Abstract: Abstract: In this study the electrochemical technique is applied to accelerate chloride ion migration in concrete to determine the chloride ions in anode cell. This paper presents a new method for determining the chloride migration rate in concrete from steady state migration test by measuring the electrical current. The plain ordinary Portland cement concrete and concrete containing different type of mineral admixtures (fly ash and slag) with w/b ratios of 0.35, 0.45, 0.55, and 0.65 were used.For a given charge passed in steady state, the current corresponding to the given charge passed was correlated with the chloride migration rate. The results for all mixtures show that the chloride migration rate and the current corresponding to a given charge passed in steady state is linearly correlated.
