Three sites of Benin’s clays from Gbédji-Kotovi, Massi-Sèhouè and Zogbodomey were characterized in this study. Physicochemical
and mineralogical analysis were performed by X-Rays Diffraction, chemical analysis, thermal analyses ATD/ATG,
infrared IR, specific surface area and granulometry. Density of clayey particles, capacity of cationic exchange (C.C.E.) and
exchangeable bases were also done. It comes out from these analyses that clays of Zogbodomey are essentially kaolinitic
while those of Gbédji-kotovi and of Massi-Sèhouè are with smectitic predominance. By its composition the sample of
Zogbodomey is constituted by a natural mixture of the elements necessary for the production of ceramic (bricks, tiles, pottery
etc). The two others series of samples from Gbédji-kotovi and Massi-Sèhouè will require some kaolinite and sand additions
because of their strong proportion in smectite. Thus, they would be more useful in agronomy and environmental protection |
