11	Studium vlastností ettringitu v dlouhodobém horizontu / Study of Properties of Ettringite in Long Term Horizon Křižanová, Lucie January 2018 (has links) 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.
12	Sledování termodynamické stability thaumasitu v závislosti na zvolených vnitřních a vnějších parametrech / Monitoring the thermodynamic stability of thaumasite depending on selected internal and external parameters Ďurtová, Aneta January 2019 (has links) This thesis deals with thermodynamic stability of thaumasite in dependence on selected external parameters. It focuses on optimizing preparation by ternesite hydration and comparing it with other methods in a suitable environment. Specifically, using the saccharate method, followed by the hydration of ternesite clinkers and the influence of calcium aluminate phases on the stability of thaumasite produced by the hydration of ternesite clinker. Subsequently, the phase composition was evaluated by X-ray diffraction analysis, in some cases by electron microscopy.
13	Sledování vývoje AFt fází ve směsných portlandských cementech s fluidním popílkem / Monitoring the Development of AFt Phases in Mixed Portland Cement with FBC Ash Martykán, Jiří January 2016 (has links) This diploma thesis is focused on evaluation of the possibilities of using FBC ash for production of blended cement and monitoring the hydration process, specially creation of the AFt phases.

15	Ověření možnosti syntetické přípravy ettringitu a thaumasitu / Verification of the synthetic preparation of ettringite and thaumasite Hrdina, Matěj January 2015 (has links) The work is focused on the possibilities of using FBC fly ash for composite cements, monitoring their hydration processes, especially the creation of AFt phase. The possibility of preparing synthetic ettringite and thaumasite and their detection.
16	Ověření termodynamické stability ettringitu / Verification of the Thermodynamic Stability of Ettringite Pekárková, Jana January 2016 (has links) 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.
