ABSTRACT
Thermal conductivity—indispensable for assessing loess heat transfer and stability—was analyzed in saturated/unsaturated states under varying moisture, density, and temperature using a Netzsch HFM 446. Results show unsaturated remolded loess exhibits moisture-dependent conductivity increases, with water content being the dominant factor. A predictive model integrating moisture, dry density, and mineral composition demonstrated high accuracy, validated through experimental data and published literature.
Keywords: Remolded loess, Thermal conductivity, Dry density, Water content, Predictive model.
