The objective of this study is to predict the properties of the layers, including their thermal conductivity, thermal diffusivity, porosity and P and S wave velocities. The results of the study of the impact of the organic matter content of the samples on the petrophysical measurements show that, regardless of the organic matter content, thermal conductivity and diffusivity remain insensitive, while P and S wave velocities decrease linearly and porosity increases with increasing organic matter content. On the other hand, the study of the organic matter variability content is consistent with the velocity ratio, so can be used as an organic matter indicator of the layers. Conductivity and thermal diffusivity are almost invariant to the variability of the organic matter.

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. Nomenclature D is the thermal diffusivity (m 2 /s) E is the thermal effusivity (J/m 2 .K.s 1/2)  is the thermal conductivity (W/m.K) C is volumetric heat capacity (kJ/m 3 .K)

This material is characterized by partially replacing the cement with recycled soda lime glass. The cement was partially substituted (10, 20, 30, 40, 50 and 60% in weight) by glass powder with a water/cement ratio of 0.4. The glass powder and four of the seven samples were analyzed using a scanning electron microscope (SEM). The thermophysical properties, such as thermal conductivity and volumetric specific heat, were experimentally measured in both dry and wet (water saturated) states. These properties were determined as a function of the glass powder percentage by using a CT-Meter at different temperatures (20 °C, 30 °C, 40 °C and 50 °C) in a temperature-controlled box. The results show that the thermophysical parameters decreased linearly when 60% glass powder was added to cement mortar: 37% for thermal conductivity, 18% for volumetric specific heat and 22% for thermal diffusivity. ...

Wood is defined industrially as an anisotropic and heterogeneous material formed over many years of a tree's life. The anatomical study of wood generally involves the examination of three directions of reference, the axial, radial and tangential directions. And a study of the constituent elements of wood being oriented in several directions, it follows from experience that its thermal properties differ in the longitudinal, radial or tangential direction, where thermophysical tests are carried out at wood moisture contents between 10 and 11%. Concerning the thermal properties, study highlighted, the determination of thermal conductivity, specific heat, thermal diffusivity and then the thermal effusivity of araucaria wood at different temperatures: 25°C, 35°C, 50°C and 60°C. The results are obtained experimentally by a device called ''CT-Metre''. He illustrated that this kind of wood is more conductive of heat in the longitudinal direction than the radial and tangential directions. Also, have determined the evaporation rate under well determined conditions, chose an enclosure to keep the set temperature, and then add NaCl to keep humidity at 75%, which also gives important results.
