Verification of the composition of the concrete durability of cement-concrete covers
Černá, Eva ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
Alcali – silica reaction often causes destruction of a concrete.constructions. In the theoretical part is described creation and causes of the ASR including assessment of individual components of concrete and their testing. The practical part is devoted to the results of some control tests of the concrete cover in the section 18 of the highway D1 (Měřín - Velké Meziříčí) and section D1-20 (Velké Meziříčí - Lhotka), the mechanical properties of the upper and the lower layer of the concrete cover and measuring the resistance of concrete against chemical deicing agents.

Possibilities of increasing durability of concrete in highly chemical aggressive environment in agriculture
Sláma, Radek ; Slezák, Viktor (referee) ; Hubáček, Adam (advisor)
In recent years there has been a significant increase in the production of concretes for agricultural buildings, especially in the area of exposure to higly chemically aggressive environments. The aim of the thesis is to describe and summarize the existing knowledge about the durability of concrete exposed to the effects of highly chemically agressive environment. Furthermore, emphasis is placed on the description of individual additives and admixtures increasing the resistance of concrete to the effect of harmful substances. In the experimental part, the effects of individual types of additives, admixtures and sealing coatings on increasing the resistance of concrete against the effect of highly chemically aggresive environment are investigated in the laboratory.
