Highlights The current efficiency was not constant, and it was affected by the current density. The oxidation of the hydroxyl lowered the current efficiency in the early corrosion stages. The natural corrosion after cracking made the current efficiency exceed 100%. The higher the current density, the less was the influence of the natural corrosion.
Abstract The impressing current technique with different current densities is widely adopted for investigating the deterioration problems caused by the reinforcement corrosion. Additionally, the theoretical mass loss of reinforcement is obtained using Faraday’s Law with the assumption that all of the impressed charge participates in the corrosion reaction. In this study, the accelerated corrosion of the reinforcements with different current densities was non-destructively traced by the X-ray micro-computed tomography (XCT). The results indicated that the current efficiency was not constant during the corrosion process. The evolution of the current efficiency was influenced by the current density.
