The objective of this work is to measure on an experimental scale the variation of thermo-physical properties of red earth blocks substituted by wood powder. Red earth is widely used as a building material and its thermo-physical properties are generally improved by adding different types of fibers. This study was conducted to analyze the effect of wood powder stabilizer on compressed red earth blocks. Several red earth samples were substituted with wood powder in different percentages of 0%, 5%, 15% and 20% by weight, respectively. Using the CT-meter, we measure the thermo-physical properties such as thermal conductivity, volumetric heat capacity, density and deduce the thermal diffusivity and thermal effusivity by empirical relations. The experimental results obtained show a significant decrease in thermal conductivity, so we can consider that our material can be used to improve the thermal comfort of the building.
