Comparison of microstructure of standard and modified fly ash autoclaved aerated concrete
Fleischhacker, Ján ; Kulísek, Karel (referee) ; Drochytka, Rostislav (advisor)
Nowadays, the amount of produced fly ash and fluidized ash is huge, so it is important to find ways of its proper use.Significant influence in field of fly ash consumption is production of autoclaved aerated concrete. Most important factor in production is properties of raw materials such as mineralogical and chemical composition. The study of raw materials is important to understand the mechanism of hydratation, tobermorite formation and mineralogy of final product. In present study, we investigate influence of raw materials to mineralogy of autoclaved aerated concrete, significantly to influence of fluidized ash on quality of autoclaved aerated concrete. Closure of study is design of the methodology, specialized in field of bachelor’s thesis study.

Artificial stone - methods of preparation and properties
Pluskalová, Barbora ; Bayer, Patrik (referee) ; Rovnaník, Pavel (advisor)
The aim of the thesis „Artificial stone – Methods of preparation and it´s properties“ deals with the various methods and issues concerning the preparation of artificial stone. The thesis presents the summary of materials and various methods suitable for the preparation and points out mechanical properties, including durability of material, which serves as an alternative to natural stone. Further on, the thesis deals with the studies of binding systems based on geopolymers, which are used for the artificial stone preparation. This part of the thesis is associated with the experimental part, which is aimed at choosing the suitable mixing ratio of binder to aggregate in the artificial stone based on metakaolin geopolymer. According to the results of mechanical tests and aesthetic impression the author chose the best composition and then created a decorative element.

Czech-Spanish and Spanish-Czech printed dictionaries
BRABCOVÁ, Eva
The theme of this Bachelor thesis is the description of the Czech-Spanish and Spanish-Czech printed dictionaries. The work is divided into two parts - theoretical and practical. In the theoretical part we dealt with the form and the content of bilingual dictionaries, with its macrostructure and microstructure. In the second part which is practical we analyzed selected Czech-Spanish and Spanish-Czech dictionaries and we compared its elements of structure. After the analysis of each dictionary we mentioned the evaluation of the dictionary. At the end of the work we summarized the evaluations. We mainly used the dictionaries containing commonly used vocabulary. Smaller part of the analyzed dictionaries is focused on economic vocabulary.
