Hydro-physical properties and durability study of cement slurry material based on loess

Year: 2025

Type: article

Abstract: Collapsible loess in Northwestern China challenges infrastructure backfilling. This study creates a new loess - based cement composite slurry (LCCS) with 8% cement and additives. LCCS has a high 180 - mm slump, a low permeability of 2.1 × 10⁻⁶ cm/s at 8% cement, and its collapsibility coefficient is less than 0.009. Durability tests show it has 27% better frost resistance than plain cement slurry, though with more sulfate - induced mass loss. LCCS uses 30% less cement than conventional CLSM, cutting costs and carbon emissions. Thus, it's a promising green alternative for backfilling in such areas.
