Utilization of Recycled Glass Waste as Partial Replacement of Fine Aggregate in Concrete

Concrete is mainly used as construction material and its demand is increasing day by day. The main intention of utilizing recycled glass waste as partial replacement for fine aggregate in concrete is to promote sustainability by reducing the environmental impact of waste disposal and the consumption of natural resources. Using recycled materials can lower construction costs by reducing the need for traditional, often more expensive, aggregates. In this project, waste glass powder is used as partial replacement of sand in M2O grade concrete. Concrete cubes are casted with 0%, 5%, 10%, 15%, 20% and up to the maximum percentage where the strength get maximum with replacing fine aggregate. The compressive strength and tensile strength of these mixes was tested at different curing ages 7 days, 14days, and 28days to assess the performance of the concrete containing recycled glass powder. The strength of values of concrete are comparable with that of the nominal mix. Additionally, the study examines the potential environmental benefits of reducing the consumption of natural resources and mitigating waste disposal issues through the utilization of recycled glass waste.
