摘　　要：地聚合物是一种新型绿色建筑材料,具备优异的机械强度、耐高温等性能,此外地聚合物其原料来源广泛,可由含有硅铝的工业固体废弃物制得。因此,地聚合物作为绿色建筑材料有性能优异、工艺简单、能耗低、碳排放低等优点,具有广阔的应用前景。然而,当地聚合物应用于水环境中时,其在水体中的抗侵蚀性能需要进一步综合分析。在综述地聚合物制备工艺和合成机理的基础上,分析了地聚合物的原料和养护方式对其抗侵蚀性的影响,进一步阐述了地聚合物的三维网络结构和抗衡阳离子的耐侵蚀性,最后提出了地聚合物在水体中抗侵蚀性的研究展望。Geopolymer is a new green building material with excellent mechanical strength and high temperature resistance.In addition,geopolymer has a wide range of raw materials and can be made from industrial solid wastes containing silicon and aluminum.Therefore,geopolymer,as a green building material,has many advantages,such as excellent performance,simple process,low energy consumption and low carbon emission,and has broad application prospects.However,when geopolymer is used in water environment,its anti-erosion performance in water needs further comprehensive analysis.Here,based on summarizing the preparation technology and synthesis mechanism of geopolymer,this paper analyzes the effects of raw materials and curing methods of geopolymer on its corrosion resistance,and then determines the erosion resistance of its three-dimensional network structure and counter cations.Finally,the research prospect of geopolymer's erosion resistance in water is put forward.
