The composition of the foam - the main characteristics and

Before undertaking the construction of a country house, most of the owners have long puzzled over the selection of building material. The choice of a modern developer presents a wide range of a wide variety of products, ranging from the usual ceramic and silicate bricks, to materials such as foam concrete blocks. Moreover, the composition of the foam to create such blocks may also be different.

It should be noted that blocks from different manufacturers may also differ not only in cost, but also in quality characteristics. For example, Aerok foam concrete has unsurpassed resistance to external influences.

What is foam concrete

Foam concrete or foam block is a stone of porous structure, which is a type of cellular concrete.

Note! Often foam concrete and aerated concrete are considered the same material, but such a proposition is fundamentally wrong.

The main differences of these concrete lie in:

1. Titles;
2. Manufacturing method:
3. In the composition of the foam present in advance prepared foam;
4. The porosity of the gas material is due to the release of hydrogen during chemical reactions;

Note! There is also gas-foam concrete, which is the result of combining these two methods of creating blocks of porous structure.

1. Structures:
2. Gas blocks consist of a set of open through pores;
3. The cellularity of the foam material is created by a variety of closed pores.

Composition

Foam blocks are a material that is not just porous, but breathable, capable of maintaining basic microclimatic parameters no worse than natural wood. Foam concrete - heat-insulating material with excellent parameters of durability and stability.

According to the requirements of GOST on cellular concrete at number 25485, the mixture for the manufacture of foam blocks should consist of the following ingredients:

• Portland cement acts as a binder in the solution. According to regulatory documentation in Portland cement for the preparation of foam silicate calcium should be less than 80%;

• In the foaming agent of such compositions include:

• Pine Rosin;
• Bone glue;
• Mezdrovy glue;
• Technical caustic soda;

Note! In addition to the sand in the manufacture of the solution used and other fillers. So, for example, with the participation of claydite it is possible to obtain expanded clay foam concrete.

Depending on what basis the frother is made, there are 2 main types of such substances:

1. Synthetic. The use of such a foaming agent allows to obtain products whose price is as low as possible, but at the same time the quality characteristics and strength remain at an altitude;
2. Natural. Such a substance is environmentally safe. Blocks with its use are strong due to the fact that they have a thicker partition between the supports.

Council Instructions for proper selection of material for construction also provides an account of the type of foaming agent used in the manufacturing process.

Different brands of foam concrete, in addition to the listed main components, may contain additional substances:

• Polypropylene reinforcing fiber or HSR fiberglass. Such a component is used in order to increase the strength indicators of the material being produced;
• Ash resulting from the combustion of solid fuels from thermal power plants. This ash is a fine-grained mass, the fractions of which may be less than a micron, and the largest particles have a size of 0.14 mm.

Main characteristics and types of blocks

Depending on the proportions of the main components of the composition used in the preparation of the mixture, you can get foam block or gypsum foam concrete, endowed with completely different characteristics.

Note! If, when creating foam blocks with your own hands, to reduce the amount of sand in the composition, the strength of the material will increase markedly.

There are several classifications of this material depending on the following factors:

1. By material density:
2. Structural, used for the construction of concrete foundations, basements and supporting structures. Marks of such concrete: D1000, D1100, D1200;

• Constructional and heat-insulating, used for the construction of partitions and load-bearing surfaces. Marks of such material D500- D900;
• Thermal insulation, used to perform surface insulation. Brands of this type of material D300- D500;

1. Thermal conductivity:

• Structural blocks are endowed with thermal conductivity within 0.29-0.38 W / m * deg. This indicator is less than clay brick;
• Constructional and heat-insulating blocks possess heat conductivity from 0.15 to 0.29 W / m * hail;
• Heat-insulating blocks possess heat conductivity in the range of 0.11-0.16 W / m * hail;

1. According to the method of manufacture:
2. Cutted. In this case, the finished large array of material is cut with the help of specialized equipment into pieces of a certain geometry;
3. Shaped. In this case, liquid foam concrete is immediately poured into specialized forms with partitions;

1. According to the method of solidification of the solution:
2. Autoclave foam concrete freezes in an autoclave, where optimal conditions are created for this;
3. The non-autoclave method assumes that the solution hardens in natural conditions.

Finally

Composition пенобетона - это набор основных ингредиентов и добавок, которые позволяют наделять строительный материал прекрасными показателями прочности, морозоустойчивости, влагонепроницаемости т.д. Поэтому вы сами вольны выбирать именно тот блок, который подойдет для ваших целей максимальным образом.
