Abstract: 
This paper presents a new method for measuring the chloride migration rate in cement-based materials from the accelerated chloride migration test. In steady state, a good correlation was observed between the chloride concentration in anode cell and charge passed. Also, the average current that calculated from the slop of Q-time curve in the steady state condition correlates linearly with the chloride migration rate. Therefore, the chloride migration rate can be determined from the slop of the linear portion of Q-time curve to avoid the sampling and analyzing chlorides during the accelerated chloride migration test.
