AAC (AUTOCLAVED AERATED CONCRETE) production line INTRODUCE

 

1. SIMPLE INTRODUCE

Aerated concrete brick (light brick ) is the 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× 100,80× 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. AAC PRODUCTION LINE 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 become the light brick, the porous
rate is 70-80%.

 

3. ADVANTAGES

light weight

AAC block 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.

Keeping temperature

AAC block 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.

Have many kinds material, have lowest waste

Main Material: coal ash sand waste mine material coal stones tone dust and other
silicon materials.
