Product Description
Low Cost Autoclaved Aerated Concrete Block - AAC Block
AAC Introduction
AAC (Autoclave Aerated Concrete) is a new type building material where the raw materials are siliceous materials (fly-ash, sand, slag), calcareous materials (lime, cement and gypsum) and Aluminium powder.
AAC product has been widely used in industrial and civil construction. AAC product can be divided into AAC block and AAC plate.

AAC Block is short for Autoclaved Aerated Concrete Block. which is also called  ALC Block. It is lightweight and loadbearing and made from silica sand, cement, lime and gypsum.
The block may be well used as both  external wall (exterior wall) and internal wall (interior wall). It has been widely used for various buildings, such as villas, apartments, schools, factories, shopping mall, hospitals, etc...  We have been exporting the blocks to many foreign countrie for some years with good reputation.

 Process flow
(1)  raw materials: sand, cement, fly ash, slag, gypsum, shale, most of industrial waste can be used as block raw materials, which improves a lot on environment.
(2),  Measuring, batching and casting section
Slurry, cement agents, gypsum and aluminum go into high-speed stirring mixer after automatic measuring respectively, and then bubbles inside green body will be sorted out by vibration rods. The whole system is full-automatically controlled by PLC to guarantee the high efficiency and precision of procedure running.
(3)Static curing and Cutting
Stable and still curing can avoid damage to internal structure when the gas is and expanding inside the green block. High efficient and fluent cutting machine and table tilt machine are the key parts to the hexahedral cutting.
(4) Autoclaving and Final Product Process
Green body gets final strength and performance via autoclaving. our newly developed separating and packing system can not only promote qualification rate but also solve the difficulty in separating blocks and wall panels at the same time.

Features & Advantages of lightweight concrete block 
1. LightweightAerated concrete density is usually 400-900 kg/m3(according to the market), which is 1/3 of clay block and 1/5 of common concrete. 
2.FireproofMost of the major raw materials is inorganic materials, so it has good fire resistance,and do not emit harmful gases when meet fire
3.Sound insulationAs the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties
4.Thermal InsulationThermal conductivity is 0.9-0.22 W/(MK), which is 1/4 of clay bricks.
5.Anti-seismicThe same building structure, improve the two seismic than the brick level
