Main raw materials of AAC are siliceous material (sand, fly ash and Silicon tailings) and Calcium materials (lime and cement) mixed with foaming agent (aluminum powder). It is the product of light porous silicate through the following processes: batching, mixing, pouring, hardening, cutting, autoclaving and curing etc. Because of large amount of well-distributed tiny pores after foaming, it is named autoclaved aerated concrete.

Production process
1,Raw material preparation
1. Dose and match measured raw materials;
2. After distributing, feed raw material into pouring mixer to make slurry.
2,Reinforcement processing
3.Automatic circulation system for cage assembly frame
4.Mesh cage anti-corrosion drying room
5.Automatic warp and weft rib full wire strip welding machine
6.Cage assembly frame shuttle
7.Mesh cage rigid connection welding machine
8Net cage anti-corrosion spreader
3,Pouring pre-uperation
9. Through thoroughly mixing, the slurry is poured to mould; ,
10. After pre-curing under a certain temperature and time, the block would reach a certain hardness and prepare for cutting;
4,Cutting section
11. Tilting hoister would turn over 90 degrees of mould;
12. Then open the mould and separate it from block. And take the block with side plate to the cutting cart;
13. The horizontal cutting machine cuts blocks from both sides.
14. Then the vertical cutting;
5,Marshalling steaming
15. After cutting, the block is hanged to curing carts with side plate by semi-finished product hoister;
16. Grouping the carts and put them into autoclaves;
17. Curing the blocks under certain temperature and pressure;
18. Carry the finished product out of autoclave by the ferry cart
6,Finished product packaging
19. The finished product hoister take the finished product to finished blocks area;
20. The side plate return back through side plate roller;
21. Side plate would be organized with open mould for the next circle.
