SINOMA Best Quality/ aac Brick Making Mechinery/ aac Block Production Line
Advantage of AAC Block
1. Large size, however light weight
2. Light weight = saves foundation cost, helps the mason
3. High load-bearing strength
4. High durability = long life, impervious to rot or pest
5. Dimensional accuracy
6. High economy
7. Effortless handling, rapid construction
8. Best thermal insulation, 6 - 10 times better than regular dense concrete
9. Unsurpassed fire-resistance = life, property and insurance cost saver
10. Excellent sound absorption, ideal for the hospitality industry
11. Good workability, better than wood (can be sawn, drilled, nailed, milled at site)
12. Hurricane and earthquake resistance
13. Not rotting (contrary to timber)
14. Large size, however light weight
15. Light weight = saves foundation cost, helps the mason
16. High load-bearing strength
Raw Materials
The main materials are sand, cement, lime and aluminum powder.
1. Cement
425 # cement shall be acceptable.
2. Sand
The sand shall be requested as standard JC/T 622<sand for silicate building products>, The more quartz content, the better
result of production.
