In recent years, chloride ion stagnation has been reported in concrete with high chloride ion penetration resistance, even if the material age increases, the depth of chloride ion penetration does not change. It has been confirmed that most of the collected cores are not only at the chloride ion stop position, but also at the surface layer, and that this long-term chloride ion stagnation phenomenon has not been reported, which is a very valuable case. In order to properly predict chloride ion penetration, it is necessary to grasp and consider the above stagnation phenomenon. Therefore, the purpose of this study is to discuss the presumption of chloride ion penetration considering the stagnation of chloride ion penetration. In this study, the presumption of chloride ion penetration was studied considering chloride ion stagnation. The findings obtained in this study are shown below. In the case of low water bonding material ratio, chloride ion penetration is likely to stagnate in all test specimens of ordinary concrete, fly ash concrete and blast furnace slag concrete studied in this study. Based on the liquid water infiltration position determined by visual observation, a chloride ion infiltration presumption model was prepared for each cement species considering the effect of advection. In dense concrete structures with stagnant chloride ion penetration, it is confirmed that Fick's diffusion equation currently prescribed in the presentation. For blast furnace slag concrete with many coarse gaps and no chloride ion penetration stagnation, it is shown that it can be handled by using the chloride ion penetration estimation model of ordinary concrete.
