摘　　要：碱胶凝材料作为一种新型低碳建筑材料,以其优异的性能成为当前研究的热点领域之一。对近几年国内外对碱胶凝材料主要水化产物C-A-S-H与N-A-S-H结构组成特点及人工合成方法等方面的研究进展进行了综述,当前人工合成C-A-S-H与N-A-S-H的主要方法有溶胶-凝胶法、水热法和化学沉淀法等,合成所得的C-A-S-H与N-AS-H体系产物也与合成方法密切相关。通过总结目前已有的合成方法,对比分析了各种合成方法的优缺点,并提出了当前研究中一些亟待解决的问题和未来研究发展方向。Alkali-activated materials,as a new type of low-carbon building materials,have become one of the hot research fields with their excellent properties. The research progress in recent years in the structure composition and artificial synthesis methods of C-A-S-H and N-A-S-H in hydration products of alkali-activated materials are reviewed. The main methods of synthesizing C-A-S-H and N-A-S-H are solgel method,hydrothermal method and chemical precipitation method,and the synthesized C-A-S-H and N-A-S-H system products are also closely related to the synthesis methods. By summarizing the existing synthetic methods,the advantages and disadvantages of various synthetic methods are compared,and analyzed some problems to be solved in current research and future research directions.
