Effect of Using Windows Waste Glass as Fine Aggregate on Some Properties of Concrete

Abstract

The main goal of this study is to investigate the effect of using waste glass (WG) on some mechanical properties of concrete at both fresh and hardened stages. In our study, we used local windows waste glass (WG) as partial replacement of fine aggregates with 0, 20, 25, and 30% percentages (by weight).The experimental results obtained from testing specimens prepared from concrete mixes with water/cement ratio equal to 0.5, showed that the optimum percentage of fine waste glass to be used within the concrete mix was 20%. At this percentage of replacement the compressive strength obtained at 28-days age was 39 MPa compared with 30.32 MPa for reference concrete mix.
