Electrochemical Chloride Extraction Influence of Concrete Surface on Treatment

One bridge restoration technique available for reducing corrosion-induced concrete deterioration, which removes chloride ions (CI) while simultaneously re-alkalizing the concrete adjacent to the steel, is electrochemical chloride extraction (ECE). Studies have shown that ECE is capable of removing a significant portion of the CI from a reinforced concrete structure. The quantity of CI removed is dependent on numerous factors incl. quantity & spacing of reinforcing steel, applied, voltage, initial chloride concentration, etc. Investigations into chloride binding & competition between other ions as current carriers have clarified the problem mechan's. responsible for decreases in current efficiency with time during chloride removal.
