The purpose of this technical committee report is to present state-of-the-art information on electrochemical realkalization (ER) for conventionally reinforced concrete structures. Included are discussions of common industry practices used by design engineers to control corrosion of reinforcing steel in portland cement concrete structures through the application of ER. This report is intended for use by engineers attempting to protect corroding reinforced concrete structures by use of electrochemical treatment techniques. The information presented in this report is limited to ER for atmospherically exposed reinforced concrete and is not applicable to prestressed or post-tensioned elements or concrete containing epoxy-coated reinforcing steel, galvanized, or other coated or nonferrous reinforcement.
