Abstract: The present investigation is to use the waste product from steel industry which is helpful in cement production if it is ground at a fineness of cement which also helps to reduce the carbon emission. Ground Granulated Blast Furnace Slag (GGBFS) is used as a mineral additive for concrete production and substitutes for cement, it behaves as a binder material along with cement.The optimum dosage of GGBFS as cementitious material is characterized by high compressive strength, low heat of hydration, resistance to chemical attack, better workability, good durability and cost-effective.This paper presents a laboratory investigation on optimum level of ground granulated blast-furnace slag on compressive strength of concrete.18 concrete mix sample were cast with water to cementitious material (w/cm) ratio 0.32 and 0.30 each; using GGBFS as partial replacement of cement from 0% to 50% at an interval of 10%. The specimens were cured for 28 days in potable water. The compressive strength of concrete is examined.The test results revealed that the compressive strength of concrete mixtures containing GGBFS increases as the amount of GGBFSincrease, upto certain limit. The optimum dosage of GGBFS is found at. This can be explained by the presence of unreacted GGBFS, behaves as a filler material in the paste and not as a binder.
