An empirical model for the thermal conductivity of compacted bentonite and a bentonite-sand mixture

摘要

The thermal conductivities of compacted bentonite and a bentonite-sand mixture were measured to investigate the effects of dry density, water content and sand fraction on the thermal conductivity. A single expression has been proposed to describe the thermal conductivity of the compacted bentonite and the bentonite-sand mixture once their primary parameters such as dry density, water content and sand fraction are known.
