Physicochemical and Mechanical Characterization of Ceramic Materials from Meknes Region (Morocco)

This scientific paper presents a comprehensive study of the physical and chemical properties of a clay sample collected from Meknes region of Morocco. X-ray diffraction analysis revealed the presence of kaolinite, muscovite, and quartz minerals in the clay sample. X-ray fluorescence analysis showed that the sample contained a significant amount of aluminum and silica. The Atterberg limit test indicated that the clay has a high plasticity index and is classified as a clay of low to medium plasticity. The ATG_DSC analysis revealed that the sample underwent multiple endothermic reactions, including dehydration, dehydroxylation, and decarbonation, at different temperature ranges. Shrinkage and weight loss experiments showed that the clay exhibited high shrinkage and weight loss upon drying. SEM-EDX analysis provided information on the microstructure and elemental composition of the clay sample. The water absorption test revealed that the clay has a low water absorption capacity. The three-point flexural test showed that the clay bricks had high flexural strength, which makes it suitable for use in high-stress applications. Overall, the results suggest that the clay sample can be used in a variety of applications, including building materials, ceramics, and other industrial uses.
