Abstract This study developed a methodology for quantifying the corrosion parameters such as corrosion potential, corrosion current density and Tafel slopes for rebar in simulated pore solutions and mortar with realistic rebar conditions. We quantitatively investigated the impact of depassivation duration, chloride concentration, carbonation, and relative humidity on these parameters. Specifically, in partially saturated mortar, it was observed that the critical chloride content lacked a distinct threshold. The degree of depassivation, as indicated by shifts in corrosion parameters due to chloride ions and carbonation, was influenced by humidity.
Highlights A critical review of rebar corrosion parameters in solution and concrete. A non-submerged two-step potentiodynamic test method on rebar corrosion in mortar. Long-term effect of chloride-induced depassivation in simulated pore solutions. Measurements of corrosion parameters in simulated pore solutions and mortar. Effects of chloride, carbonation, and relative humidity on the corrosion parameters.
