城市建设的飞速发展,为予拌砼提供了广阔的市场。使用预拌砼不仅有利于改善现场施工环境,节约施工用地,减轻工人劳动程度,减少材料浪费,加快施工速度,而且有利于保证砼质量的稳定,实现建筑工业化。但予拌砼在我省起步较晚,应用还不够成熟,质量问题时有发生,突出表现的是砼裂缝问题,轻则影响砼的观感质量,重则影响其使用功能,甚至危及结构安全。由此常常引发 The rapid development of urban construction has provided a vast market for the mix. The use of pre-mixed concrete will not only help improve the on-site construction environment, save construction land, reduce the labor level of workers, reduce material waste, and speed up the construction, but also help ensure the stability of concrete quality and realize industrialization of buildings. However, in the province of Fujian Province, the late start, the application is not mature enough, quality problems occur from time to time, highlighting the performance of cracks, but affect the quality of the flaws, affect the use of functions, and even jeopardize the structural safety. This often causes
