– The aim of this paper was to investigate the passive corrosion control and active corrosion protective effect of the reinforced concrete structures by electrochemical chloride removal (ECR) method and inhibitors approach, respectively.
– The concentration of aggressive chloride ion distributed from the reinforcing steel to the surface of the concrete cover was analyzed during the ECR processes. Besides, the half-cell potential, the concrete resistance Rc, the polarization resistance Rp and the capacitance of double layer Cdl of the steel/concrete system were used to characterize the electrochemical performance of the concrete prisms.
– The effectiveness of ECR could be enhanced by increasing the amplitude of potential or prolonging the time. Inhibitor SBT-ZX(I) could successfully prevent the corrosion development of the reinforcing steel in concrete.
– The research provides the scientific basis for the practical application of ECR and inhibitors in the field.
