MECHANICAL AND THERMAL CHARACTERIZATION OF CLAY WITH A VIEW TO POPULARIZING ITS USE AS AN ECOLOGICAL MATERIAL IN CONSTRUCTION

This work is carried out with the aim of enhancing the soils of Djarmaye in order to popularize its use as an ecological material in construction. However, a study of thermo-physical parameters was made to see the influence of cow dung in the mixture. As a result, thermal characterization tests were carried out, using the hot wire method for the determination of thermal conductivity, supported by the hot plane option for the determination of thermal conductivity.supported with the hot plane option for the determination of thermal effusivity was used. The test tubes are made with an incorporation of 0%, 2% and 4% by mass of cow dung. The parameters studied are the thermal conductivity, the thermal effusivity, and the thermal capacity by volume of the specimens. The results showed that the thermal conductivity decreases with cow dung, which confirms its use as an additive to obtain a good thermal insulator.
