Abstract :In this study, fine fractions of bentonites from the Çankırı and Kütahya regions were treated with Na2CO3 and H2SO4. The resulting materials were analysed by X-ray diffraction insert ignore into journalissuearticles values(XRD);, thermogravimetric and differential thermal analyses insert ignore into journalissuearticles values(TGA, DTA); and infrared insert ignore into journalissuearticles values(IR); spectroscopy. Surface areas of the samples were also measured. The results showed that structural changes were observed by treatment with Na2CO3 and H2SO4. These changes showed differences depending on exchangeable cations, clay type and the ratio of additives.Keywords : Bentonite, soda activation, acid activation
