Experimental Study on Potential of Waste Glass Powder as Partial Replacement of Cement

Abstract

Cement producing industry is one of the major Carbon Dioxide radiating source other than deforestation and smoldering of fossil fuels. The unnatural weather change or in simple words Global Warming is brought on by the discharge of greenhouse gases, for example, CO2, to the atmosphere. Among all greenhouse gases, the contribution of Carbon Dioxide alone is about 65%. The cement producing industry all around the world contributes around 5% to 8% of total emission of Carbon Dioxide to atmosphere which increase the ultimate level of percentage of CO2 among greenhouse gases. So as to address such environmental effects associated with cement production, there is a need to create elective folios to make concrete. Endeavors have been made to utilize waste glass powder as fractional substitution of concrete. This examination incorporates the experimental investigation of properties of cement and concrete made with cement partially replaced with waste glass powder and after that contrast these with properties of conventional cement. All the experiments included in this project satisfy all the specifications recommended by Indian Standard Codes. The considered glass powder content is 10%, 20% and 30% by weight of cement. Test results shows insignificant effects on soundness and setting time of cement whereas use of glass powder up to 20% as cement replacement enhance the compressive and tensile strength of cement mortar as well as concrete.
