The Issue of testing shotcrete
 Škapová, Pavla ; Hela,, Vlastimil (referee) ; Hubáček, Adam (advisor)
The master‘s thesis focuses on testing the shotcrete prepared in laboratory conditions. The main observed properties are compresive strenght of shotcrete and modulus of elasticity. The aim is assessment of methods for measuring those parameters. The calibrating correlations for strenght characteristics of shotcrete are given by obtaining the results of used methods. The shotcrete composition, amount and type of accelerating additive as well as economic aspect of using shotcrete is also assessed.

Verification of the possibilities of using mixed cements CEM II and CEM III for concrete roads and bridges
 Kepák, Ondřej ; Slánsky,, Bohuslav (referee) ; Hela, Rudolf (advisor)
Bachelor thesis focuses on verifying the possibilities of using blended cements CEM II and CEM III for concrete roads and bridges. The objective of the thesis was to verify the possibilities of the safe use of these cements. In the theoretical part, an overview of the types of cement produced in the Czech Republic is developed, including their characteristics and the state of use of blended cements in the world. In the experimental part are then presented the properties of the concrete produced from selected blended cements and compared with the reference cement without the addition of secondary raw materials.
