Abstract

In order to solve the problem of inaccurate detection of reinforced concrete protective layer thickness in engineering, this paper studied and formed a reasonable and perfect method and calibration procedure for the detection of reinforced concrete protective layer thickness in highway and water transportation engineering by using the analysis of influencing factors. The results show that the accuracy of measuring the protective layer thickness of reinforced concrete in practical engineering can be effectively improved. The production of standard instrument calibration specimens can be saved, and the testing process can be standardized.
