Abstract

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.
