A survey of the literature on the relationship between concrete resistivity and corrosion rate

The movement of ions through the concrete microstructure helps to regulate the process of reinforcement corrosion in concrete. Ions are charged, and the electrical resistivity of a substance determines its capacity to withstand charge transfer. As a result, a link between the corrosion process of steel buried in concrete and the electrical resistivity of concrete might be anticipated. The study on the connection between corrosion rate and concrete resistivity is reviewed in this article. In general, the parameters have an inverse proportional relationship. However, the connection between corrosion rate and resistivity varies across research, and no one relationship can be established. To resolve the discrepancy, the paper examines and analyzes the impact of variables such as the experimental setup, concrete mix design, and corrosion cause.
