摘要
Electrochemical chloride extraction (ECE) is an effective method for rehabilitating reinforced concrete structure damaged by the corrosion process. The understanding of the chloride transference in reinforced concrete structure during ECE process is essential for further exploring the ECE mechanism and propose the mathematical model. In this paper, we used an embeddable chloride probe and chemical titration analysis for analyzing the chloride content in different depth of the concrete structure during the ECE process. Moreover, the decomposition of bound chlorides during the ECE process was also investigated.
