过去一般采用的干粘石饰面主要存在以下问题: (1)粘结砂浆需在外墙板混凝土浇灌后随即进行,工序衔接比较紧,否则易出现面层空鼓脱落现象。采用自然养护的构件,需在饰面层具有一定强度后才能浇水养护,这样,往往容易造成面层龟裂; The dry sticky stone used in the past generally has the following problems: (1) The adhesive mortar needs to be carried out immediately after the concrete of the outer wall panel is poured, and the process convergence is relatively tight. Otherwise, the looseness of the surface layer is likely to occur. The use of naturally-cured components requires watering and curing after the decorative layer has a certain degree of strength. This can easily cause surface cracking.
