在施工现场要严格控制混凝土试块的留置,混凝土试块强度试验,是控制混凝土结构承载力性能较直的手段。承载力性能涉及使用者的生命、财产安全,是混凝土结构质量控制的重点。施工现场应根据规范及强度试块的作用,应留置三种混凝土强度试块:第一种为混凝土标准养护试块;第二种为用于确定施工期间混凝土强度的同条件养护试块;第三种为用于结构实体检验的同条件养护试块。
In the construction site, strict control of the placement of the concrete test block and the strength test of the concrete test block are the means to control the bearing capacity of the concrete structure. The bearing capacity performance relates to the user’s life and property safety and is the key to the quality control of concrete structures. Three kinds of concrete strength test blocks shall be placed on the site according to the specifications and strength test blocks: the first one is a concrete standard curing test block; the second one is a same-condition maintenance test block used to determine the concrete strength during construction; Three are the same condition maintenance test blocks used for structural entity testing.
