Issues of design and testing of waterproof concrete fot tunnel lining
Merta, Michael ; Voves, Jiří (referee) ; Hubáček, Adam (advisor)
The diploma thesis deals with the issue of waterproof concrete and testing its properties. The theoretical part is conceived through research on existing knowledge relating to waterproof concrete. Emphasis is placed on the possibility of using a waterproof concrete for structures, such is e.g. tunnel lining. The experimental part is focused on the laboratory testing of waterproof concrete. Particulary examined was the effect of various admixtures as a partial replacement of cement. Monitored was the development of compressive strength and flexural strength, development of temperature during hydration in the early stages of maturation of concrete, water resistance of concrete, concrete surface resistance to water and chemical de-icing agents, as well as development of shrinkage during concrete maturation.

The possibility of using admixtures for waterroof concrete
Roháček, Lukáš ; Voves, Jiří (referee) ; Hubáček, Adam (advisor)
Bachelor thesis is mainly focused on additions, that have impact on water impermeability and other properities of fresh and hardened concrete. This issue is also described in short section, which is took from foreign reaserch. Thesis further discusses about the standards and regulations that determine, what properties should have waterproof constructions. Experimental part is showing influence of fly ash, slag and silica fume on conzistency, hydratation heat development, strenght, water impermeability, frost resistance and volume changes of the concrete.
