Concrete industry is one of the largest consumers of natural resources due to which sustainability of concrete industry is under threat. The environmental and economic concern is the biggest challenge concrete industry is facing. In this paper, the issues of environmental and economic concern are addressed by the use of waste glass powder as partial replacement of cement in concrete. Cement was replaced by waste glass powder as 0% to 40% in increment of 5% in M20. The concrete specimens were

The results concluded the permissibility of using waste glass powder as partial replacement of cement at 20% by weight. www.iosrjournals.org 18 | Page Mix M20(1:1.34:3.2) w/c:0.45 replace by glass powder + 0.03% glass fibre  Flexure test: Mix M20(1:1.34:3.2) w/c:0.45 replace by glass powder Mix M20(1:1.34:3.2) w/c:0.45 replace by glass powder + 0.03% glass fibre
