［摘要］采用三种不同的硅烷单体，利用有机-无机杂化技术制备硅烷-硅溶胶杂化材料，并针对杂化材料的类型、杂化比等因素对水泥基材料力学性能、防水性能、抗氯离子侵蚀性能的影响进行较为系统的研究。结果表明，通过有机-无机杂化反应，可制备出性能稳定的硅烷-硅溶胶杂化材料，且随着烷基碳数的增加，杂化材料的稳定性有所提高。硅烷中添加硅溶胶一定程度地降低了水泥基材料的强度；硅烷-硅溶胶杂化材料可降低砂浆的吸水率，且随着杂化材料用量的增加，水泥砂浆的防水性能明显提高；三种杂化材料均具有较为明显的抵抗氯离子侵入混凝土的能力，且辛基三乙氧基硅烷-硅溶胶杂化材料抵抗氯离子侵蚀的能力最好。

Abstract:Three kinds of silica sol monomers were used, silica sol and silane hybrid material were prepared with organic-inprganic hybrid reaction. The effects of types and hybrid ratio of hybrid material on the mechanical properties, water resistance and resistance to chloride ion penetration of cement-based materials were investigated. The results show that a stable silica soil and silane hybrid material can be made with organic-inorganic hybrid reaction. Moreover, the stability of the hybrid material increases with the increasing of more alkyl groups and carbon number. Silica sol decreases the strength of cement-based materials to some extent. The silica sol and silane hybrid materials decrease the water absorption of mortar, and water resistance can be enhanced markedly with the increase of hybrid material dosage. The three kinds of hybrid materials greatly improve the concrete′s ability to resist chloride ion penetration, especially octyltriethoxysilane-silica does.

Keywords:silica sol and silane hybrid material; hybrid ratio; cement based material; water resistance; resistance to chloride ion penetration
