Aerated concrete block is a lightweight porous, thermal insulation, fire performance, nailing, sawing, planing and new building materials with certain seismic capacity. Back in the early 1930s, China began the production of such products, and is widely used in the Shanghai International Hotel Tower, Shanghai, Fuzhou building, the People's Bank of China Tower, and high-low-rise buildings. Is an excellent new building materials. And has environmental advantages. Product advantages: 1, the general weight of the light weight aerated concrete blocks of 500-700 kg / cubic meter, the equivalent of clay brick and sand-lime brick 1/4-1/3, 1/5 of the ordinary concrete, concrete in a mild form, suitable for high-rise buildings, infill walls and load-bearing walls of low-rise buildings. The use of this material, you can make the dead weight of the entire building more than 40% reduction in weight than ordinary brick buildings. Construction to reduce weight, the destructive earthquake, so greatly enhance the seismic capacity of the building. 2, good thermal insulation performance of aerated concrete thermal conductivity is generally 0.11-0.18 kcal / m 0 hours 0 degrees, only tablets of adobe bricks and sand-lime brick 1/4-1/5 (tablets adobe The thermal conductivity of 0.4-0.58 kcal / m o hours o degrees; thermal conductivity of sand-lime brick 0.528 kcal / m o hours o degrees) for about 1/6 of the normal concrete. Practice has proved that: 20 cm thick aerated concrete wall insulation effect is equivalent to 49 cm thick clay brick wall insulation effect, the insulation performance is much better than the 24 cm brick walls. This greatly thinning the thickness of the wall, they expand the effective use of space in the building, saving building materials thickness, improve construction efficiency, reduce project cost, reducing the weight of buildings. 3, high strength by experiment, aerated concrete block compressive strength greater than 25 kg / sq cm, equivalent to No. 125, compressive strength of clay brick and sand-lime brick. 4, the seismic performance Fortunately, a magnitude 7.8 earthquake in Tangshan Feng South, visits, according to post-earthquake, aerated concrete building only emerging a few cracks in brick buildings full almost collapsed, so that these two Building, not far from the same structure but different materials of construction in stark contrast. The analysts believe that this is because of the aerated concrete light density, good overall performance when the earthquake inertia force, so the seismic capacity. This will be in terms of the for our multi earthquake country is very beneficial. 5, good processing properties of aerated concrete has good processing performance. Can saw and planing can nail can milling can drill. Reinforced and can be added in the manufacturing process. Bring a lot of convenience and flexibility to the construction.
