Abstract
An electrochemical process for the removal of chloride ions from reinforced concrete includes passing a direct current between (i) an anode in electrical contact with the adherent coating containing a water retaining adhesive material, and an aqueous electrolyte applied to an external surface of the concrete and (ii) a cathode which is located internally in the concrete. According to the process, chloride ions are caused to migrate to the anode. In order to reduce the production of chlorine gas, the coating contains, as a chlorine scavenger, solid calcium hydroxide or barium hydroxide, or mixtures thereof. The chlorine scavenger is most preferably present in an amount of at least 8%, and more preferably 20 to 50%, by weight based on the dry weight of the water retaining material.
