Influence of Waste Glass Powder on Properties of Concrete: Utilizing Waste Glass Powder for Improved Concrete Performance

Abstract

In today’s world, civil infrastructure plays a veryimportant role in development of any country. Cement is the main constituentused in construction industry. As the cement production is increasing,consequently CO2 content is also increasing in environment. Soefforts are being done to develop some alternative ways for concrete productionusing Waste material. Waste glass powder (WGP) is one such alternative. Thenon-biodegradability of waste glass powder makes it a harmful pollutant ofenvironment, so its use as supplementary compendious material (SCM) will alsohelp in solving glass related environmental problems. The present work consists of using WGP in differentproportions (2%, 6%, 10%, 14%, 18%, 22%, 26% and 30%) by weight. The concretesamples were tested for compressive and flexural strength and it was concludedthat waste glass powder of size less than 100 micron can be used as partialreplacement of cement. The compressive strength as well as the flexuralstrength was maximum at 18% partial replacement of cement with waste glasspowder by weight.
