摘要:

由于实际结构中的混凝土与标准养护试块之间有很大差异,所以传统检测方法中用标准养护试块抗压强度来确定结构中混凝土的强度等级是不恰当的.为寻找最佳的能代表结构中混凝土强度的强度,本试验对郑州市两个厂家的混凝土分别进行标养强度、同条件养护强度及结构实体取芯强度的测定,分析三者之间的相互关系及造成其差异的因素,得出三种强度的相关关系式,从而找出了适合郑州市检测结构实体混凝土强度与混凝土强度等级判定标准之间的切合点.

Abstract:

Due to the great difference between the concrete in the actual structure and the standard curing test block, it is inappropriate to use the compressive strength of the standard curing test block to determine the strength grade of the concrete in the structure in the traditional detection method. In order to find the best strength that can represent the strength of concrete in the structure, this test measured the standard curing strength, curing strength under the same conditions and the coring strength of the structural entity of the concrete of the two manufacturers in Zhengzhou, analyzed the correlation between the three and the factors causing their differences, and obtained the correlation between the three strengths, so as to find out the convergence point suitable for detecting the concrete strength of the structure and the concrete strength grade judgment standard suitable for Zhengzhou City.
