The major object of this work is the development of heterogeneous materials of red earth. We know that the red earth, since ancient times, has been an advantage in several areas such as energy efficiency in buildings and industry as well as in health. It is present in a large quantity and at a lower cost (the source of the red earth of Oulja, Sale, Morocco) in powder form doped with copper also in powder form. Indeed, this study is based on a global approach of the properties of the material, accompanied by an in-depth analysis of the characteristics, chemical, mineralogical, structural and morphological, by means of X-ray diffraction (XRD), scanning electron microscope (SEM), and chemical microanalysis by energy dispersive X-ray spectroscopy (EDS). This experimental study showed a homogenization of the two materials due to the morphological modifications revealed by the SEM, the appearance in XRD of the additional lines characterizing the interactions of the copper particles with those of the red earth as well as the appearance of the peaks characterizing the mass and atomic percentages of copper in the red earth.
