Abstract
This study aims to quantitatively estimate the geometric effect of steel bar on the resistivity measurement above reinforcement as a method of evaluating concrete resistivity. For this purpose, the geometric effect is evaluated by the resistivity estimation model (REM) that estimates the apparent resistivity above the reinforcement. This REM as a mathematical model reflects the resistivity of concrete and reinforcement, as well as the cover depth, the bar diameter, and electrode intervals. Based on this evaluation, this study proposes a geometric effect (GE) rate, which is the quantitative index determined by the geometric factors of reinforcement. It also experimentally examines the applicability of the apparent resistivity rate to diagnose the concrete resistivity. Based on the results of this study, the GE rate is expected to be useful for estimating the geometric effects of reinforcement.
