研究了湿磨细水泥灌浆过程中制浆时间对浆材 性能的影响，结果表明：高速搅拌时间Tg、湿磨时间Ts、低速搅拌时间Td均对浆材性能有不同程度的影响。提出了灌浆施工过程中湿磨细水泥的最优控制时间， 并进行了微观测试和分析。

The effects of mixing time in grouting process of we tground cement on motrar properties were studied.The results showed that high speed mixing time(Tg),wetgrinding time(Ts) and lowspeed mixin gime(Td) all have effects on properties of cement paste with different d egree.At last,the optimum controlling times of wetground cement were given and the microstructure test of hardened cement mortar was analysed.
