Development of modern concrete for agricultural constructions
Švec, Vojtěch ; Slezák, Viktor (referee) ; Hela, Rudolf (advisor)
In agricultural buildings we generally encounter an environment that is full of aggressive substances and especially low pH. This work deals with this issue of concrete damage by acid environment and proposes their protection.
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.
