Development of Lightweight Mortars Using Sustainable Low-Density Glass Aggregates from Secondary Raw Materials

In this study, different lightweight expanded glass aggregates (LEGAs) were produced from glass cullet and various carbonated wastes, through a thermal impact process. The effects of LEGA microstructure and morphology on both the adherence to the cement paste and the mechanical properties of mortars...
