Specification :
Aerated Concrete Block Production
1. Introduce
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¡Ã200¡Ã100, 80¡Ã80¡Ã180, 240¡Ã115¡Ã53, 600¡Ã200¡Ã125). AAC blocks can be used for both industry buildings and common building. AAC blocks are getting more and more popular in the world. They have the trend to replace the clay brick completely in the future.
2. Areated concrete common conception
Common concrete density is usually 1600-2400kg/m3, 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. Finally there will become light brick . The porous rate is 70-80%.
3. Advantages:
Light weight
Areated concrete density is usually 400-700kg/m3, (according the market to produce), same as 1/3 of clay brick and 1/5 common concrete. So using the light brick can reduce the weight of the higher stories building, and also reduce the beam of roof and pillar pressure best. Then, it saves the material and cost. Also it is shock resistance.
Keeping warm
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 .
Use many kinds of materials, lowest waste
Main Material: coal ash, sand, waste mine material, coal gangue, stone dust and other silicon materials .
Save more land
when produce 10000 m3 light weight brick, will use 4200 Ton coal ash, and save coal ash using area 0.5 Mu,save burning clay brick 5 Mu.
