水泥改良湿陷性黄土的配比研究

Cement improved collapsible loess ratio study

在黄土中按干质量百分比为5%,10%,12.5%,15%,20%的比例掺入水泥,然后对所配制的水泥土进行重型击实、无侧限抗压强度等试验,研究了不同水泥配比的最优含水量、最大干密度和无侧限抗压强度等指标随水泥掺入量的变化规律,从而确定出水泥和土合适的配比。

In loess percentage of dry mass by 5 %, 10%, 12.5 %, 15 %, 20% of the proportion of blended cement, and then for the preparation of cement-soil to carry out heavy tamping, unconfined compressive strength such experiments, the effects of different cement ratio of the optimum moisture content, maximum dry density and unconfined compressive strength with cement and other indicators of the amount of variation, in order to determine a cement and soil suitable ratio.
