注浆水泥性能模拟试验研究

Research on simulation test of grouting cement performances

论文通过室内模拟不同温度、不同水灰比情况下的试验,得到水泥的强度随温度的增高而降低,随水灰比的增加而降低的规律。该成果在高地温煤矿井下注浆应用中得到验证,从而可对高温注浆施工进行有效的理论指导。

From the tests under the different temperatures and different water and cement ratio simulated in the lab, the paper obtained the laws that the strength of the cement would be increased and decreased with the temperatures and the cement strength would be increased and decreased with the water and cement ratio. The results were approved in the cement grouting operation in a earth high temperature mine. Therefore the results will have an effective theoretic guidance to the high temperature grouting operation.
