地聚合物是指采用天然矿物或固体废弃物及人工硅铝化合物为原料，在碱性条件下通过矿物缩聚而形成的三维网状聚合胶凝材料。地聚合物独特的结构与性质使其在固化/稳定化重金属方面具有明显优势，近年来已成为国内外研究热点。针对地聚合物固化/稳定化重金属，重点阐述了影响地聚合物固化/稳定化重金属效果的重要因素，并综述了国内外研究者对地聚合物固化/稳定化重金属作用机制的研究成果。
Geopolymer is a kind of inorganic polymer cementitious material,which has a 3D network of silico-a-luminate structures.Geopolymeric materials could be synthesized from calcined clays,industrial waste or other alumino-silicate containing source materials under alkaline conditions.Geopolymer had been a hot point in im-mobilizing heavy metals in the recent years due to its unique structure and properties.Important factors that in-fluence the solidification/stabilization of geopolymers were emphasized introduced,as well as current status of the researches on mechanism of immobilizing heavy metals are reviewed.
