Özet

In this study, thermal characteristics and kinetics of three different origin class-G cements (Mix, Bolu, and Nuh) were studied using thermogravimetry (TG/DTG) and differential scanning calorimeter (DSC). In DSC curves at different heating rates a number of peaks were observed consistently in different temperature intervals. TG/DTG is used to identify the detected phases and the corresponding mass loss. In the dehydration kinetic study of the different origin class-G cement samples, three different methods (Arrhenius, Kissinger, and Augis & Bennett) is used to determine the dehydration kinetic parameters of the cement samples and the results are discussed.
