| 摘 要： | 将外掺剂应用于水泥土改性研究,在水泥加固土的基础上添加硅粉、天然浮石粉、钠盐、表面活性剂等材料,有效地改善了水泥土的力学性质,明显增强了水泥土的耐久性。试验表明,一定掺量下的硅粉、天然浮石粉、钠盐、表面活性剂等外掺剂能够显著提高水泥土的抗压强度及耐久性。通过室内试验探讨了外掺剂水泥土的强度特性,分析了外掺剂对水泥土的改性效果,旨在为硅粉等外掺剂应用于工程实践开展理论和试验研究探索。

| Abstract: | The additive was applied to change the property of cement soil.When the cement soil was made,the additive materials such as the powdered silicon,natural powdered pumice,sodium salt and surface active agent were added into the cement clay.It was found that,through the experiment,these additives can effectively improve the mechanical property and increase the compressive strength and frost resistance property.The strength characteristic and effect of cement clay with added admixtures were studied by experimen... |
