砼陶粒空心砌块填充墙抹灰层裂缝的原因分析与预防措施

Analysis about the causes of flaws in infill-wall floated coat of concrete sintered aggregate building block and prevention measures for flaws.

钢筋砼结构为减轻楼面荷载,填充墙多采用轻质砌块材料,诸如加气混凝土砌块、空心粘土砖、砼陶粒空心砌块等等。上述材料砌筑时稍有不慎,极易造成抹灰层裂缝,形成质量通病。主要对目前国内砼陶粒空心砌块作为填充墙,其抹灰层易出现裂缝这一通病的原因进行分析,以及在施工过程中如何预防。

In Reinforced concrete structures, many kinds of lightweight block are being used for filler walls, such as air-entrainment concrete block, hollow clay brick, ceramsite hollow block, etc. The materials mentioned above must be used carefully, or it is very likely to result in crack of plaster, which is the common problem of quality. The paper analyzes the reasons which contribute to the problem that cracks are usually found in the plaster of filler walls which are made of ceramsite hollow block.
