In this study, fundamental properties of high strength concrete containing blast furnace slag are investigated analyzed according to CBS-Dust replacement rate. As the CBS-Dust replacement rate increased, air content, fluidity and strength decreased, but concrete with 5~10 % of CBS-Dust showed excellent compressive strength in its early age. Therefore, 5~10 % substitution of CBS-Dust on high strength concrete containing blast furnace slag will have a positive effect on reducing waste disposal cost and improving the strength.
