ResumeThe present work gives the current situation of the methods developed to measure the thermal conductivity of building materials used in Benin, country of western Africa. Modus operandi, basic theories and experimental results of the case of cement mortar were explicitly reminded. The thermal conductivity of the cement mortar is obtained on average at the value of 1.15Wm-1K-1. Then, the study focused on the influence of the simultaneous heat and mass transfer on these measures. Indeed, the methods of measurements participate, during their implementation, to a discrete but real drying of the material. To go further, a model of answer to one level perturbation was then proposed and has predicted the value of thermal conductivity of the cement mortar about 0,799Wm-1K-1.Therefore the double transport of heat and mass during the measurement of the thermal conductivity has an important influence about 30 %. The final analysis of this paper has justified relationships between properties and performance of materials.
