Abstract |
This study aims to evaluate the effect of reinforcement according to the measurement location in the measuring of electrical resistivity in concrete structures. The Apparent Resistivity rate (AR rate) based on the Resistivity Estimation Model (REM) was used for quantitative analysis of the measurement position and the angle of an electrode in the apparent resistivity measurement. It was confirmed that the measurement sensitivity of the apparent resistivity varies depending on the above conditions. In order to examine the applicability of the AR rate, the concrete resistivity was estimated from the apparent resistivity measured in a reinforced concrete specimen. This concrete resistivity was applied to the AR rate to calculate the estimated apparent resistivity. As a result, it was found that although the internal conditions of the concrete had an influence on the measurement results, the estimated apparent resistivity well represented the trend of the measured apparent resistivity.
