This paper is investigate the effect of high blaine blast furnace slag powder(HBS) on the durability of high performance concrete. The use of HBS requires an increase in dosages of superplasticizer by as much as 0.1~0.2 % and makes the concrete satisfied the target slump flow and air contents. An increase in HBS resulted in an increase of compressive strength due to latent hydraulic reaction. Coefficient of chloride diffusion, sulfate resistance and freeze thaw test results showed improved performance when HBS was incorporated. the use of HBS decreased peak temperature based on semi adiabatic temperature test. hence, it is confirmed that the addition of HBS improved strength and durability.
