- 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.
