The study provides details regarding exploratory examination on the suitability of squashed glass as partially replaced for fine total in solid generation. With the use of waste glasses available around the world at low costs, the use of Waste Glass seems to offer the best short term solutions for rising river bed and demand. The global warming is caused by the emission of greenhouse gases, such as CO2, to the atmosphere. Among the greenhouse gases, CO2 contributes about 65% of global warming. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmosphere. In order to address environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. Efforts have been made in the concrete industry to use waste glass as partial replacement of coarse or fine aggregates and cement. In this study, finely powdered waste glasses are used as a partial replacement of fine aggregate in concrete and compared it with conventional concrete. The objective of this project work is to study the effects of using waste glass as partial replacement for fine aggregate. Different concrete mixes were prepared by varying the amounts of crushed waste glass. The waste glass was used to replace fine aggregate in the proportions of 10% , 20% , 30% . The study indicated that waste glass can effectively be used as fine aggregate replacement without substantial change in strength.
