【摘要】 硅烷偶联剂（SCA）作为含有不同反应性官能团的有机硅化合物，能有效提高水泥、混凝土与地聚合物的诸多技术性能，改善基体存在的缺陷。系统综述了硅烷偶联剂掺入水泥基材料与地聚合物中对其水化过程、微观结构与主要技术性能等所产生的影响，总结分析硅烷偶联剂与两者之间的作用机理，阐明了硅烷偶联剂在两种材料中的研究前景。综合分析后认为，硅烷偶联剂能提高水泥混凝土、地聚合物与其他材料之间的相容性与协同性，在改善水泥基材料与地聚合物的性能方面也表现出优异的效果，但可能伴随着少量的负面效应。针对硅烷偶联剂水泥基材料与地聚合物的改性结果，采用不同的硅烷类型、使用方式或新技术等以减轻或消除负面效应的产生是每个研究者值得思考的问题。更多还原

【Abstract】 As an organosilicon compound containing two different reactive groups,silane coupling agent can effectively improve the technical properties of cement,concrete and geopolymers and improve the defects of the matrix.The effects of silane coupling agents on the hydration process,microstructure and main technical properties of cement-based materials and geopolymers were systematically reviewed,and the interaction mechanism between silane coupling agents and them was summarized and analyzed.The research prospect of silane coupling agent in two kinds of materials is expounded.After comprehensive analysis,it is considered that silane coupling agent can improve the compatibility and coordination between cement concrete,geopolymer and other materials,and it also shows excellent effect in improving the properties of cement-based materials and geopolymers,but it may be accompanied by a small amount of negative effects.According to the modification results of cement-based materials and geopolymers modified by silane coupling agents,it is worth thinking about using different silane types,usage methods or new technologies to reduce or eliminate the negative effects.更多还原
