Foam blocks and aerated concrete .All you need to know.

Air blocks - basic information

Foam, the main component of the foam block, - a subspecies of concrete with a mesh, porous structure.This concrete are air bubbles distributed in the whole volume.The bubbles are formed by a mechanical (not chemical, as in aircrete) mixing.Self foam is prepared by mixing the foam concrete.Foam is made in a special baroustanovke (or steam generator).

This type of concrete has reduced rates of humidity and thermal conductivity.The positive properties can also bring: environmentally friendly, fire resistance, low setting time.

Good resistance to all weather conditions allow foam blocks be used in all climatic zones.

What other useful properties are concrete blocks?The characteristics of this material should be considered by the physical properties.

type foam	Brand density	Class by compressive strength	Mark on frost resistance
Insulating	D400	B0,75	not normalized
D500	B1	not normalized
constructive insulating	D600	B2,5	F15 - F35
D700	B3,5	F15 - F50
D800	B5	F15 - F75
D1000	B7,5	F15 - F50
Structural	D1100	B10	not normalized
D1200	B12,5	not normalized

As can be seen from the table, concretes are divided into classes according to compressive strength.Each class is made with the expectation of a certain load, taking into account safety factors.

make a particular type of foam blocks foam shows what kind of load on one square centimeter, it can withstand.Mark denoted by the letter M + "numbers", for example M26.Such marking indicates that the product is able to carry loads up to 26 kg per 1 cm2

Class frost resistance indicates how many successive cycles of freezing and thawing can withstand foam.For example, F15 means that the product can be safely subjected to freezing and thawing 15 times.

Useful properties of foam blocks

blocks, the characteristics of which shall be appointed in accordance with modern GOST and SNIP, shall ensure the following conditions:

• reliability.Foam concrete is rot-resistant, has high strength.All this increases the service life compared to conventional concrete.
• insulation.The costs of heating the room from the foam blocks can be 30% less than in the premises of another material.
• Soundproofing.Not the strongest side of the material, due to the cellular structure.But the requirements of GOST on sound transmission are performed.
• Environmental cleanliness.Air blocks do not emit any toxic substances.And they ignore environmental factor brick (better only tree).
• Easy to transport.Due to quite low weight and volume, concrete blocks is very easy to transport.
• Resistance to fire.Foam through the porous structure has a high degree of fire resistance.Often it is used for special fire protection designs.This concrete does not explode in contrast to the usual, and therefore completely safe.

also used in modern construction aerated.Air blocks, the characteristics of which are more focused on the availability of construction in all climatic zones, almost all aerated bypass.The only advantage of the latter - a great strength.In addition to the production of aerated concrete costs several times higher.Besides, foam blocks more serious resistance to moisture, sincebubbles within the unit are isolated from each other.

Summing up, we can safely say: foam concrete blocks - an excellent modern material that can be used in all climates.High levels of strength can withstand heavy loads.In addition, the price of foam concrete blocks quite reasonable.
