Study of new types of admixtures for waterproof concrete
Sikorová, Věra ; Másilko, Jiří (referee) ; Kalina, Lukáš (advisor)
This bachelor thesis is focused on the influence of crystallizing admixture for waterproof concrete. Reference concrete samples and modified concrete samples were prepared with different dosing of the crystallizing admixture, on which the standard test – the depth of penetration of water under pressure was carried out. The rheological properties of fresh concrete were verified by a slump test. The mechanical properties of the hardened concrete were examined by a compressive strength test. The mechanism of effect of the crystallizing admixture has been studied by scanning electron microscopy and X-ray diffraction analysis.

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.
