Study on the effect of Waste Glass Powder as a Pozzolanic material in concrete

Concrete is a construction material composed of Cement, fine aggregate, coarse aggregate, and water with or without admixtures. The concrete industry is one of the heaviest consumers of natural resources due to which sustainability of concrete industry is under threat. The environmental and economic concern is the greatest challenge the concrete industry is confronting. Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and the combustion of fossil fuels. The global warming is induced by the emission of greenhouse gases, such as CO2, to the atmosphere. Concrete mixtures were produced, tested and compared in terms of Compressive Strength, Split Tensile Strength and Flexural Strength of the conventional concrete at a period of 28 days. The role of GLP provides for considerable value-added utilization of waste glass in concrete and significant decreases in the output of greenhouse gases by the cement industry. This paper presents the feasibility of the substitution of waste glass powder for cement to achieve economical and environmentally friendly construction material.
