| 摘 要： | 对广东某斜拉桥拉索内的压浆进行综合测试分析，并作有关的模拟试验。研究结果表明，拉索内灌浆离析，使浆体中的水分、FDN高效减水剂等富集于拉索上段；在较大水灰比，一定浓度FDN高效减水剂及密闭条件下，水泥浆体会长时间不凝结。对浆体此异常特性作了理论探讨。

| Abstract: | The cement paste in the tie rod sleeves of a certain bridge in Guangdong was tested synthetically, and some model tests were done. Results show that: Cement paste in tie rod sleeves produced segregation, and some materials such as water, FDN high-range water reducer and etc.concentrated at the higher part of tie rod sleeves. Under the conditions of higher water-cement ratio, a certain consistency FDN high-range water reducer and hermetic surrounding, the cement paste did not set in a long time. The mechanism of paste abnormal character was discussed. |
