摘要：

Electrochemical chloride extraction(ECE), as a novel rehabilitation technology on the chloride contaminated structures, can be used to repel the harmful chloride ions in reinforced concrete structure out from the vicinity of the rebar to the surface of concrete and repassivate the rebar through the applied electric field. In this paper, recent research progress at home and abroad on ECE were reviewed. The basic mechanism of ECE, device selection and determination of parameters, factors influencing the ECE performance and the effect of ECE on macro and micro performance of concrete were systematically introduced. Meanwhile some aspects for the further studies were proposed combined with the current status of research on ECE. ©, 2015, China Water Power Press. All right reserved.
