摘要：

The main objective of this study was to evaluate the correlation between chloride migration rate and the charge passed rate for concrete. The electrochemical technique is applied to accelerate chloride ion migration in concrete to obtain chloride migration rate and the charge passed rate. In this study, the plain cement concrete and concrete containing different types of mineral admixtures (fly ash and slag) with w/b ratios of 0.35, 0.45, 0.55, and 0.65 were used. A good correlation between chloride migration rate and charge passed rate obtained from the accelerated chloride migration test in the steady state was found. In order to avoid sampling and analyzing chlorides during the migration test, the procedure of determining the chloride migration rate by measuring the charge passed seems valid.
