水泥稳定土延迟时间对强度和干密度的影响

The Influence of the Delay Time of Cement Stabilized Soil on Strength and Maximun Dry Density

通过对商丘一开封高速公路No.15标、No.16标水泥稳定土的击实试验和无侧限抗压强度试验,分析讨论了水泥稳定土延迟时间对强度、干密度的影响.认为在施工中应根据不同土质的延迟时间来指导和控制施工过程,以保证抗压强度和压实度,满足设计要求。

The Influence of the delay time of cement stabilized soil on the strength and maximum dry density was analysed by the compaction test and unconfined compressive strength test of NO. 15 and N0. 16 of the Shangqiu-Kaifeng expressway cement stabilized soil. We should instruct and control the process of the construction according to the delay time of different soil to make sure that the degree of compaction and the compression strength to conform to the design extect.
