摘要：This study aims to characterize four geological layers (T, Y, X, M) of MoroccanTimahdit’s Oil shale and of Jerada coal waste to evaluate their suitability as alternativematerials for cement manufacturing. Mineralogical and chemical characterizations ofthese materials in a raw state, and at different heat treatment’s temperature, were carriedout by various methods: X-ray fluorescence, X-ray diffraction, infrared spectroscopy andthermogravimetric analysis (DSC/TGA). The DSC/TGA analysis confirmed the presenceof organic matter in oil shale with a combustion heats between 3459 J/g (layer M) and5368 J/g (layer Y), while coal waste has less heat power with 889.2 J/g. Chemical andmineralogical composition of the studied materials and their thermal behavior indicatethat these materials would be energetically beneficial in the production process ofPortland clinker if they are used as alternative fuel. In addition, residues after oil shalelayers burning can be used as pozzolan or hydraulic materials in cement, since they haveshown a good activity.
