Abstract

Abstract: The paper presents the experimental results of the influence of relative humidity (RH), temperature, fly ash content and chloride concentration on the relationship between concrete resistivity and the corrosion level of steel bar in concrete. The results show that the concrete resistivity decreases with the increase of corrosion level of steel bar under the same RH and temperature. The concrete resistivity decreases with the increase of RH and temperature, and the relationship between concrete resistivity and RH (temperature) is established. The concrete resistivity increases with the increase of fly ash content when the concrete cover thickness and the corrosion level of steel bar are the same, while it decreases with the increase of chloride concentration. The relationship between concrete resistivity and the corrosion level of steel bar in concrete with different chloride concentration (fly ash content) is established.
