Shenzhen Branch-Building Material Co., Ltd. is a franchise of the new energy-saving light wall materials - aerated concrete slab large enterprises. The company's products for use in civil and industrial construction Guangzhou precise filling brick factory, particularly high-rise building's exterior masonry frame structure Guangzhou precise filling brick wholesale, is building insulation, fire, earthquake, anti-leakage, embracing, energy Ideal wall materials. Aerated bricks characteristics and advantages: 1, light weight aerated concrete block generally weighs 500-700kg / m3 Guangzhou precise filling brick, clay brick is only equivalent to 1 / 4-1 / 5, 1/5 of ordinary concrete , it is a mild form of concrete. Weight than common brick concrete structure of the building reduced by more than 40%. 2, thermal conductivity, good thermal insulation properties of aerated concrete is 1/6, insulation performance is much better than ordinary concrete 240mm thick brick wall. 3, the seismic capacity of gas concrete capacity to impose light, good overall performance, when the earthquake inertia force is small, and therefore have a certain shock resistance.
