SEISMIC AREAS. Because of aerated concrete, light weight, seismic forces of the building is small Danzhou aerated concrete blocks, seismic favorable Orient aerated concrete blocks and brick masonry concrete block construction phase Biqionghaijia same building, Under the same seismic conditions, a difference of one degree of earthquake damage fortification level design, such as brick and concrete building in up to 7 degrees fortification, it will be affected by the destruction, but this time the aerated concrete building just up to 6 degrees fortification, it will not damaged. When the Haicheng earthquake, more than 30 blocks of porous concrete building exhibition harm slight increase in 1975 aerated concrete block, and brick building near the damage is serious; when the 1976 Tangshan earthquake, Beijing Baijiazhuang of a five-story plus aerated concrete load-bearing floor, the weight is only 700kg / m2, was in the seismic intensity of 6 degrees for the next strong case, no new cracks after the earthquake, but in four mixed residential structure at 50m, but the lower part of a large inclined cracks. Aerated concrete block production rich in raw materials, particularly the use of fly ash as raw material, both comprehensive utilization of industrial waste, environmental pollution, does not destroy farmland, but also to create a good social and economic benefits, is an alternative to conventional solid ideal brick wall materials, over the years by the national brick policies to support tax policy and environmental policy, and has broad market prospects. Hainan Jia aerated concrete block aerated concrete blocks _ _ preferred Branch-building materials provided by the Shenzhen Branch-Building Material Co., Ltd.
