在当今整个社会的建设工程项目中,混凝土结构的房屋建筑在现代工程施工中占有很重要的地位,因此对混凝土的要求也是越来越高,不管是在它的外观,还是内在,都严格要求工程质量。根据现在房屋损坏情况来看,混凝土裂缝的建筑工程质量问题很是严重,会降低结构的整体稳定性和抗震性能,但它的有害程度是可以控制的,本文结合多年的工作实践,对预防混凝土裂缝的发生原因进行进行了总结,并提出了相关的预防措施。 In today’s society as a whole, construction projects of concrete structures occupy a very important position in the construction of modern projects, so the requirements on concrete are also getting higher and higher, both in its appearance and its inherent requirements. Engineering Quality. According to the current situation of damaged houses, the quality of concrete construction cracks is very serious, which will reduce the overall stability and seismic performance of the structure, but its harmfulness can be controlled. In this paper, with many years of practice, The causes of cracks were summarized, and the related preventive measures were put forward.
