Repairing tunnelsis an essential part of infrastructure upkeep that guarantees commuter safety and the durability of the tunnels. A variety of materials, including cement-based ones like concrete, shotcrete, and mortar, are needed for tunnel repairs. Yet, the hunt for substitute materials has been sparked by the negative environmental effect of cement manufacturing and the accompanying expenses. It has been suggested that geopolymers, a type of materials that develop from the reaction between aluminosilicate minerals and alkali activators, might replace cement-based materialsin tunnel restoration. This review paper focuses on evaluating the potential of geopolymers towards applications for tunnel mending because they are a new material with many possible uses. © 2025. The Author(s).
