Physico-mechanical properties of the system syenite-enclave in the Královec quarry
Umlauf, Jiří ; Sluková, Michaela (referee) ; Krmíček, Lukáš (advisor)
The bachelor thesis focuses on mechanical properties of syenitoids and their mafic microgranular enclaves collected in actively mined quarry Královec near Jaroměřice nad Rokytnou. In overview part of the thesis are described selected methods for determining the physical-mechanical properties of the rocks as well as geology of the studied site. The practical part brings the results and principal conclusions from the measurements of the mechanical properties of these rocks.

The effect of temperature on the mechanical properties of greywacke
Brabec, Marek ; Horák, Vladislav (referee) ; Krmíček, Lukáš (advisor)
The author of this master's thesis studied the influence of high temperatures on Lower Carboniferous greywacke sampled in the Kobeřice quarry near Prostějov. Two sets of cylindrical bodies were produced, made of fine and relatively coarse-grained greywacke. The samples were then fired at temperatures up to 1200 °C. Thermally altered samples were then studied in laboratory using rock mechanics and petrography methods. Results of the study were then carefully interpreted to determine relations between the rock parameters, structural changes and the firing temperature. The master's thesis also contains a brief insight into rock thermomechanics, necessary theoretical background to the used methods and geological context of the Drahany Upland, where the samples of the tested greywacke were taken.
