Effective Thermal Conductivity (ETC) of particulate beds is an important property to many processes in industries such as pharmaceutical, food, nuclear and casting and solidification technologies. This paper presents an experimental research that examines the dependence of the ETC of soil due to changes in the average temperature of the particulate beds, and the stresses on the particles (as derived from the pressure on the top face of the beds).A uni-axial cylindrical experimental system was composed. The ETC was measured by the experimental system while either the pressure on the particulate beds or the average temperature of the beds was changed.
