摘要
基于水泥土的早期(48h)固化试验,通过测试不同固化时间下水泥土的交流阻抗参数(|Z|,Z′,Z″,θ),揭示了各参数随时间的变化规律。在对各参数变化机理解释的基础上,对水泥土固化过程划分了溶解期、诱导期和硬化期3个阶段。研究表明,水泥土的|Z|、Z′、Z″和θ随时间的变化可以较好地解释水泥土固化过程中离子的溶解、水泥的水化、水泥水化产物与土中活性物质的硬凝反应等复杂过程。
On the basis of the solidification experiment of cemented soil at early solidfying stage（within 48hours）,its AC impedance parameters（｜Z｜,Z′,Z″,θ） were measured,and the relationships between the parameters and age time were discovered.The results show that the solidifying stage was divided into dissolving period,induction period and hardening period according to the variation trend of AC impedance parameters.The parameters explained the ions dissolving,cement hydration and sclerosingreaction at the early solidifying stage.
