The objective of this work is to determine the variation of thermal properties (thermal conductivity, volumetric heat capacity, thermal diffusivity and thermal effusivity) of red earth blocks, according to the compaction rates at different degrees of temperatures (20°C, 30°C, 40°C and 50°C). Several red earth samples were compacted with different centrifugal weights (250g, 500g and 1000g). Using the CT-meter, we measure the thermal properties of these samples experimentally in the dry state at different temperatures. The experimental results obtained show a significant increase in these thermal properties with the increase in compaction rate. However, as temperature increases, the thermal properties decrease for the samples studied.
