Electrochanical Chloride Extraction: Assessment of Benefits and Drawbacks
The use of electrochemical rehabilitation on chloride contaminated reinforced concrete structures has increased in recent years. One of these electrochemical methods is electrochemical chloride extraction, in which an electrical field is applied between the reinforcement and an external electrode. The method is applied to chloride-contaminated concrete where corrosion has not yet caused delamination or spalling of the concrete cover. The chloride is removed from the vicinity of the reinforcement within a short period of time (3 to 5 weeks) which makes it a cost effective alternative compared to traditional repair methods. This paper presents the latest developments in the field of chloride extraction. It explains its benefits and how to assess these, which is of particular importance when the efficiency of the method is to be evaluated. Questions have been raised about the occurrence of side effects such as spalling of concrete cover during chloride extraction, softening of the cement matrix and hydrogen embrittlement. This paper is aimed at the practitioner and, therefore, explains how to recognise and mitigate side effects through correct application of electrochemical chloride extraction.
