利用炉渣制作空心砌块代替粘土砖、加气混凝土砌块已广泛用于多层、高层框架结构的填充墙中,节约了大量土地资源。但是,因构造不合理和施工方法不当等原因,会使建筑物墙体出现不同程度的裂缝。针对裂缝产生的原因,我们在施工中不断总结、摸索,克服了炉渣砌块墙体抹灰面裂缝的质量通病。具体作法如下。1.严把原材料质量关。当地建设行政主管部门、建筑工程质量监督站,每年应对炉渣砌块生产企业进行3～4次抽样检查,对砌块 Hollow blocks made of slag instead of clay brick, aerated concrete block has been widely used in multi-storey, high-rise frame structure filled wall, saving a lot of land resources. However, because of the unreasonable construction and improper construction methods, cracks will appear in the walls of buildings. In response to the causes of cracks, we constantly summarize and explore during construction to overcome the common quality of the cracks in the plaster surface of the slag block wall. Specific practices are as follows. 1. strict quality control of raw materials. The local administrative department of construction, construction quality supervision station, slag block production enterprises every year to conduct 3 to 4 times the sampling inspection, the block
