Abstract:
Although light gauge steel and foamed concrete composite wall has the advantages of light weight, heat insulation, sound insulation and fire resistance, wall shrinkage and cracking are often found. In order to improve its crack resistance, tests of the foamed concrete shrinkage, wall unit with added structure detail measures and construction measures of wall were conducted. The results indicated that, on the premise that construction is not affected, the reduction of water cement ratio and the increase of fiber and lightweight aggregate are effective measures to reduce foamed concrete shrinkage; by fixing wire meshes on both sides of light gauge steel wall, using coated curing and prolonging the curing time the wall cracks can be effectively controlled.
