Abstract: This paper shows the chloride diffusivity of mortar and concrete with ground granulated blast furnace slag and blast furnace slag sand from the result of submergence test for 3 years in salt water. When the ground granulated blast furnace slag is used as a part of binder, the chloride diffusivity of mortar and concrete becomes small. When blast furnace slag sand is used as fine aggregate, the chloride diffusivity of mortar and concrete also becomes small. By using both ground granulated blast furnace slag and blast furnace slag sand, its effect will be higher. Especially, mortar with both ground granulated blast furnace slag and blast furnace slag sand has low chloride ion diffusivity because the chloride ion distribution soaked for 3 years is the same as that soaked for 0.3 years. Regardless of the use of blast furnace slag, the chloride ion diffusivity of concrete cured by steam is larger than that of concrete cured in water.
