Synthetic Preparation and Properties of Thaumasite
Klásková, Silvie ; Dvořák, Karel (referee) ; Fridrichová, Marcela (advisor)
This thesis continues in the monitoring of thaumasite thermodynamic stability. It mainly deals with mineral properties and possible ways of its synthetic preparation. Mineralogical composition determined using X-ray diffraction analysis as well as possible impact of sample storage conditions can help further property identification. Based on the obtained radiographs, thaumasite mineral can be well distinguished from the very similar ettringite mineral.

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.
