针对钻孔灌注桩及地下连续墙施工过程中产生的工程废弃泥浆工程特性差、产量大、污染易扩散、堆场占地成本高、处置效率低及处置成本高等问题，以絮凝-固化法为基础，结合建筑垃圾-矿渣基固化剂，研究其对于高含水率泥浆和低含水率泥浆的固化效果，并对低含水率泥浆固化体电化学阻抗响应进行系统分析和评价。结果表明，当矿渣粉∶建筑垃圾粉∶生石灰=6∶3∶1时，固化体无侧限抗压强度最大。电化学阻抗谱（electrochemical impedance spectroscopy,EIS）测试结果验证了以上结论。综上，从固化效果与效率以及电化学阻抗响应等方面验证了基于固废的絮凝-固化联合处置工程废弃泥浆的可行性与优越性，同时该种固化剂较水泥具有更好的经济效益，其应用前景广阔。
Abstract：Aiming at the problems of waste slurry generated during the construction of bored piles and diaphragm walls including poor engineering properties, high yield, easy pollution diffusion, high storage site occupation costs, low treatment efficiency, and high disposal costs, the solidification effects of flocculation-solidification method combined with construction waste-slag-based stabilizers on both high-water-content and low-watercontent slurries were investigated herein. A systematic analysis and evaluation of the electrochemical impedance response of the solidified low-water-content slurry were conducted. The results show that when the ratio of slag powder ∶ construction waste powder ∶ quicklime is 6∶3∶1, the maximum unconfined compressive strength of the solidified body is reached. This conclusion was further validated by electrochemical impedance spectroscopy(EIS) test results. In summary, the feasibility and superiority of the flocculation-solidification combined treatment of waste slurry based on solid waste were verified in terms of solidification efficiency, electrochemical impedance response, etc. Moreover, compared with cement, this stabilizer exhibits good economic benefits and broad application prospects.
