Effect of passivation on chloride concentration threshold of steel reinforcement corrosion

Purpose When concrete is manufactured, it can be instantaneously contaminated by chloride (Cl − ) ions or later by their intrusion from the environment. This work aims to study the electrochemical behavior of the passive layer formed on the reinforcing steel surface in the presence of the same Cl − ion concentration, with and without passivation time. This will, undoubtedly, affect the corrosion threshold values thereafter....
