Study of Phase Changes During Portland Clinker Firing
Pertlová, Alena ; Fridrichová, Marcela (referee) ; Gazdič, Dominik (advisor)
The presented bachelor thesis deals with monitoring of transformations during the burning of cement clinker. The theoretical part is devoted to the theories regarding the burning of Portland clinker and to the description of clinkers properties in general. The focus is put on the modern low-energy clinkers as well. Moreover, the thesis deals with several methods for determining the phase composition of cement clinker including HT-XRD analysis, which allows to monitor the behaviour of individual phases at high temperatures besides the determination of the phase composition. In the experimental part, there is introduced the project proposal of the model raw mixture used to produce ordinary Portland clinker and raw mixture of low-energy ternesite clinker. Furthermore, the thesis shows HT-XRD analysis done in the high temperature chamber, followed by the evaluation of results and their comparison with the theoretical background.

Study of limestone decarbonation process
Koporcová, Diana Mária ; Bureš,, Jaroslav (referee) ; Dvořák, Karel (advisor)
Submitted master´s thesis examines research of connections between the type of limestone and the process of decarbonation. Types of limestones and genesis of limestones are described in the theoretical part of the thesis, followed by the description of the process of decarbonation, methods used for analysis of limestone structure and research of solved problems. Experimental part of the thesis describes HT-XRD analysis, SEM analysis and simultaneous TG/DTA analysis performed on chosen group of limestone samples. The process of decarbonation and the change of microstructure of the developing calcium oxide are examined from the obtained data.
