Abstract Alkali-activated cementitious material is an energy-saving and environmentally friendly building material. Its raw materials are widely sourced and its durability is uncertain. The research results on the durability of alkali-activated cementitious materials under sulfate attack, acid corrosion, carbonization and chloride ion penetration are reviewed. Alkali-activated cementitious materials have better durability than ordinary Portland cement. Some secondary components in raw materials (such as magnesium oxide) may have unknown effects on the durability of alkali-activated cementitious materials. The corrosion resistance of alkali-activated cementitious materials can be improved by refining the pore structure of alkali-activated cementitious materials and increasing the density of alkali-activated cementitious materials.
