This paper Investigate that the effect of the concretes containing mineral admixture(fly ash, ground granulated blast furnace slag, silica fume, meta-kaolin) on the resistance properties to chloride Ion invasion by the Rapid Chloride Migration Test(RCMT) and the long tenn Immersing test The purposed testing procedure was applied to the concrete mixed mineral admixtures for 3~4 replacement ratios under W/B ratios ranged from 0.40 to 055 For the RCMT, Tang and Nilsson's method was used to estimate the migration coefficient of chloride ion
The results could be summarized as follows,
① The addition of mineral admixtures by mass enhanced the resistance of the concrete to chloride penetration compared With the plain concrete.
② The optimal replacement ratios of admixture had a limitation for each admixtures.
③ Chloride migration coefficient estimated at 28 days by the RCMT had a well establishment
With the chloride diffusion coefficient estimated by the immersion test at 330days.
