Concrete is a highly costly and widely used material in modern building, where cement serves as the primary component. We produce a billion tonnes of concrete annually. In other words, cement manufacture contributes to global warming by producing an excessive amount of CO2. India is mostly affected by the pollution issue. Utilizing industrial by products has gained popularity as an environmentally friendly alternative to disposal as people are becoming more conscious of the environment and its potentially dangerous impacts. This study uses industrial by products including ground granulated blast furnace slag (GGBS), by product of the steel industry, and silica fume (SF), by product of the smelting process in the silicon and ferrosilicon industries. In the current investigation, different amounts of industrial by products, including GGBS up to 50% and SF up to 20%, were employed to prepare the concrete. After a 28-day curing period, the compressive strength of hardened concrete was assessed. To measure degradation in a harsh environment, concrete was then subjected to salty water (NACL) and MgSO4 for 90 and 180 days, respectively. In order to evaluate the strength deterioration of concrete, non-destructive testing (NDT) was also used. Positive study findings showed that concrete with the best waste replacement improves physical properties.
