Peskobeton: species composition, application, properties

Peskobeton - a mortar consisting of cement, sand and plasticizer. As the plasticizer used most often chippings. Another name peskobeton - fine concrete. In a simple concrete rubble is present up to 2 cm, and sieved through peskobeton with holes 3 mm network. Besides its particles have a flattened shape. concrete rupture due to freezing is due to the fact that the water gets inside. Due to the fact that there are no pellets in the pores, the water does not get inside and the break occurs. So the mixture is ideal for outdoor use. https://www.kirpich.ru/peskobeton/ - a material from different vendors.

Price peskobeton higher than normal. This is due to the fact that for the preparation of a larger quantity of cement is necessary, and it is - the most expensive element solution. In the role of rubble used coarse fraction of sand. Most often it is quartz sand, which is extracted from the bottom of reservoirs. In a simple concrete - fine sand. Also included in the peskobeton portlandttsement.

types peskobeton

Types and composition peskobeton prescribed for a visit. According to GOST granular particles in the concrete must have a size of from 100 micrometers to 3 millimeters.

Peskobeton M100 mark can withstand on 1 square centimeter load is not more than 100 kilograms. Stamps 150, 200, 300, 400, 500 can withstand a greater load - 150, 200, 300, 400 and 500 kilograms per square centimeter.

Durability is achieved by increasing the amount of cement and plasticizers application.

The best-known producers of this mixture are De Luxe, Holcim, Perel, Anchor, Stone Flower. In this case, each plant its own characteristics, such as the Stone Flower produces the most frost-resistant mixture.

properties peskobeton

1. frost-resistance - a material's ability to withstand repeated freezing and thawing. So peskobeton brand M300 must be kept for at least 50 of these cycles, so it can be used outdoors, or in rooms that are not heated.
2. Compressive strength It indicates a limit of the material of loads of different character before the start of the deformation process.
3. Temperature Range It shows at what temperature environment can be practiced laying. It is usually recommended to stack at a temperature from +5 to +25 degrees. But, applying antimoroznye supplements, you can do the construction work and to -15 degrees.
4. Adhesion - the ability of adhesion to other coatings. To improve this quality, you must carefully prepare the surface, on which is placed a mixture.
5. Bulk density It indicates the density of the non-compacted sand concrete.
6. The particle size of sand It may be fine to 2 mm, medium - 2 to 2.2 mm and a major - in excess of 2.2 mm. Small used for plastering, bug fixes; average - for tiles or ties; of erecting large foundations, make site.
7. peelability It shows how binds upper and lower layer coating. y peskobeton it is usually within 5%.
8. The right color solution - gray uniform.

application

Scope peskobeton is very wide and depends on the brand:

1. For example, pictures of the brand M-100 possibly plaster, patch defects, screed floor.
2. mix of mark M-150 ideal for bricklaying or plastering walls.
3. peskobeton M200 and M300 recommended for indoor use, pouring floors, underfloor arrangement, the construction of the columns.
4. mixtures M400 and M500 used in the construction of the foundations of high-rise buildings, it is recommended mainly for street work.

Peskobeton sold in finished form - slabs or blocks. Blocks, just like any other building material, are perforated and solid. Hollow possess greater thermal conductivity due to voids in which all the time in the air. Full-bodied building blocks stronger full-bodied, but require additional insulation in the construction of buildings and structures.

The material can be colored. This broadens the scope of its application. Color turns pale and the color palette is small. But for some design projects it requires just such a material.

Packing material and price

Standard bags with sand concrete - it's 25, 40 or 50 kilograms. If you see others selling packing - it is an occasion guard. This may be a non-certified concrete produced by unscrupulous manufacturers. Such a material cheaper certified, but it does not meet the quality standards no. On bags with sand concrete given its characteristics, as well as instructions for preparation.

Cost peskobeton higher than that of aerated concrete. Therefore, it is not very fond of private builders. But sand concrete slabs used for the construction of multi-storey buildings, as aerated concrete can not withstand such loads. But it is often used to reinforce conventional concrete, as its price is lower.

Peskobeton - relatively new building material. The price for it was formed from the cost of marketing and promotion. So I get inflated. Now the cost of the mixture gradually began to decline.
