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.

Study of the effect of sealing paints on the resistance of concrete to weathering
Sláma, Radek ; Hela,, Vlastimil (referee) ; Hubáček, Adam (advisor)
Purpose of this bachelor thesis is to summarize existing knowledge of sealing paints and evaluate its effect on concrete surface. Emphasis is placed especially on description of single paint type, application methods and description of degradation effect on concrete, which protective painting should prevent. In experimental part of this thesis are researched properities of chosen sealing paintings types on resistence of concrete to wheathering. Observed tests are especially absorption, resistance of concrete surface to effect of chemical and defrosting substances and depth of penetration of water under pressure.
