Waste products, agricultural waste, and other natural elements are currently the focus of scientific attention as they seek to create technologies that may be used as building raw materials. On the other hand, recycling helps build a cleaner, safer environment while also boosting the economy. The purpose of this research is to find out how much stronger concrete becomes when various glass particles are used in place of cement in M25 and M30 concrete mixes. Glass bottles and other bottles that end up in landfills are a byproduct of people's daily water use and other unsanitary practices. Land filling broken glass is an environmentally harmful and unsustainable practice since the material does not biodegrade. Glass is mostly composed of silica. The primary objective of this research is to examine the potential effects of using glass powder as a partial cement substitute in two distinct concrete grades, M25 and M30, at varying percentages (5%, 10%, 15%, 20% & 25% of the cement weight). On days 7, 14, and 28, we compared the findings to those of normal concrete by testing the strength and split tensile strength. Key Words: Cement, glass powder, natural sand, coarse aggregate, compressive strength, cracking tensile strength.
