Indirect methods to assess the solid particle thermal conductivity of Quebec marine clays

摘要: Thermal and frost action analyses in soils require the knowledge of thermal conductivity soil solid particles. This parameter was obtained using reverse modeling applied to data Quebec marine clays. Values ranged from 2.2 3.2 W/mK mostly due variation quartz fraction. The mean forming minerals other than equal 2.15 W/mK. A modified geometric model thus proposed estimate clay particles based on minerals. Several for literature were also analyzed confirm experimental results this study further clarify fraction influence Finally, basic geotechnical helped establish empirical relationships estimation a as function either clay-si...
