Sand concrete: GOST

Utilize dry formulations from various producers or make your own solutions. Sand concrete in grades M100 (150, 200, 400, 500) and M300 are the most widely used.

A state standard, GOST-7473, was registered for this building material in 1994. This standard defines sand concrete as a finely grained, light gray mixture intended for structural use.

GOST-specified material characteristics:

• particle size (graininess) — 100 µm — 3 mm;
• composition consumption to provide a layer 1 mm thick per 1 m² of surface — 2 kg;
• water absorption — 200-250 g per 1 kg of material;
• coating setting — 3 hours;
• complete hardening of the mixture — within 30 days;
• you can walk on the poured surface after 120 hours;
• possible loads on the coating after 28 days of pouring — 30 MPa.

The building material is composed of water, sand, and Portland cement. Due to its ability to accumulate heat, heated floors frequently use it in their layout. The state standard for marking building materials includes the letter "M" and numbers ranging from 100 to 500.

The following details are marked on the packaging:

• manufacturer;
• date of manufacture;
• sand fraction;
• curing time.

Area of use of building material

In construction, various brands of sand-concrete compositions are used to address the following issues:

• sealing of cavities and cracks in the base of the floor and walls;
• arrangement of inclined, horizontal screeds;
• construction of walls of buildings from aerated concrete, brick, gas silicate and other building blocks;
• concreting of foundations of structures;
• production of monolithic reinforced concrete products;
• construction of foundations and leveling of the base of the floor;
• production of decorative tiles for pedestrian paths.

Use of special sand-concrete mixtures

The composition’s grade is determined by its intended use. The strength characteristics of the building material increase with grade.

Labeling of dry sand-concrete mixtures, purpose, and a summary of characteristics:

1. M100 – waterproof concrete, which is used for leveling the floor surface, sealing defects and plastering bases. After hardening, it can withstand loads of up to 100 kg per 1 cm². The mixture has reduced the share of cement and no limestone, so that the material has an affordable cost.
2. M150 is a composition of wide application. It is often used for plastering and facade works. Strength – 150 kg/cm², which makes it possible to use the composition for brickwork and floor screeding. Sand of fraction up to 2 mm is used for the production of cement powder of this brand. The material additionally contains modifying additives that improve its performance characteristics. M150 is divided into universal, plastering, masonry, specialized compositions.
3. M200 – the material is used for interior work and arrangement of the "warm floor" system. It contains sifted quartz sand. After hardening, the coating is capable of withstanding loads up to 0.2 t/cm². M200 is highly resistant to local deformations.
4. M300 is a dry mix that is used for the construction of high-strength concrete structures, interfloor ceilings of buildings, for the arrangement of loaded foundation bases, floor screeds in industrial premises and the construction of load-bearing monolithic walls of structures.
5. M400 (500) — high-strength composition, capable of withstanding loads up to 0.5 t/cm², has found wide application in the construction of multi-storey buildings and industrial facilities. It is used for reinforced concrete structures and construction of residential buildings. The amount of cement in the composition is increased.

Which is better to use

It is advised to read the brand and manufacturer information found on the material’s packaging when selecting sand concrete. Since cheap mixtures use inferior Portland cement, their handicraft production cannot be considered high-quality. Additionally, metal elements corrode due to the composition’s high levels of sulfides and chlorine. The concrete layer may peel or crumble after it has dried.

Factory-made mixes are the most dependable because they are produced in huge quantities. They also contain plasticizers, modifiers, and other additives that enhance the material’s performance properties. The absence of additives resistant to frost is the only negative.

You must choose the purpose of the cement powder before purchasing it. Although the solution can be created on its own using the predetermined ratios of the ingredients in the sand concrete, the quality will not be the same as that of factory-produced goods.

This material is produced in two fractions: coarse-fraction (coarse sand) and fine-fraction (fine-fraction sand is used). The product’s grade increases with the amount of sand in it.

Suggestions for utilizing varying sand concrete grades:

• for leveling wall and ceiling surfaces, sealing joints between block building materials, you can use a low-grade material – M150;
• for laying bricks or building blocks, composition M200 is suitable;
• M300 is used for arranging floor bases, building concrete structures;
• high-grade material M400 is used in the construction of bridges.

Using dry sand concrete compositions with the following characteristics is advised in order to guarantee the building’s strength and lengthen its operational time:

• homogeneity of the finished solution;
• minimal shrinkage after drying of the coating;
• high strength of the material.

Every parameter on the list matches the M300 brand’s composition, which is one part cement and three parts sand. This is a versatile building material that isn’t just for screed placement.

Its low cost, reasonable consumption, and strengthened M300 brand make it suitable for use in resolving various construction-related issues.

When buying cement powder of this brand, the majority of professional and private developers prefer the brand "Rusean."

Additionally, experts advise utilizing sand concrete produced by the following companies:

• "Etalon";
• "Stone Flower";
• Brozex.

If the operating conditions are satisfied, their dry mixes blend smoothly with water and do not crack after hardening.

It is preferable to use "Stone Flower" building materials if exterior installation work is planned. This manufacturer’s cement powder is distinguished by its low aluminum content and enhanced resistance to frost.

Secrets of independent production

In order to prepare sand concrete in accordance with GOST guidelines, the following ingredients must be used:

• sifted medium-fraction sand with a binder Portland cement of high-strength grades (from M300);
• additives to improve the performance characteristics of the material;
• water to obtain the required consistency of the solution.

A homogenous mass must be achieved by thoroughly mixing the solution in order to produce high-quality material. It can be enhanced with dyes and fiber reinforcement.

Portland cement, sand, and plasticizers are the main ingredients of any brand of sand concrete.

Factors influencing the components’ concentration in the working mixture include:

• humidity of the raw materials used;
• marking of cement used for the preparation of the solution;
• purpose of the finished sand concrete;
• shelf life of the binder component.

In the preparation process, one part Portland cement can be mixed with three to five parts sifted sand, depending on the intended use of the building material.

The performance characteristics of a self-prepared mixture will not differ from similar factory-made material if you follow the guidelines for making cement powder and the requirements of GOST.

Detailed instructions for creating sand concrete by hand:

1. Sifted sand is loaded into a concrete mixer.
2. Portland cement is added to the sand according to the proportion.
3. The required volume of water is poured.
4. All components are thoroughly mixed.

With a small amount of water, a ready-made dry mixture of cement and sand can be added to a concrete mixer, according to technology.

Sand, cement, and water are combined to create the durable and adaptable building material known as sand concrete. It is available in different types and brands, each designed for a particular application such as wall construction, flooring, or decorative finishes. Compared to conventional concrete, the composition usually contains fine aggregates, which give it a smoother, more workable surface. Sand concrete can be customized for small-scale construction and repairs, and it’s easy to make at home with the correct proportions and mixing techniques for do-it-yourself enthusiasts.

Use for the foundation of a building

Sand concrete M300 is a great option for building foundation bases because it’s significantly less expensive and easier to prepare than other brands.

Any kind of foundation can be constructed using sand concrete:

• precast or block;
• monolithic strip;
• mixed.

Sand concrete can be used as a binder or as the primary ingredient in any of these options.

Sand with a grain size of 2.5 to 4 mm is one of the special dry mixes of the M300 brand that are made for strip foundations. These types of foundations have a lower bearing capacity than heavy foundations, but if the sand concrete is compacted with a vibrating unit, it will not have caverns or cavities in the hardened foundation.

Sand concrete M300 is frequently used as a binder solution and to fill in cracks between completed foundation blocks because of its high adhesion, ability to support loads of up to 300 kg per cm2, and other performance characteristics that make it comparable to other foundation building materials.

Preparation of the basis for laying sand concrete

On the finished basis, concrete is frequently used to make the floor screed. It could be panels of reinforced concrete or a screed. To pour the solution, any base needs to be cleaned up: fat spots and other pollutants should be rinsed, protrusions and construction debris should be removed.

Prior to applying the screed, it is advised to align the base if it has significant bumps. Concrete M200 (300) is appropriate for this. There must be two layers applied to the base after it has been cleared of debris and leveled before pouring. It is advised to use specific deep penetration primer mixtures for this, ideally with waterproofing qualities.

All of the joints, cracks, and fissures that already exist are covered with sealant once the primer has dried. Performing such a procedure is imperative in multi-story buildings. Entire room perimeter is covered with damper compensation tape.

Mixing the working solution

• water should be at room temperature;
• 1 part of water should be added to 5 parts of dry sand concrete;
• the solution should be mixed until smooth.

The lack of lumps in the mixture suggests that the sand concrete’s ingredients have been well combined. Within ten minutes, the mixture matures, at which point another thorough mixing is required. Since the finished mass sets quickly, it must be used up completely right away after preparation.

Features of working with sand concrete

Sand concrete powders must be used with caution, starting with the right working mixture preparation and leveling, cleaning, degreasing, and priming the surfaces before applying the powder.

It is advised to use these compositions when the temperature and humidity levels are at their ideal levels for building dependable and long-lasting concrete structures. Cement powder should only be used in positive air temperatures if it does not contain specific additives that prevent frost.

Working with sand concrete algorithm:

1. A solution is prepared according to the recipe.
2. The finished building material is poured onto the prepared base.
3. The working mixture is evenly distributed over the entire floor area and leveled. At the same time, the required thickness of the screed is maintained.
4. The sand concrete mass is tamped.

It is advisable to give the uncured coating time to dry and strengthen before loading it. It will require four weeks to complete. Simultaneously, for uniform solution hardening, the concrete needs to be moistened on a regular basis within 10 days of pouring.

How to calculate the need for sand concrete

You must know how much material is used for every 1 m³ of masonry or per 1 m² of poured area in order to determine the quantity needed.

1. For a floor screed, the area of ​​the room is multiplied by the material rate (M (kg) = S (m²) * Нр (kg/m²)).
2. To arrange the foundation base, the foundation volume is multiplied by the sand concrete rate (M (kg) = Vф (m³) * Нр (kg/ m³)).

The thickness of the coating layer must be considered when determining the necessary amount of dry composition.

It is advised to add fine-grained gravel (crushed stone) to minimize the usage of dry sand concrete.
