Audited Supplier 1. AAC(Autoclaved Aerated Concrete) Block Making Machine Line
(1) Introduction
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*100mm, 600*150*100mm, 600*300*200mm, 600*200*150mm), 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)Aerated concrete common conception
Common concrete density is usually 1600-2400kgs/m3, but aerated concrete are 500kgs/m3, 600kgs/m3, 700kgs/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 the light brick. The porous rate is 70-80%.
(3)Advantages
Light weight
Aerated concrete density is usually 400-700kgs/m3(according the market production), 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
It has many are porous, the delivery heating coefficient is 0.9-0.22W/(m.k), 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: Silicon Sand/Fly ash 65-70%, Cement 12-15%, Lime powder 12-15%, Gypsum 3-5%, Aluminum 0.5kg/m3 AAC block.
