Coarse aggregate ranging from 5-10mm are the most popular aggregate fraction used for the production of concrete and concrete structures, construction of roads, buildings and bridges etc. [4,5]. Aggregates control the unit weight, modulus of elasticity and dimensional stability of concrete because these properties depend on the physical characteristics of the aggregate. Aggregates that possess very high density, high compressive strength and high Young’s Modulus are considered fit for usage as coarse aggregate. This makes glass a potential material for usage as a coarse aggregate. Waste glasses are used as aggregates for concrete [7,8,9].
