Fly ash AAC Sand AAC Aerated Autoclave Concrete Brick Machine Line (AAC PLANT)
Block feature: Light weight, Durable, Fireproof, Good anti-shake, Keeping temperature, Easy use and build quickly
1. Introduction of Fly ash AAC Sand AAC Aerated Autoclave Concrete Brick Machine Line
Areated concrete brick (light brick ) is the light and porous buidling material. It has light weight keeping temperature cant burn and other advantages. It can be made into many kinds of bricks(for sample: 600× 200× 100, 80× 80× 180, 240× 115× 53, 600× 200× 125), they could be used industry building and common building.
2. Fly ash AAC Sand AAC Aerated Autoclave Concrete Brick Machine Line 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, last, there will bacome the light brick, the porous rate is 70-80%.
3. Advantages of Fly ash AAC Sand AAC Aerated Autoclave Concrete Brick Machine Line
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.
It has many 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. Also many kinds raw material, have lowest waste
