To address the challenges of limited space, quality control issues, and ensuring stable self-compaction backfill materials in trench backfilling projects, a loess-based cement slurry was developed as flowable material by using loess primary base incorporating an appropriate amount admixture for solidification improvement. The permeability, collapsibility, disintegration were analyzed varying content curing age. slump test first conducted to determine optimal water contents, aiming 180 mm. Subsequently, compressive strength tested orthogonal experimental design. analysis revealed mix ratio slurry: 8% naphthalene sulfonate formaldehyde condensate, 3% sodium sulfate, 0.5% thiosulfate, 0.08% ethylene glycol. Experimental results indicated that with 4% content, exhibited maximum permeability coefficient 0.977 × 10 −5 collapsibility 0.865 −2 , confirming both meet required standards. When exceeds 6%, paste shows minimal collapse. This study offers efficient reliable technical solution operations regions.

ABSTRACT A theoretical model of the migration process high‐alkalinity red mud particles in porous media was derived from granular thermodynamics, complying with complementary motion two‐phase flows (i.e., hydroxide ions and powder). From perspective energy dissipation provoked by particle molecular thermal motion, a suspended under mixed conditions established. This naturally considers complex adsorption/desorption between (or particles) medium solid matrix, as well particles. Moreover, reveals dynamic deposition effect powder multiphase interactions during temporal spatial variations. The progression substances transient injection filtrate different pH values continuous change were verified experiments.
