Usability of hig speed water jet in civil engineering
 Boucníková, Veronika ; Sitek,, Libor (referee) ; Bodnárová, Lenka (advisor)
The bachelor thesis deals with possibilities of using high-speed water jet in construction industry. In the theoretical part, water jet technology was generally described and a research for use in the construction industry with an emphasis on the application of concrete structures redevelopment and the process of interaction of water jet with concrete was done. Furthermore, the safety risks during work with high-speed water jet and the possibilities of recycling of waste generated by the use of this technology were evaluated. In the experimental part were prepared concrete samples with dispersed concrete reinforcement. The characteristics of the concrete samples were determined and the depth and appearance of the cross-section after interaction with the high-speed water jet was evaluated.

Study the concrete abrasion process by water
 Boucníková, Veronika ; Hela, Rudolf (referee) ; Bodnárová, Lenka (advisor)
The master thesis is focused on resistance of concrete against to effects of flowing water. In the theoretical part of the thesis mechanical and chemical effects of flowing water were described. The research of aspects that affects resistance of concrete against flowing water was done. Futhermore, the methods that evaluated resistance of concrete against flowing water were described. In the experimental part of the thesis the effect of concrete composition on resistance against mechanical and water abrasion was observed. Abrasive and plain high-speed water jet was used to simulate the effects of water abrasion. After interaction of concrete and water jet the relief and volume loss of material were observed.
