在施工中,由于原料或配比、浇捣及养护等原因,往往会发生梁柱等构件的混凝土强度达不到设计标号的质量问题,给混凝土结构工程带来隐患。如果把这部分构件拆除,不仅会造成人力物力的很大浪费,而且还将大大地拖延工期,直接影响到建设项目的经济 In the construction, due to the reasons such as raw materials or proportioning, pouring and maintenance, the quality problems such as the strength of the concrete of beams and columns cannot reach the design label, and this will bring hidden troubles to the concrete structure engineering. If this part of the components is dismantled, it will not only cause a huge waste of manpower and material resources, but it will also greatly delay the construction period, directly affecting the economy of the construction project.
