 Sand / Flyash Autoclaved Aerated Concrete Block Machine Suppliers Introduce 

 1.Autoclaved aerated concrete block suppliers introduction

    Light weight brick is a light weight and porous building material. Cement, lime, slag, flyash, sand and foaming material as raw material, AAC is made by procedure of grinding, batching, pouring, cutting, curing and so on. It has light keeping temperature cant burn and other advantages.it can be made into many kinds of bricks(for        example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building.they are more and more popular in the world.in the future,they will replace the clay brick completely.

2.Aerated concrete common conception
     Common concrete density is usually 1600-2400kg/m3,but Aerated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain,main use 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.Make the aluminum dust and the special slop have a Chemical reflect.then produce Hydrogen to make the concrete slop to expanding or swell,foam.Next,put them into the curing room to concreting cutting steaming curing,last,there will bacome the light brick,the porous rate is 70-80%.

3.Autoclaved aerated concrete block suppliers Advantage

   1), Light weight
AAC porosity ratio reaches 70%-80% of whole block. Its density is 400-700kgs/m3, 1/3 of solid clay bricks, 1/5 of common concrete blocks.
    2), Good heat preservation
With a large number of pores inside, AAC has good heat preservation. Normally, AAC blocks with thickness of 200mm can preserve heat as well as those common solid clay blocks with thickness of 490mm.
   3), Good fire resistance without releasing harmful gas
Main materials for AAC are inorganic. It has features of keeping temperature, resisting fire and releasing no harmful gas. With good heat preservation to the steels, buildings made of AAC bricks can only be destroyed by surface when they are on fire.
