The synergistic resource utilization of solid waste represents a critical scientific challenge in the field of environmental engineering. This study innovatively proposes a solid waste-based fluid-filled material (FFM) to address the significant physicochemical differences among multi-source solid wastes, including drinking water treatment residues (DWTR), mixing station sediments (MSS), recycled fine aggregates (RFA), and mud. The results demonstrate that by precisely controlling the fluidity (160–200 mm), water-to-solid ratio (0.52–0.87), a...
