Evaluation Of Concrete Properties Using Ground Granulated Blast Furnace Slag

Traditionally, Ordinary Portland Cement concrete is used for making the civil structures. Portland cement can be replaced by Ground Granulated Blast Furnace Slag (GGBFS) which is a non-metallic and non-hazardous waste of the Iron industry. It is suitable for concrete mix and improves properties of concrete like compressive strength, workability etc. It has been seen that when cement is replaced with GGBFS compressive strength increases. However, this increase in compressive strength continues up to a certain percentage of replacement, but higher ratios gives lower compressive strength. The main objective of this research work is to determine the optimum replacement percentage which can be suitably used under the Indian conditions. To fulfil the objective various properties of concrete using GGBFS have been evaluated.
