With technology cooperation with Germany company AAC CONCEPT, Our aac block machine inherits germany technology. So far we have 15 line of AAC block machine in Indonesia, 10 lines in india, 5 lines in Vietnam, 2 lines in Buma, 2 lines in Mongolia, 1 line in Kazakhstan, 1 one in Bulgaria
1. What is AAC?
AAC is a kind of light cellular silicate products. Main material based on Silicon materials ( sand, fly ash, gangue contains silicon)and Calcium(cement and lime), mix with foaming agent (Aluminium powder), after batching, mixing, pouring, pre-curing, cutting, stream(autocaled), and other process, finally, get this light weight concrete products...
2. Aerated concrete line, AAC production line Name meaning scope
AAC Block Machine also called light weight block making machine, is a new building area equipment, the name means the block should use autoclave to steam and become foam concrete, then used in light weight purpose.
3. Aerated concrete line, AAC production line Simple introduction
AAC block (light block) is the light and porous buidling material. The areated concrete block 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.
4. Aerated concrete line, AAC production 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%.
5. Aerated concrete line, AAC production line Advantages
1) light weight
Autoclave Aerated Concrete 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.
2) keeping temperature
Autoclave aerated concrete 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
3) autoclaved aerated concrete block Main Material
Coal ash sand waste mine material coal stonestone dust and other silicon materials.
4)Name scope
