AAC (Autoclaved aerated concrete) block 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.
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 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.

1. Light weight, can reduce the building's own weight and cost, and help improve the earthquake resistance of buildings
2. Good thermal insulation performance and low thermal conductivity
3. It has processability. It has the same processability as wood. It can be sawed, planed, drilled and nailed, which is conducive to construction and can be operated on site.
4. Strong pressure resistance
5. The aerated block is resistant to high temperature, and the compressive strength of the aerated concrete is slightly increased when the temperature is below 600 °C. When the temperature is around 600 °C, the compressive strength is close to the compressive strength at normal temperature, so The fire performance of aerated concrete for building materials meets national first-class fire protection standards.



Material dealing process
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.

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.

After slurry pouring into the mould, put the mould box into the curing room with 50~70℃. After 2-3 hours curing,the blocks become solid

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.

Finished product out of autoclave,with separting machine to separate layer by layer..

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.
