The purpose of this study is to explore the time dependant behaviors of chloride ions adsorption with cement hydrates, focused on its mechanism. AFt phase and CH phase were not able to absorb chloride ion, however, C-S-H phase and AFm phase had a significant chloride adsorption capacity. Based on the results, this study suggested theoretical approach to depict chloride adsorption behavior with elapsed time of C-S-H phase and AFm phase effectively. AFm phase showed a slow chemical adsorption in 40 days, while C-S-H phase showed binding behavior with 3 stages including the stage of instantaneous physical adsorption other stages.
