The issue of waterproof concrete for the concrete tunnel lining
Dipold, Václav ; Brožovský, Jiří (referee) ; Hubáček, Adam (advisor)
This bachelor thesis deals with a summary of requirements for waterproof lining of tunnels. Then focuses on the characteristics and requirements for concrete lining. Emphasis will be on requirements for fresh concrete, such as the hydration heat, the temperature requirements of concrete during storage and the requirements for concrete in the hardened state such as strength properties, modulus of elasticity and volume changes. Subsequently is discussed possibility of using SCC for this type of construction.

Study of durability of FRP reinforcements
Dipold, Václav ; Prokeš,, Jan (referee) ; Bodnárová, Lenka (advisor)
This thesis deals with monitoring the durability of FRP reinforcement in different types of environments which cause degradation. The theoretical part of the thesis describes reinforcing fibers, matrix materials, manufacturing technology of composite reinforcements by pultrusion and durability of FRP materials in environmental degradation. In the experimental part of this thesis was carried storing samples reinforcements in alkaline environment with various temperatures. As suitable were selected temperatures of 20 °C, 40 °C and 60 °C. Subsequently are described changes in physical properties of the reinforcements and tracking optical microscope.
