摘要
将某工地的三种土体(淤泥、粉质粘土和砂土)分别与一定量的水泥砂浆混合制备水泥土试样,测试不同龄期和不同掺量水泥土的电阻率,并分析其相关关系.研究发现,水泥土电阻率随龄期、水泥掺量和强度的增大而增大,并且,所制备的水泥土电阻率按淤泥、粉质粘土和粉砂的顺序依次增大.用本文建立的水泥土电阻率计算公式,可以计算不同龄期和不同掺量时水泥土电阻率值,进一步换算可得水泥土无侧限抗压强度值.
A certain amount of cement was added to mud, silty clay and sand at one site, respectively, to make the cement - soil samples, and the electrical resistivity of cement - soil with different age and cement content were measured, their relationship was analyzed. It is found that the electrical resistivity of cement - soil increases with the increase of age, cement content and strength, those of made by mud, silty clay and silt are in order of increasing. The established formula can be used to calculate the electrical resistivity of cement - soil with different cement content and age, and fatherly to calculate the value of unconfined compressive strength of cement - soil.
