Monitoring of alkalis in Portland clinker
Siudová, Alena ; Šoukal, František (referee) ; Opravil, Tomáš (advisor)
This bachelor thesis focuses on the localization of alkali in Portland clinker and their properties, which can significantly affect the lifetime of the concrete produced from these cements. The bachelor thesis deals with the study of the phases of the alkali in Portland clinker and the compounds they represent. Further, the bachelor thesis deals with the study of the rate of transfer of alkali into solution when mixing Portland clinker with water. Several different Portland slinks are analyzed and compared. The aim of the thesis is to try to find a connection between measured experimental values, clinker composition and alkaline-silica reaction precursors.

Advanced PC/ABS blends
Siudová, Alena ; Lepcio, Petr (referee) ; Ondreáš, František (advisor)
This diploma thesis studies mixtures of polycarbonate and acrylonitryl-butadiene-styrene. It deals with optimization of their production on laboratory scale and characterization of their properties. It compares the results with a sample prepared by a commercial partner in normal production. It tries to improve the properties of the prepared mixtures by means of nanofillers, compatibilizers and toughness modifiers. It compares and discusses the results of individual recipes, namely the relationships between microstructure, rheological properties and mechanical properties.
