ABSTRACT
The monitoring of Electrochemical Chloride Extraction (ECE) of RC structures is crucial for both theoretical study and engineering practice, but the detection process is usually difficult to achieve. In this study, the ECE test was carried out and a method of synchronous monitoring ECE was explored. During the tests, the electrolyte of the ECE system was collected every day for daily chloride extraction monitoring. The outcomes show that the daily extraction content of chloride was high at the beginning (0 – 3 days) but declined and tended to be stable toward the end (after 3 days). The accumulated contents of chloride ions found in the electrolyte are compatible with the differences of total chloride ion contents measured before and after ECE (with a deviation of less than 4.7%), which proved the feasibility of the present method.
