回弹-取芯法在结构实体混凝土强度检验中的应用

Application of Rebound-coring Method in Strength Inspection of Structural Solid Concrete

在详细阐述施工评定中的混凝土强度指标与结构计算中的强度指标之间关系的基础上,深入分析了回弹-取芯法的理论基础及优缺点。结合近年来深圳地区混凝土实体强度检验结果及国内典型的混凝土质量事故的反思,说明回弹-取芯法在结构实体混凝土强度检验中的地位,并指出了其在应用中的技术要点,补充了混凝土结构施工质量验收规范中关于回弹-取芯法失败后的处理程序。

Based on the detailed description of the relationship between the concrete strength index in the construction evaluation and the strength index in structural calculation,the theoretical basis,advantages and disadvantages of rebound-coring method are deeply analyzed.Combined with the concrete solid strength test results in Shenzhen in recent years and the reflection of typical concrete quality accidents in China,the importance of rebound-coring method in structural solid concrete strength test is explained,and the technical points in its application are also pointed out.The treatment procedure after the failure of rebound-coring method in the code for acceptance of construction quality of concrete structures is supplemented.
