水泥砂浆地面面层产生不规则的收缩裂缝、空鼓以及起砂等缺陷,是工程施工中常见的质量通病,出现这类现象的主要原因是没有严格按照施工及验收规范和施工工艺标准的要求去操作。例如选择使用的水泥不符合要求、水灰比过大、基层清理不干净、养护不良及过早受荷扰动等诸多因素。因此,我们应在施工中对各个环节严格把关,尽量避免出现这些质量问题。 The surface layer of cement mortar produces irregular shrinkage cracks, empty drums, and sanding defects. It is a common quality problem in engineering construction. The main reason for this phenomenon is that the requirements of construction and acceptance standards and construction technology standards have not been strictly met. Go to operation. For example, the choice of cement used does not meet the requirements, water-cement ratio is too large, the grass-roots cleaning is not clean, poor maintenance and premature loading and other factors. Therefore, we should strictly control all aspects of construction and try to avoid these quality problems.
