Five different types of mortar mixtures (four mixtures with and one without glass aggregate) were produced. The fine aggregate was crushed granite aggregate. The glass sand content was approximately 5%, 10%, 15%, and 20% by mass of the total aggregate (granite + glass cullet), see Table 3. For reference, a base mix without glass …
