thermal properties of crushed rock

Thermal and physical properties of reconsolidated crushed
Abstract. Crushed salt can be used as backfill to bury and conduct heat away from radioactive waste in salt repositories. As the crushed salt compacts during reconsolidation, its thermal, mechanical and hydrologic properties will change in a manner related to the porosity.

Which Rocks Absorb Heat the Best? Hunker
The energy density of stone is the specific heat multiplied by its density on a unit basis. This gives a number that shows how well a rock can store heat, if every rock is the same size. The stone with the highest energy density will have the greatest ability to absorb heat, for a given thickness or size.
