The development of infrastructures involves the use of many natural resources resulting in their depletion. The production of the cement causes many problems like emission of carbon-di-oxide gas to the atmosphere can be reduced by the replacement of cement with GGBS. Similarly, the replacement of SS as a fine aggregate also enables to eliminate the problems associated with production of aggregates.This study aims to generate specific experimental data on the potential use of ground granulated blast furnace slag (GGBS) as a cement replacement as well as scrap slag (SS) as a fine aggregate replacement in concrete. This study analyses the mechanical strength for compressive strength, split tensile strength and flexural strength were conducted to find the optimum usage of alternative material GGBS with proportions of 15%, 25% and 30% of total weight of concrete and SS as fine aggregate in GGBS incorporated concrete with varying proportions of 4%, 8%, 12%, 16% and 20% of total weight of concrete. Also durability tests of sulphate , chloride resistance and corrosion test were performed. The experimental results have been shown that SS is a non- hazardous industrial by- product from steel making units. Optimum percentage of GGBS as binder was found to be 25% in M25 grade concrete. From the research study, the optimum percentage of SS as fine aggregate in optimum GGBS incorporated concrete was found as the concrete made with 12% replacement of fine aggregate with SS. The duration of concrete exposure in sodium sulphate solution increases the weight loss increases and compressive strength decreases. As the duration of concrete exposure in hydrochloric acid solution increases the weight loss is less affected and the compressive strength decreases.
