2.Reliable and stable maintenance

      Autoclaved aerated concrete (AAC) concrete and panel production line, 20000-300000 m3 per year. AAC plant contains the cutting machine, ball mill, autoclave, crusher and so on. The autoclave aerated concrete plant simple name is AAC equipment, Production Process of Aerated Concrete According to the category and quality of raw material, and the features of equipment, the aerated concrete can be manufactured in different processes. Generally, add water to ash, silica sand or slag and crush them into slurry; Then add powdery lime, cement of right amount, plaster, vesicant, foam stabilizer, and mix and pour it to mould frame; After curing, foaming and hardening, cut it into blocks and boards in different specifications; Finally, transport it into pressure steamer with steam-curing cart, and get the light cellular concrete after steam-curing with high temperature and pressure. Process Flow of an Annual Output 50, 000 m3---200, 000 m3 Aerated Concrete Steam-Curing Production
Production Engineering of China AAC plant :
1. Firstly, dose and match measured raw materials
2. After distributing, feed raw material into pouring mixer to make slurry
3. Through thoroughly mixing, the slurry is poured to mould
4. After pre-curing with a certain temperature & time, the block would reach certain hardness prepare for cutting 5. Tilting hoister would turn over 90 degree of mould
6. Then open the mould & separate it from block, take the block with side plate with cutting cart
7. The block then be cut through the cutter firstly of two vertical sides of block
8. Secondly the horizontal cutting
9. Finally the vertical cutting
10. After cutting, the block is hanged to trolley with side plate by semi-finished product hoister
11. Organizing the cut blocks and put them into autoclave
12. Hardening the blocks under certain temperature and pressure
13. Take finished products out of autoclave
14. The finished product hoister takes the finished product to stock shield
15. Packed for loading
16. The side plate return back by side plate roller
17. Side plate would be organized with open mould
18. Clean the mould and preparing for next pouring
19. Steel bars processing line for slab production Construction Benefits
  1.Sound proof   AAC wall has an excellent sound Transmission class (STC) ,rating of 44. Result: Virtually Soundproof  Interiors!   2.Thermal Insulation   It has highest thermal rating in the industry….R30! Thus provides well insulated interiors, keeping out warm air in summer and cold air in winters.AAC reduces Air conditioning cost by 30%.    3.Earthquake Resistant   Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to earthquake forces. Regions of high seismic activity like Japan exclusively use AAC. It has been proven to withstand wind loads of category 5 tropical storms.   4.Floor Space Area   Use of thinner blocks (6" instead of 9" exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.   5.Cost saving   Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving.Being 8 times the size of a clay brick, AAC wall construction    involves 1/3 the joints, thus an overall mortar saving up to 66%.   Its automatic manufacturing process gives AAC an exceptional dimensional accuracy & smooth surfaces, eliminating need of three-coat plaster walls and allows for a final 6 mm skim coat (putty/POP).   6.Fire Resistant   Best in class fire rating of 4 hours. The melting point of AAC is over 1600 ºc, more than twice the typical temperature in a building fire of 650 ºc.   7.Pest ResistantTermites hate AAC! Being made of inorganic minerals, it does not promote growth of molds.   8.Water Barrier    Its structure does not allow for capillary action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives.   strength to weight ratio, higher than even M150 concrete and far exceeds the Indian Building code requirements.   9.Energy Efficient   AAC is 100% Green Building Material & is a walling material of choice in LEED certified buildings (ITC centre, the highest rated Green Building has been built using AAC).AAC is most energy & resource efficient in the sense that it uses least amount of energy & material per m³ of product.Unlike brick manufacturing process which uses previous toplayer agricultural soil, AAC uses FlyAsh (65% of its weight), thus provides the most constructive solution to the nation’s flyash utilization problem.
