Monitoring the thermodynamic stability of ettringite depending on selected internal and external parameters
 Kolaja, Filip ; Hoffmann,, Oldřich (referee) ; Fridrichová, Marcela (advisor)
This diploma thesis is focused on long term monitoring of thermodynamic stability of ettringite under selected conditions and its possible destabilization or transformation into another AFt phase, especially thaumasite. Ettringite samples were made in two ways, by hydrating the yeelimite in the system with the alite and by addition of aluminium sulphate and calcium hydroxide.

Influence of Ambient Temperature Conditions on Course of Solidification of Cement Stone
 Kolaja, Filip ; Kulísek, Karel (referee) ; Fridrichová, Marcela (advisor)
Bachelor thesis in theoretical part deals with raw material, chemical and mineralogical structure of portland cement. With technology of his production, basics clinker minerals and his hydration. There is indicated also partitioning of cements. In experimental part is observed influence of extremely low and high temperature to the course of hydration of cement stone in compare with reference sample, hydrated at normal temperature conditions.
