with electro-migration of N,N'-dimethylaminoethanol and the electrochemical corrosion properties of the steel reinforcement was investigated through a comparative experiment, in which N,N'-dimethylaminoethanol was used as a corrosion inhibitor. The results show that the combined remediation technology can more quickly transport the inhibition groups into the steel reinforcement, and is similarly effective in removing chloride from the steel reinforcement, when compared with the natural diffusion of N, N'-dimethylaminoethanol and the single electrochemical chloride removal method. With the increase of the duration of current and the water-cement ratio, the amounts of nitrogen electro-migrated into the specimens and the chloride removed from the specimens increased. In addition, as the applied voltage increased, the amounts of nitrogen electro-migrated into the specimens and the chloride removed from the specimens initially increased, then remained steadily unchanged. After remediation, the steel reinforcement in the mortar exhibited a strong ability to maintain passivation.
