Abstract

Glass as aggregates in cement mortars not only improves the sustainability of the material, but also promotes waste management. In addition, the inclusion of supplementary cementitious materials (SCMs) further enhances material properties and sustainability. The mechanical performance of glass aggregate mortars was evaluated by means of compressive strength, whereas durability was assessed through alkali silica reaction, water immersion absorption and sorptivity, chloride ion permeations, and plastic and drying shrinkage. Investigations into the thermal properties of glass aggregate mortars were also completed. Glass aggregates were found to reduce compressive strength; however, binary and ternary blends of SCMs can offset the reduction in strength associated with the glass addition. Furthermore, glass aggregates are effective in improving chloride ion permeability, absorption, sorptivity, and shrinkage due to their inherently low absorption capacity. SCMs further improve the durability properties by enhancing the microstructural properties of the cementitious matrix. Moreover, SCMs are required to reduce detrimental ASR expansions to acceptable levels. Glass aggregate mortars also show promising thermal insulation performance.
