Ultrasonic measurement of large format tiles
Čaněk, Michal ; Topolář, Libor (referee) ; Kocáb, Dalibor (advisor)
The diploma thesis deals with influence of the used adhesive to large format tiles properties after installation. Properties on large format tiles were monitored by ultrasonic pulse velocity method. Hydraulic setting adhesives were tested in second part. Strength and modulus of elasticity were tested. The development of shrinkage over time was also monitored. The results were summarized in tabular and graphical form and were examined by simple statistical analysis to determine resulting conclusions.

Study of mutual influences of volume changes and internal stresses of flow floor screeds
Mikeš, Vít ; Štenko,, Miroslav (referee) ; Šťastník, Stanislav (advisor)
This thesis deals with the comparison of volumetric and stress variations in different formulations of cast floor self-leveling screeds during maturation. These changes were measured by several methods. Furthermore, the strength parameters of the test materials were compared. The test specimens were cured in metallic and elastic forms. The microstructure of these samples were monitored by scanning electron microscopy. In conclusion, the suitability of the tested methods for the given type of flooring materials was evaluated.

Results of Anorthite Creation in ceramic Body
Beránková, Karla ; Šveda,, Mikuláš (referee) ; Sokolář, Radomír (advisor)
Anorthite is crystalline phase in the ceramic body. Is acquired on burning a mixture of calcium ceramic raw material. This work deals with the influence on the resulting properties of anorthite ceramic body, especially flexural strength, porosity, shrinkage, thermal expansion coefficient. And the influence of different CaO sources on the properties. As a source of CaO was used calcium carbonate, calcium hydroxide and fluid fly ash.
