This study focusses on understanding the influence of processed granulated blast furnace (PGBS) slag on fresh and hardened state properties of concrete. Nowadays, metallurgical slags are being explored as alternative materials to natural virgin aggregates in concrete. Before using any such material in concrete, it is important to understand its influence on properties of concrete. In this study an attempt has been made to use granulated blast furnace slag from a local steel plant as a substitute to natural sand in normal concrete. The study mainly focusses on understanding the influence of different replacement ratios and suitability of slag replacement ratios higher than 50% in normal concrete. The blast furnace slag used in the present study was processed using a vertical shaft impactor to modify the particle shape and enhance its aggregate properties. The replacement was done at 50%, 75% and 100% by mass of natural sand in the concrete mix. The concrete properties such as slump, compressive strength, splitting tensile strength and flexural strength, were studied at all the replacement ratios.
