AAC(Aerated Autoclaved Concrete Block Machine line)introduce(1).  introductionAerated concrete brick (light brick ) is a light and porous building material. It has light keeping temperature cant burn and other advantages. it can be made into many kinds of bricks (for example 600×200×100,600×150×100, 600×300×200, 600×200×150 ), and they could be used in industrial buildings andmon buildings. they are more and more popular in the world .in the future, they will replace the Clay brickpletely.(2). Aerated concretemon  conceptionCommon concrete density is usuallykg/m3,but Aerated concrete are 500kg/m3,600kg/m3,700kg/ has not a big grain, its main use is silicon material (for example coal ash, sand, stone dust, and others ), through making the material small for example sand, they can be used directly if has enough degree of small (for example coal ash. Mixing calcium material lime cement water to a special slop, then add the aluminum dust and the additive.
