Abstract: In this study the electrochemical technique is applied to accelerate chloride ion migration in cement-based material to estimate its permeability. Specimens with six fine aggregate volume fractions were cast and tested. For all test series, the chloride concentrations both in anode and cathode cells as well as the electrical current were simultaneously monitored in the accelerated chloride migration test. The chloride migration rates of anode and chloride cells were used to assess the permeability of cement-based materials. A good correlation was observed between the chloride migration rate of anode cell and cathode cell. And, a good correlation was also observed between the chloride concentration in anode cell, the chloride concentration in cathode cell and charge passed obtained from the accelerated chloride migration test.
