Recent innovations have led to the development of alkali-activated coating materials to replace organic coating and repairing materials for protecting and strengthening existing concrete structures, particularly for those under rigorous conditions. This chapter reports the laboratory and on-site works of examining the possibility of using alkali-activated metakaolin (AAM) as an inorganic coating material for marine concrete protection. As a new coating material, the basic engineering properties, including setting time, bond strength and durability, were investigated. The interface between AAM coating layer and OPC substrate under different curing conditions was examined, further providing valuable application guidance. The potential of developing fly ash and slag-based alkali-activated coatings are also discussed.
