2022 4 22 To address the cement/concrete industry's environmental and economic challenges, Malik et al. 2013 used waste glass as a partial replacement for fine aggregates sand in concrete. Several samples were made by replacing sand with glass contents of 10%, 20%, 30%, and 40% by weight in M 25 grade concrete.The samples were tested for compressibility,
