Thermal properties of rocks after cyclic heating

Original language description

It is possible to determine the thermal characteristics of rock samples and find the best rock material for heat storage using laboratory measurements. We determined values of thermal conductivity degradation after cycles of heating. The specific heat capacity did not degrade. Stabilization of changes of thermal conductivity varied between the studied materials from 2 to 6 heating cycles. In general, it can be said that for all the studied rocks the largest decrease in thermal conductivity was observedafter the first to the second heating cycle. Based on the measured values of the thermal constants of the studied rocks, granite (PD) with the highest values of specific thermal conductivity and specific heat capacity was selected as the most suitable rock material for energy storage.
