Autoclaved aerated concrete block AAC (ALC)
Autoclaved aerated concrete block AAC (ALC) (Executive standard: GB11968-2006)
Raw material:Quartz sand, cement, lime, water, gas generator, regulator.
Product number:B03, B04, B05, B06.
Product advantages:
Light weight, thermal insulation, sound insulation, fire prevention, good processability and quick construction. The bulk density is 1/4 of ordinary concrete, 1/3 of clay brick, lighter than water, and comparable to wood; thermal insulation is 6 times that of glass, 3 times of clay brick, 10 times that of ordinary concrete; sound insulation performance is 2 times the clay brick; the fire resistance is 6-8 times that of reinforced concrete; it can also be sawed, planed, drilled and nailed like wood. Because of its large volume, the construction speed is fast.
Application range:
Frame structures and steel structures such as houses, public buildings, and factory buildings. Can be used as interior walls, exterior walls, fire insulation walls.
Jingbo environmental protection material product advantages:
1. Replacement of raw materials
Silica sand is used instead of fly ash to make siliceous material. The strength of the block is high, and the anti-seepage and anti-cracking, heat-insulating and sound-insulating properties are good.
2. Automated industrial products
The production line adopts automatic equipment, and the product scale is accurate, the error is small, and it can be continuously produced in large quantities.
3. thin seam masonry process
The thin seam masonry process is used, and the binder is used for masonry. The gray joint is only 3mm, and the wall surface is flat. It can be painted without using only putty, and it is not easy to crack.
