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。
The unconfined compressive strength test and the voltammetry resistivity test were used to test the compressive strength and resistivity of cemented soil under the double action of domestic sewage erosion and freeze-thaw cycles. The unconfined compressive strength The results show that the compressive strength of cement-soil with different numbers of freeze-thaw cycles varies with the concentration of domestic sewage, and the erosion concentration is 40% of the compressive strength of cement soil is the largest, so the concentration of Hohhot, 40% of the domestic sewage can be used as the relevant engineering cement soil mixing water. In addition, the relationship between unconfined compressive strength and resistivity was established.
