Abstract: Corrosion inhibitors can be introduced through concrete pores under the action of an electrical field. In this work, migration of corrosion inhibitors from the surface of the concrete, simultaneously to Electrochemical Chloride Removal (ECR), is considered. Two methods are proposed: 1) Connection of rebar as cathode for application of cationic inhibitors, and 2) Connection of rebar to an external cathode for application of anionic inhibitors.
Results show that the migration of inhibitors, simultaneously to ECR improves the efficiency of the treatment by removing more chlorides and enhancing the passivation process of the reinforcement after the treatment.
