AAC (Autoclave Aerated Concrete) is a new type building material where the raw materials are siliceous materials (flyash, sand, slag), calcareous materials (lime, cement and gypsum) and Aluminium powder.AAC product has been widely used in industrial and civil construction. AAC product can be divided into AAC block and AAC plate.

AAC technology is recommended for large scale production and consumption.

1.AAC block production line Introduction

Areated concrete brick (light brick ) is the light and porous buidling material. It has light keeping temperature cant burn and other advantages.it can be made into many kinds of bricks(for example:600×200×100,80×80×180,240×115×53,600×200×125),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.Areated concrete common  conception

Common concrete density is usually 1600-2400kg/m,but Areated 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.AAC block production line Advantages

     (1)light weight

     Areated concrete density is usually 400-700kg/m3,(according the market in produce),same as 1/3 of clay brick and  1/5 common concrete.So use the Light brick can reduce the weight of the build more,and also reduce the  beam of roof and pillar press best.then you can see,it can save the material and cost,it also fighting shaking.

    (2) keeping temperature

     It has many are porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as  1/4 or 1/5 of clay brick,so it is best  materials now in the world.There are many kinds material,have lowest waste.

    (3)Main Material:coal ash sand waste mine material coal stonestone dust and other silicon materials.
