Behaviour of Ettringite in Different Humidity Conditions at Increased Temperature
 Hučínová, Lenka ; Kulísek, Karel (referee) ; Fridrichová, Marcela (advisor)
This thesis focuses on the behaviour of ettringite as a highly watery material under varying external environment conditions. It deals with the development of ettringite at increased temperature and in different humidity conditions. Depending on these factors, both the stability of ettringite and its possible conversion to different minerals are monitored.

Verification of the Thermodynamic Stability of Ettringite
 Pekárková, Jana ; Jiroušková, Kateřina (referee) ; Fridrichová, Marcela (advisor)
The thesis deals with possibilities of FBC fly ash utilization for composite cements. It focuses on thermodynamic stability of ettringite, which is produced during composite cements hydration. Specific tasks are dedicated to observation of influence of outdoor environment and influence of calciumhydrosilicate environment to stability of ettringite.

Properties Modification of Portland Cements Oriented to Reduce CO2 Emissions
 Rybová, Alexandra ; Jiroušková, Kateřina (referee) ; Fridrichová, Marcela (advisor)
The thesis is oriented on monitoring of hydration process of portland cement based on fluidized bed ash, firstly on investigation of AFt phases, mainly ettringite and thaumasite. Specific aim of the task is to prepare the scheme of these minerals synthetic preparation and to verify their laboratory preparation by different ways, using methods of RTG-diffraction analysis and scanning electron microscopy.
