Demand for natural sand in concrete is increasing day by day since the available sand cannot meet the rising demand of construction sector. This paper reports the experimental study undertaken to investigate the influence of partial replacement of cement with Ground Granulated Blast Furnace Slag(GGBFS) in concrete containing quarry dust as fine aggregate. The cement was replaced by 10%, 20%, 30%, 40% and 50% of GGBFS and tests were conducted to determine the optimum level of replacement of GGBFS in quarry dust concrete. The specimens were subjected to compressive strength, split tensile strength, flexural strength, and bond strength tests at 7days, 28days, 56days, 90days and 150 days. The resistance to corrosion is evaluated based on the performance of the concrete for the penetration of chloride ions by means of impressed voltage technique in saline medium and Gravimetric weight loss method. Results herein reveal that an increase in slag proportion increases the strength properties and decreases the rate and amount of corrosion of reinforcement and among the various percentages of replacement 40% is found to be optimum with better strength and corrosion resistance properties.
