A comprehensive review of the durability and microstructural properties of alkali-activated materials (AAMs) made with waste glass as a precursor is presented in this paper. AAMs are potentially sustainable alternatives that can be utilized to replace Portland cement (PC) materials due to the total elimination of PC as the binder. The traditional precursors utilized in the production of AAMs are fly ash and slag. However, other waste products such as glass powder (GP) can be applied as a precursor in the production of AAMs. Due to the limited research and application of waste glass as a precursor in AAMs, a thorough analysis was made to investigate current studies where the durability and microstructural characteristics of AAMs made with waste glass were evaluated. The durability properties explored are permeability properties, shrinkage, alkali-silica reaction and resistance to aggressive environments. Microstructural properties discussions were also made to support the corresponding physical properties of GP-based AAMs.
