Advantages of AAC block
Light weight
Aerate concrete desity is usually 300-800kg/m3,(according the market ti produce),same as 1/3 of clay bbrick and 1/5 common comcrete,So use the light brick can reduce the weight of 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 hearting coefficient is 0.9-0.22w/(mk),the same as 1/4 or 1/5 of clay brick,so it is best material now in the world.
Save more land
When produce 1000m3 light weight brick,will use 4200Ton coal ash,and save coal ash using area 05 mu,save burning clay brick 5mu.
Process flow of AAC plant
We take different technics to produce AAC according to the raw material , quality and equipments technical features. Usually, we first grind the sand and slag together some water into slurry, then put some lime , cement , gypsum , foaming agent and foam stabilizer into the slurry, mix them and cast the mixture into the mould . After static foaming and hardening , cut the cake into blocks with the size we want . The cut cakes are then sent into the autoclave , after steam curing , we will get the porous lightweight AAC products
1. First, 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
