Five members all have serviced for the German YTong more than
20 years. Make the Dongyue technology research and development capabilities in the world's advanced level in the field of AAC.
1. Fly Ash/Sand ACC Block Machine simple introduce
AAC block (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: 600x200x100, 80x80x180, 240x115x53, 600x200x125), they could Be used industry building and common building. They are more and more popular in theWorld. In the future,
2. Fly Ash/Sand ACC Block Machine common conception
Common concrete density is usually 1600-2400kg/m3, but Areated concrete are 500kg/m3, 600kg/m3, 700kg/m3. 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. Fly Ash/Sand ACC Block Machine advantage
1). 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 ofThe 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
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.
