摘要
采用无侧限抗压强度测试试验以及伏安法电阻率测试试验对经受生活污水侵蚀及冻融循环双重作用下的水泥土进行抗压强度及电阻率测试,观察水泥土的无侧限抗压强度及电阻率随着不同的侵蚀浓度,不同的冻融循环次数的变化情况,试验结果表明,不同冻融次数的水泥土抗压强度随生活污水浓度的变化而不断的变化,受侵蚀浓度为40%的水泥土抗压强度强度是最大的,因此呼和浩特地区浓度为40%的生活污水可以作为相关工程水泥土搅拌用水。此外,建立了无侧限抗压强度与电阻率之间的关系。
In this experiment, taking the unconfined compressive strength test experiments and vohammetry resistivity experiments to test the unconfined compressie strength and electrical resistivity of cement - soil under withstand sewage erosion and freeze - thaw cycles, At the same time, observe the variation of the unconfined compressive strength and resistivity of cement - soil with different concentrations and freeze- thaw cycles in different curing period,The tests show that different number of freezing and thawing of ce- ment - soil compressive strength and constantly changing along with the change of concentration of sewage, the erosion concentration of 40% strength of cement - soil compressive strength is the biggest of all, so the Hohhot area concentration of 40% of sewage soil - ce- ment mixing water can be used as a related project, while establish the relationship between the unconfined compressive strength and electrical resistivity.
