加气混凝土从七十年代开始在我国建筑业中推广应用以来,以其能取代粘土砖,减少毁田烧砖,利用工业废料以及节能、保温、吸声等性能,显示出优越性,受到各方面的重视。但由于加气混凝土干燥收缩较大,持续的吸水性及强度较低等特点,在做墙体时,为抹灰装修带来一定困难,易造成灰层空鼓,脱落等缺陷,为此施工部门采用在加气混凝土基层上钉钢板网抹灰或涂刷107胶的方法以保证抹灰的 Since the aerated concrete was promoted and applied in China’s construction industry in the 1970s, it has been able to replace clay bricks, reduce the destruction of land and bricks, use industrial wastes, as well as energy-saving, heat preservation, sound absorption and other properties, showing superiority, Aspects of attention. However, due to the large dry shrinkage of air-entrained concrete, and its low water absorption and strength, it is difficult for plastering decoration when it is used as a wall, and it is easy to cause defects such as hollowing and falling of the gray layer. The department adopted a method of nailing steel nets or applying 107 glue to the aerated concrete base to ensure the plastering.
