The purpose of this work is to study the influence of the percentage of porosity, that is to say the volume of air compared to total volume on the thermal conductivity of clay at different degrees of temperature, this study is very interesting because clay is used in several fields for example construction, pottery, etc, and also in certain regions of the world as a building material and especially in countries which at a higher temperature, for this we perform together experiments on a mass of clay with a cubic shape of dimensions (10cm * 10cm * 10cm), but with each experiment we varied the percentage of porosity, then we relied on the CT-METRE device to measure the thermal conductivity
