Scope of application

        Autoclaved aerated concrete blocks It is applicable to all kinds of infilled walls above the ground (± 0.000) and below the ground (except for walls with special requirements).

Autoclave Aerated concrete block It shall not be directly built on the floor or ground. C20 plain concrete wall pads with the same width as the wall thickness and no less than 0.2m in height should be poured at the root of the wall that is often subject to dry and wet replacement, such as the toilet, roof, external balcony, and the contact part between the air conditioner support plate and the masonry on the external wall; For other walls, autoclaved lime sand bricks should be used to build a wall mat with a height of not less than 0.2m at the root.

Autoclaved aerated concrete blocks shall not be used in the following parts:

1. The part of the building below ± 0.000 (except the interior infilled wall of the basement);

2. Parts that have been immersed in water for a long time or frequently replaced with dry and wet parts;

3. Environments subject to chemical corrosion, such as strong acid, strong alkali or high concentration of carbon dioxide;

4. The masonry surface is often in a high temperature environment above 80 ℃;

Autoclaved aerated concrete block is a kind of porous concrete product made from fly ash, lime, cement, gypsum, slag, etc. as the main raw materials, adding appropriate amount of air entraining agent, regulator, bubble stabilizer, through the process of batching, mixing, pouring, static stop, cutting and high-pressure steam curing.

Product features

The unit volume weight of autoclaved aerated concrete block is one third of that of clay brick, its thermal insulation function is 3-4 times that of clay brick, its sound insulation function is twice that of clay brick, its impermeability function is more than twice that of clay brick, and its fire resistance function is 6-8 times that of reinforced concrete. The masonry strength of the block is about 80% of its own strength (30% for red brick).

Product advantages

The construction characteristics of autoclaved aerated concrete block are also very good. It can not only produce various specifications in the factory, but also sawing, planing, drilling and nailing like wood. Because of its large volume, the construction speed is relatively fast, which can be used as filling materials for general construction.
