Glass Wastes as Coarse Aggregate in Concrete

Waste glass is a major component of the solid waste stream in many countries. It can be found in many forms, including container glass, flat glass such as windows, bulb glass and cathode ray tube glass. At present, although a small proportion of the post-consumer glass has been recycled and reused, a significant proportion, which is about 84% of the waste glass generated, is sent to landfill. Glass is a 100% recyclable material with high performances and unique aesthetic properties which make it suitable for wide-spread uses. Glassis widely used in our lives through manufacturedtract products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps save of energy. Th e increasing awareness of glass recycling speeds up inspections on the use of waste glass with different forms invarious fields. One of its significant contributions is to the construction field where the waste glass was reused for concrete production. The application of glass in architectural concrete still needs improvement. Laboratory experiments were conducted in the SHIATS to further explore the use of waste glass as coarse aggregates replacement in concrete. The study indicated that Waste glass can effectively be used as coarse aggregate replaceme nt (upto 50%) without substantial change in strength.
