| Abstract |
Mineral admixture is generally known to densify internal matrix through pozzolan reaction and potential hydraulic reaction. Also it blocks penetration of degradation factors from external. But proper curing is necessary for targeting performance on using mineral admixture. In this study, author evaluates the effect of binder and curing condition on the chloride ion transport characteristics under using blast furnace and fly ash through chloride ion penetration resistance and diffusion coefficient of concrete. As a result of the study, the conditions using blast furnace slag and fly ash, large difference in chlorine ion transport characteristics was observed depending on the curing condition compared with using only cement conditions. Especially, the condition of using blast furnace slag and fly ash in air and carbonation curing condition significantly decreased the chloride ion permeability and the chloride ion diffusion coefficient compared with under water curing conditions. |
