Autoclaved Aerated Concrete Brick Making Production line
1. Introduction:
AAC is a kind of light cellular silicate products. Main material based on Silicon materials (sand, fly ash, gangue contains silicon) and Calcium(cement and lime), mix with foaming agent (Aluminium powder), after batching, mixing, pouring, pre-curing, cutting, steam (autoclaved), and other process, finally, get this light weight concrete products.
2. Advantage:
Aerated concrete brick is a revolutionary material offering an unique combination of high durability and strength, low weight, excellent heat insulation, fire resistant, noise absorption,unprecedented build ability and superior ecological green features. In China, AAC is one of the light wall materials which was popularized and applied at the earliest and the most widely.
3. Classification: AAC Classification: in general, it can be classified according to the types of raw materials, manufacture process and functions. Based on the shape of AAC products, it can be divided into: AAC blocks and AAC panels. It can be made into many kinds of bricks (for example: 600*200*100mm, 600*150*100mm, 600*300*200mm, 600*200*150mm), they could be used industry building and common building. They are more and more popular in the world.

1. Raw materials processing
Put the fly ash or sand into the ball mill to mill via the conveyor belt, after milling, put the slurry into the slurry storage
tank by slurry pump.
2. Batching, mixing and casting
The lime, cement will convey by conveyor to the dry powder measure scale to scale separately. The slurry convey by slurry pump
then to the automatic scale;the power and slurry put into the mixer,pouring into the mould.
3. Curing process
After slurry pouring into the mould, put the mould box into the curing room with 50~70ºC. After 1-2 hours curing,the blocks become solid.
4. Cutting
Using reversal crane carry the mould and block to demould on cutting cart. The cutting cart will take the block to level cutting machine,vertical cutting, two sides cutting,and remove the top waste material.
5. Autoclaved
Finished cutting using semi-product crane carry to the front of autoclave grouped, hoisting machine or dragger will drag steam trolley into autoclave to steam,it need 8-11 hours.
6. Finished block dealing
Finished product out of autoclave,with separating machine to separate layer by layer.
7. Packing
Using finished block carry hanger clamp the finished product to package line on wooden pallets,after package, then by forklift
transport the finished products to piled yard according to specifications to stack.
AAC is a kind of light cellular silicate products.
Main material based on Silicon materials (sand, fly ash, gangue contains silicon) and Calcium (cement and lime), mix with foaming agent (Aluminium powder), after batching, mixing, pouring, pre-curing, cutting, steam (autoclaved), and other process, finally, get this light weight concrete products.
1. Lightweight:
Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
2. Sound insulation:Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
3. Insulation:As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
4. Fireproof:Most of the major raw materials is inorganic materials, so it has good fire resistance,
and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
5. Durability:Material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable after ten years.
6. Shortcut:It has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction. 7. Economy: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
