include:

plasticizers and enhancers (for frost resistance, anti-corrosion, etc.);
granite crumb (dropout).

The composition of the sandbetone resembles a conventional concrete mix with the difference that in the first large crushed stone is replaced with large sand. As a result, the solution is obtained more homogeneous throughout the volume and convenient, with no less durable.

There is also the so-called sand-concrete suite. It includes an increased amount of cement, which makes the finished solution more plastic and rapidly frustrated.

How to cook sandbetone yourself?

The material is sold in the form of dry ready-made mixtures that simply need to be covered with water and use. This is a kind of alternative to the acquisition of solutions from the plants - no need to guess the proportions and select a suitable fraction and quality of sand with plasticizers.

To make a working mixture for construction work, take the required amount of packaged dry material and mix it with water in an amount of about 2 liters of liquid by 10 kg of dry components.

Proportions of sandbetone on average:

sand - 1 bucket;
cement - 3.5 kg (1 part);
water - 2.8 liters (0.5 parts).

The amount of ingredients may vary depending on the technical needs. For example, to obtain a more durable concrete, the amount of cement can be increased or reduced sand consumption.

Specifications

The technical characteristics of the sandbetone regulates GOST 7473-94. According to the document, the material parameters are as follows:

Indicator	Units	Regulatory
Maximum fraction

Consumption

Consumption of sandbetone on 1m² is calculated based on the layer thickness. So, for a layer of 1 cm thick, a flow rate of 1 square meter will be 18-20 finished solutions. Based on this data, it is possible to calculate the amount of material for a tie, surface repair.

To determine the need for a dry material in large quantities, it is sometimes necessary to calculate how many sand bags in 1m³. This can be done, based on the reference density of bulk materials - 2400 kg / m³. Manufacturers offer material in bags of 5, 20, 25, 40 kg. Accordingly, to find out the quantity, we divide the proportion for the mass of the net packing: 2400/40 * \u003d 60 pieces.

* Mass packing.

Brands

Peskobeton - the material is universal, as well as his concrete. The scope of the material is determined by the brand of the mixture and, accordingly, the finished solution:

M 100 contains small sand fractions up to 1.2 mm, so the solution has a prefabitability, is used as plaster for internal and external works. His strength is 100 kg / cm²;
M 150 is a plaster solution for internal and external walls, floor screed, brickwork. The strength of the finished concrete is 150 kg / cm². Its consistency allows the supply of a solution with concrete pump;
M 200 - Floor screeds with insulation and heated make preferred from this sandbetone. It has sufficient strength of 200 150 kg / cm²;
M 250 is a suitable masonry and plastering solution for the construction of small economic structures;
M 300 is a universal material for the preparation of a masonry solution, a mixture for filling the floors, the construction of buildings and individual structures;
M 400 Peskobeton is used to create responsible and highly loaded structures and structural elements, in special engineering structures.
M 500 is applied in private construction. It is rarely in mind an excessive high stock of strength.

Foundation

Different grades of sandbetone are used for construction from the construction of foundations to finishing interiors and design facades. This material is used in the same way as a conventional concrete solution, that is, they are indulging in water and applied by destination.

Sandob concrete M300 brand, M400 is suitable for the construction of the foundation. Moreover, the material will cost much cheaper than buying a finished solution in the factory, and the preparation accuracy will be similar.

It is noteworthy that the required amount of dry mixture is conveniently calculated - its volume almost coincides with the finished solution due to the minimum shrinkage.

Floor screed

For a tie of the floor it is better to use the M150 grade sand-concrete, if it is assumed to cover with linoleum, laminate, tile, or M200, if the heating system of electric or water type will be located in the body.

How to make a screed:

The base is prepared, remove the garbage, carefully moisturize.
Lighthouses are exposed - rails, which will make it easier for the process of moving the mixture.
Starting from the angle, the solution is thrown onto the floor and smash it with a construction rule or long rail.

When the warm floor is arranged before the fill on the base, the substrate and pipe (electrical) systems are placed.

He dries a screed floor from the sandbetone two days, after 2 days by the floor you can move, and after another 3 days already do the finish coating.

Plaster

Watching brick or concrete walls is usually carried out by cement solutions in view of their strength and good adhesion. Peskobeton for their preparation is the best solution. It is not necessary to calculate the number of cement and sand.

For plastering, it is optimal to use M100-M150 grades, which have a fine-grained structure, which allows you to carry out the perfect alignment of the surface. Also, the solution can be supplied to the walls by pumping.

Summary

Peskobeton is a universal building material, in fact, a relative of concrete. The dry mixture is convenient to embed for the preparation of masonry, plaster solutions and creating structures when building houses and structures of various purposes.

Sold and stored material in paper bags from 5 kg.

In the construction region, it is not possible to do without high strength. One of these materials is the sandbetone M300. It is a raped mixture consisting of quartz sand, portland cement and other bulk impurities. One of the advantages of using such a mixture is its supersaturation, i.e. it does not decrease in the volume after drying. Thus, it is advisable to use it for filling the foundation of buildings and structures, as well as when conducting finishing works, both indoors and outside.

To date, there are several grades of sandbetone. The only difference between them is the quality of sand, from which it is manufactured. It is due to the quality of sand, the sphere in which the sand-concrete will be used.

Nowadays, sandbeton enjoys very very popular. This is due to the universality of its use. It can be used for any type of construction work. The use of sandbetone, significantly reduces the weight that is assigned to the foundation. This is connected with the ease of sandbetone. In addition to high strength, the sand concrete has also durability and waterproof, which allows you to get rid of unnecessary hassle associated with waterproofing of the structure.

One of the best and most persistent grades of sandbetone is considered to be based on a low-iment admixture. Popular grades of Peskobeton today are considered to be the sand-concrete M 300, M 200 and M 500. M 200 - is intended for plastering and climbing cracks. M 500 - intended mainly for coupler, but can also be applied for other purposes.

However, the most discovered and demanded today is the sand-concrete M 300. The scope of its application is very extensive. Starting from various types of finishing works and ending with the foundation device. In addition to high strength, it has a mass of other advantages, in front of other types of sandbetone. Among its main advantages, you can select high resistance to low temperatures, water resistance and protection against many natural and atmospheric phenomena.

The sandbetone of this brand is also easy to use. All you need, for cooking it is water. The bay of it with water, and mixing until the homogeneous mass is obtained, it is enough to wait 5 minutes and after that, it can be used. It takes no more than two days on its solidification. Thanks to this short time, it is perfect, for filling the foundation. In addition, it can be used at a temperature of + 5 ° C to + 40 ° C. What is a rarity for concrete.

Water consumption at 50kg dry mixture of sandbetone is about 7.5 liters. The finished sandbetone is applied only on a pure and moisturized surface that does not contain dust and dirt.

As a rule, the sandbetone is produced in paper bags of 50 kg. It is necessary to store it only in a dry place. The term of its storage is not more than 6 months, from the date of manufacture.

To date, the construction market is littered with a variety of mixtures, materials that are necessary at various construction work and in similar processes. It should be noted that from such a variety of goods you need to learn how to choose not only inexpensive, but also high-quality material.

One of these materials is the dry mix of Peskobeton M300. At the moment, it is really popular among consumers of analog product. M300 includes sand, portland cement and some other additives. It is necessary to immediately note that sand concrete, like many other materials, is made exclusively at certain gestures, which ultimately determines its characteristics.

In order to understand how high-quality and necessary is the presence of a mixture of building components, it is necessary to carefully disassemble the topic - Peskobeton M300 Instructions for use, as well as carefully examine all available characteristics, and start it precisely from the composition of this material.

The composition of the sandbetone of the M300 brand

The composition of the dry mixture under consideration is universal, because it is definitely impossible to call it, but, despite this, it is used in the construction sphere everywhere. Its properties of operation can easily be called optimal. It is impossible to name the accurate "recipe" of Peskobeton M300, the composition depending on the manufacturers, it may differ slightly, but the main components remain unchanged.

Basic can be called the following components:

The sand is river (the simplest type of sand, the extraction of which is carried out everywhere, in any river career). Usually used for such purposes the sand fraction is not more than 4 mm.
The next component in this list is Portland cement (usually use M500). It is considered the main addition to the mixture.
The large-scale sand can also be used for the manufacture of sandbetone M300 (depending on what purpose it is going to use it).
In addition to the main components there are also other additives in the form of a granite dropout, of various types, etc.

It should be noted that the additives also play an important role, because from the presence in the mixture it allows the use of sand-concrete at low temperature indicators, the viscosity becomes better, and the technological properties increase.

On one ton of the construction material under consideration accounts for about 250 kg of Portland cement and about 750 kg of other components. In principle, each manufacturer "prepares" the sand concrete in his individual recipe, thereby trying to make a better and popular product.

Technical characteristics of sandbetone m300

Before moving to the consideration of the section - Peskobeton Instructions for use, let us find out what features the dry mixture is possessed.

The first parameter that we will look at will be a grade compression strength. It is necessary to note here, it is necessary to note that in days, 30-40, after frozen, the sandbetone M300 is capable of not deforming under pressure in 29 MPa (if it is really high-quality material). Due to the fact that in the construction suspension there are small sand, dust and precisely calculated dosage, at home can not be created similar material with the same technical characteristics.

Filling fraction may be different, it depends on the target, that is, the use of the M300 mixture. If we need to use sandbetone for casting plates and constructions from reinforced concrete, then it is better suitable as fractions of filling gravel, but if you need to use such a material for the production of products from concrete, then dropping is an excellent option.

One of the main advantages of the material under consideration is practically zero water permeability. After the frozen material drops its highest level of strength, moisture in it will be no more than 0.9%. If you purchase high-quality sandbetone M300 with properly selected additives, then the indicator in question will become even lower.

Frost resistance. In this case, you can immediately say that this indicator is high enough, and in practice it was proven not once.

The color of sandbetone is gray (depending on the quantity and type of additives can be a little lighter or darker). The material consumption is 2 kg per meter, the layer thickness ranges from 15 to 50 mm.

Peskobeton M300: how to calculate the flow?

The number of composite parts of the sandbetone is calculated so that the smallest particles are correct, evenly able to fill the space between sufficiently large fractional particles, and therefore the M300 density is larger, which is why the consumption of the material under consideration will be higher than that of other similar blends.

how to make sandbetone M300, composition and proportion

Consider the material costs must be necessary before the planning process begins. The amount of material being consumed, first of all, depends on the type and variety of construction work. If it is the process of casting designs from reinforced concrete, then conventional geometric formulas are taken into account here, because the reinforcement is not taken into account in this case.

For such a process, as a masonry takes into account the rate of consumption of sandbetone M300. To plastering outdoor coating, it is necessary to take into account both the thickness of the layer of the solution used and the direct surface area on which these works will be made.

In general, if it is necessary to calculate the consumption of solution, the formula and method of calculation can be found on the packaging of the material. Here is the expert consumption per square meter, if 1 cm layer, if you need to obtain consumption per meter cubic, the resulting value is simply multiplied by 100.

Instructions for the use of sandbetone M300

So, knowing the quality characteristics of the considered solution, you can decide how much it is suitable for a certain consumer with certain needs and if your choice is sandbetone, then you need to know how to apply it and what nuances you need to know about the process of using it.

So, the first stage is a thorough preparation of the surface. We clean the floor from various kinds of contaminants and necessarily, if necessary, dry it. If there are defects in the form of cracks and other deformations on the surface, they must be eliminated immediately.

The next tap is mixed with a solution and in the finished form we pour it into the treated surface. Before processing, it is desirable to slightly moisturize the surface to which our sandbeton will be poured.

Pluses at M300 abusely, the only nuance is that the solution can only be used if the ambient temperature is not lower than 60.

Working with the material is mandatory should be carried out throughout the entire pair of hours after the mixture is diluted. Peskobeton M300 Features and instructions for use will help properly and competently use it for its intended purpose. After 48 hours, it is already possible to check the strength of the surface being created, but the final result must be checked after the month of its pouring and fixing.
