Product Description

AAC Blocks Advantages:

AAC (autoclaved aerated concrete) block is made mainly of sand / flyash,cement,aluminium,lime,gypsum, under the
high temperature ,high pressure and steam curing . It's a new type building materials ,has its incomparable advantages ;

1. Lightweight: Porosity achieve 70% to 85%, volume density is generally 500-900kg/m3, as 1/5 of general concrete brick, the 1/4of clay brick, the 1/3 of hollow brick, and similar to the  wood which can float in water. It can reduce building weight, reduction in the cost of integrated building, moreover, prolong building's life.

2. 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 100 mm walls can reach to 4 hours fire resistance, 300mm thick up wall can reach to 9 hours fire resistance.

3. Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 100mm thick wall up to 41 db.

4. 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.

5. Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.

6. Anti-seismic: The same building structure, improve the two seismic than the brick level.

7. Green: Manufacturing, transportation, all use the process of non-pollution, to protect arable land, saving energy, is one kind of a green building material.



Main Process Flow of AAC Block Production Line:

1. 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 under a certain temperature and time, the block would reach a certain hardness and prepare for cutting;
5. Tilting hoister would turn over 90 degrees of mould;
6. Then open the mould and separate it from block. And take the block with side plate to the cutting cart;
7.  The horizontal cutting machine cuts blocks from both sides.
8.  Then the vertical cutting;
9. After cutting, the block is hanged to curing carts with side plate by semi-finished product hoister;
10. Grouping the carts and put them into autoclaves;
11. Curing the blocks under certain temperature and pressure;
12. Carry the finished product out of autoclave by the winch.
13. The finished product hoister take the finished product to finished blocks area;
14. The side plate return back through side plate roller;
15. Side plate would be organized with open mould for the next circle.
