Description

NACE 01101 – Electrochemical Chloride Extraction from Steel Reinforced Concrete – A State-of-the-Art Report

The purpose of this NACE technical committee report is to present state-of-the-art informationon electrochemical chloride extraction (ECE) from conventionally reinforcedconcrete surfaces. Included are discussions of common industry practices used by designengineers to control corrosion of reinforcing steel in portland cement concretestructures through the application of ECE.

This report is intended for use by engineers attempting to protect corroding reinforcedconcrete structures by the use of electrochemical treatment techniques. The informationpresented in this report is limited to ECE for atmospherically exposed reinforcedconcrete and is not applicable to prestressed or post-tensioned elements or concretecontaining epoxy-coated reinforcing steel, galvanized steel, or other coated or nonferrousreinforcement.

This report, focusing on electrochemical chloride extraction, is Part I of a two-part series.Part II is intended to focus on the realkalization of carbonated concrete structures.
