The Impact of Combination of Al2O3 Nanoparticles with Fly Ash and Glass Powder in Concrete

Telem Chingkheinganba and Balwinder Lallotra

Abstract

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%.
