This study presents the chloride ion transport behavior of mortar from accelerated chloride migration test (ACMT). The water/cement ratio of mortars is 0.45, and the five volume fractions of fine aggregates (0%, 15%, 30%, 50% and 60%) were evaluated. After stored under different environment temperatures (25°C, 40°C, 60°Cand 80°C), the chloride ion passing through specimens was carried out with ACMT. From the Nernest-Planck equation and modified Fick’s second law, test data could be calculate the chloride migration coefficient of non-steady-state and steady-state. For mortar structure, dilution and tortuosity effects are positive effect to resist the penetration of Chloride ion. On …
