Shield tunneling generates substantial waste muck, conventional landfill and drainage disposal depletes land resources, causing ecological harm. Solidification enhances resource efficiency. Employing metal ion complex ZY-1 fortifies the hydration process in shield tunneling muck solidification. Through potential testing, the influence of ZY-1 on ζ potential across various particle surfaces was analyzed. Findings indicate metal ion complex effectively reduces ζ potential on various particle surfaces, diminishing the outer electric layer thickness, narrowing particle spacing, and enhancing consolidation. ZY-1 shows the most significant reduction in ζ potential on cement particle surfaces; at a concentration increase from 0 to 100 mmol/L, cement particle ζ potential decreases by 61.61%. The sequence of metal ion complex impact on ζ potential across different particle surfaces is as follows: cement > shield muck > calcium carbonate > calcium sulfate > calcium hydroxide.
