摘要碱激发胶凝材料是一种节能环保建筑材料，其生产原材料来源广泛，耐久性存在较多不确定性。综述了碱激发胶凝材料在硫酸盐侵蚀、酸腐蚀、碳化及氯离子渗透条件下的耐久性研究成果，碱激发胶凝材料比普通硅酸盐水泥有更好的耐久性，原材料中的一些次要成分（如氧化镁）可能对碱激发胶凝材料的耐久性有一定的影响，通过细化碱激发胶凝材料孔隙结构和提高碱激发胶凝材料的密度，可以提高碱激发胶凝材料的抗腐蚀能力。

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.

Key words: alkali-activated cementitious materials durability microscopic mechanism microscopic analysis
