Abstract: Compacted bentonite and a bentonite–sand mixture have been considered as a potential buffer material for nuclear waste stored underground. The effects of dry density, water content and sand fraction on the thermal conductivity of the mixtures were investigated via data collected with the transient line source technique. With those parameters known, a single expression for the thermal conductivity of the mixture is proposed.
