| 摘 要： | 高强水泥的生产近年来巳成为许多国家发展水泥生产的一个主要方向。在水泥中加入有机单体可以改善混凝土的质量,如加重量比为3％的有机硅烷偶联剂乙烯基三乙氧基硅烷CH_2=CHSi(OEt)_3(简称VTES)于水泥中,即可在较大程度上增加水泥石的强度。

| Abstract: | The hydrolysis of CH_2=CHSi(OEt)_3 has been studied. by ~1HNMR measurement. Thereaction was considered to be catalyzed by both H~ and OH~-; and the stronger the acidityor the basity, the more rapid the reaction. The reactant also influenced the hydrolysisreaction, especially in the initial period. Some information about the polymerization of thehydrolysis product of silane were obtained. |

| Keywords: | ~2HNMR vinyltriethoxysilane strengthening agent for cement hydrolysis polymerization |
