Study of Properties of Ettringite in Long Term Horizon
Křižanová, Lucie ; Kolář,, Karel (referee) ; Fridrichová, Marcela (advisor)
This thesis is focused on monitoring attributes of ettringite in long term horizon, especially on his thermodynamic stability. Ettringit was prepared in two ways. Firstly, it is a method of hydration of yeelimite, secondly, ettringit is prepared by addition of aluminium sulphate and calcium hydroxide.
Thermodynamic Stability of Thaumasite
Pospíšilová, Klára ; Dvořák, Karel (referee) ; Fridrichová, Marcela (advisor)
This work deals with the resolution of the identification characteristics of the thaumasit, which falls into the same group of AFt phases as the mineral ettringit. Both of these stages have the same structural arrangement and the morphology. This work’s specific goal is the synthetic preparation of thaumasit in a variety of conditions and its evaluation.
Effect of Selected Variables on the Properties and Stability of Ettringite
Kramoliš, Lukáš ; Kulísek, Karel (referee) ; Fridrichová, Marcela (advisor)
The thesis deals with the termodynamic stability of synthetically formed ettringite. It focuses on ettringite prepared by the direct synthesis of aluminum sulphate and calcium hydroxide. Stamples were stored in a laboratory environment and in a saturated water vapor. Monitoring of mineralogical composition was performed using XRD analysis, differential thermal analysis (DTA) and scanning electron microscopy (SEM).
Study of Properties of Thaumasite in Long Term Horizon
Pospíšilová, Klára ; Kolář,, Karel (referee) ; Fridrichová, Marcela (advisor)
This thesis deals with monitoring the thermodynamic stability of thaumasite and monitoring it is properties in the long term. The aim was to synthesize thaumasite under different conditions and to evaluate it using X-ray diffraction analysis and thermal analysis.
Study of the properties of thaumasite which was produced synthetically
Kábrtová, Denisa ; Jiroušková, Kateřina (referee) ; Fridrichová, Marcela (advisor)
The thesis is focused on the optimization of the thaumasite preparation in the way of ternesite hydration and further comparison of this approach to the other methods. The thaumasite was prepared by three different methods for this purpose - according to Aguilera et al., Purnell and the hydration method of ternesite clinkers. Finally, the X-ray diffraction analysis was particularly used to evaluate the obtained properties and results.
