Synthesis, properties and product of hydration of strontium aluminate cement
Kocián, Karel ; Bartoníčková, Eva (referee) ; Ptáček, Petr (advisor)
This diploma thesis deals with non-traditional binder, which is strontium aluminate, with his preparation and hydration. The behaviour of binary and ternary mixtures of strontium-calcium-barium aluminates was also studied. These aluminates were prepared by firing an equimolar mixture of aluminum oxide and the appropriate carbonate. Samples prepared this way, including their mixtures, were characterized by analytical methods such as X-ray diffraction analysis (XRD), thermal analysis with evolved gas analysis (TG-DTA and EGA), scanning electron microscopy (SEM), infrared spectroscopy (IR) and calorimetry, with the greatest importance for the study of the hydration process.

The study of degasing process during thermal treatment of advanced ceramic
Kocián, Karel ; Šoukal, František (referee) ; Ptáček, Petr (advisor)
This bachelor thesis deals with mechanism and kinetics of the burnout of additives during thermal treatment of ferrite ceramics. In order to establish this process thermal analysis were used, specifically: simultaneous thermogravimetric determination, differential thermal analysis and thermal analysis with evolved gas analysis (TG-DTA and EGA), high-temperature microscopy (HM), burning test in kiln with controlled atmosphere and high-temperature X-ray diffraction (HT-XRD). To determine the elemental composition after sintering and characterization of the sample, scanning electron microscopy (SEM) was used.

Methodological tools for reducing road accidents on the expressway R46
Kocián, Karel ; Krpešová, Kateřina ; Frydrýn, Michal
The objective of contribution focuses on selected methodological approaches for reduction of road accidents. The lecture is focused on the following safety tools: Shortened analysis of traffic accidents, EuroRAP, drive-through safety inspection and conflict situations observation. In order to objectively compare these methodologies will then present the results of application of these safety tools on selected road section, which is R46. The final, the advantages of used methodologies based on empiric observations experienced within their application onto the sample road section, supplemented with recommendations on how to select the most suitable methodology in order to achieve a significant reduction of accidents on an arbitrary road section.
