框架结构砌块填充墙容易产生一些质量通病 ,其表现一是墙体变形裂缝 ,二是抹灰层裂缝、空鼓。一、裂缝产生原因分析１．加气混凝土砌块的物理性能加气混凝土砌块的优点是自重轻 ,保温、隔声、耐火性能好 ,但吸水性强 ,导湿性、解湿性差 ,吸水率达７０ %～８０ % ,正常使用状态
Frame structure block filling wall prone to some quality problems, the performance of the first deformation of the wall cracks, the second is plaster cracks, hollowing. First, the cracks cause analysis 1. The physical properties of aerated concrete block aerated concrete block has the advantages of light weight, heat insulation, sound insulation, fire resistance, but strong water absorption, moisture conductivity, poor wettability, water absorption of 70% to 80%, normal status of use
