Glass Waste in Concrete: Effect on Workability and Compressive Strength

Abstract

Major challengers due to growing construction are unbearable burden on environment and rapid depletion of respective natural resources. Any construction activities require more or less natural material like aggregates which cause rapid depletion of the same due to high consumption. On the other hand production of one ton cement is responsible for emission of 0.9 ton CO2. For sustainable development use of waste material in construction may be a key point. In the present investigation an attempted is made to explore the possibility of using waste glass as partial replacement of cement and fine aggregate in concrete. Waste sheet glass kept in abundance was crushed and sieve. The fraction passing through 150 micron IS sieve was used as partial replacement of cement (5% - 25%). Whereas fraction passed through IS 4.75 mm sieve was used as partial replacement of natural fine aggregate (10% - 70%). Result showed that glass waste can be used as partial replacement of cement and fine aggregate individually. It is also revealed that compressive strength of concrete made with glass waste was more than the referral conventional concrete at all the replacement levels of cement and natural fine aggregate.
