Throughout the world, the most widely used construction material is concrete. It is the second most consumed substance on the earth after water. As concrete being used for construction of most of the buildings, bridges etc., it has been labeled as the backbone to the infrastructure development of the nation. It is commonly made by mixing Portland cement with sand, crushed rock and water. It is very clear that among all the components, aggregate and water is largely available material in India at very low cost. As cement is comparatively high cost it would be advisable to use other locally available industrial and agricultural waste material to replace the cement partially. Ground Granulated Blast-furnace Slag (GGBS) is a non-metallic and non-hazardous waste material of the Iron Industry. Therefore, the minimization of this waste material without a harmful effect on nature has a vital importance. The present work focused on the utilization of GGBS in concrete which can be suitably used under the Indian conditions. For this purpose, the various tests on properties of green and hardened concrete have been performed. The properties of green concrete have been analyzed by workability of concrete in terms of slump value whereas the properties of hardened concrete have been analyzed in terms of mechanical and physical properties of concrete. The mechanical properties of hardened concrete include the compressive strength, flexural strength and split tensile strength whereas physical properties include the dry & moist density and water absorption of hardened concrete. On the basis of present work, we found that GGBS in concrete improves workability, compressive strength, flexural strength, split tensile strength and decreases the density & water absorption characteristics of hardened concrete. As a result, the cost of concrete decreases. Also, GGBS leads to the significant reduction in the quantity of cement which enables the reduction in CO2 emission and reduction in energy consumption in production of cement.
