Utilization and effects of various particle sizes of waste glass powder as partial replacement of cement in concrete

Abstract

This paper outlines the study undertaken regarding the usage and impacts of different particle sizes of Waste Glass Powder (WGP) when used as a partial replacement for cement in concrete. Through utilization WGP as a cement substitute, the mechanical and physical attributes, compressive strength and workability of concrete were assessed. The glass has been sieved from #200 sieve which has size of 74 µm and also sieved from #325 sieve which has size of 44 µm for a partial substitute of cement. To compare the WGP-replaced concrete's properties to reference specimens with no replacement at all, WGP was used to substitute 20% of the Portland cement in the concrete. The control samples were created following the IS-10262-2009 standard to reflect a goal of 30 Mpa, and cylindrical samples were fabricated, subjected to curing, and assessed for workability and compressive strength at intervals of 7, 14, 21, and 28 days after its casting. In conclusion, when the WGP particles are smaller, concrete becomes more workable and has a higher compressive strength then concrete with bigger particle sizes of WGP and control samples with no replacement. The findings of this study led to the conclusion that WGP's cementitious properties are acquired by its finer particles.
