The manufacture of cement is another source of carbon dioxide emissions. The possibility of using glass in concrete to reduce waste disposal costs is fascinating. Glass is a material that can be recycled and used continuously without changing its chemical makeup. The current study examines the impact of nano alumina (Al₂O₃) and fly ash replacing cement and glass powder replacing sand mixed and examined mechanical characteristics, microscopic examination, and non-destructive test. Nano alumina is applied in concentrations of 0.5%, 1%, 1.5%, and 2% as a part replacement for ordinary Portland cement (OPC). Fly ash replaced cement at a constant amount of 15% and glass powder at a fixed proportion of 15% for sand. The findings showed that it achieves its maximum strength at a nano alumina substitution rate of 1.5%.
