Properties of Concrete Containing Recycled Glass Aggregates

The mean bulk densities measured for the concrete tested were, respectively, CONTR-2300 kg/m 3, CG10–2290 kg/m 3, CG30-2180 kg/m 3, CG50-1960 kg/m 3, and CG100-1660 kg/m 3. The results of this study show that this property was different for all concrete types. The density of concrete was lower, the more glass aggregate was used.
