Abstract
To improve the durability of concrete structure, we usually consider the reduction of water-cement ratio, the increase of concrete cover depth and the use of mineral admixtures. The use of admixtures make concrete more durable and tighten against water in recent papers so it is needed to study more about the relationship between the admixtures and the chloride ion diffusion. Therefore we analyzed the correlation between chloride ion diffusion and physical properties such as compressive strength, void ratio, air permeability of the concrete, and tried to use them as fundamental data for analyzing chloride ion diffusion mechanism of the concrete mixed with mineral admixtures.
Keywords
