Design of grout joint for chemical exposure using secondary raw materials
Matušková, Veronika ; Hodná, Jana (referee) ; Drochytka, Rostislav (advisor)
The aim of the bachelor’s thesis is the design of a high-quality polymeric grout joint using secondary raw materials and hazardous waste for increased chemical exposure. The main use assumed of the proposed grout joint is grouting of the cast basalt elements in building objects that are systematically exposure due to the highly aggressive chemical load. The use of input materials produced by progressive technologies should be another benefit of this grout joint to enhance the ecological aspects of the grout joint production.

Immobilization of heavy metals in the cement matrix with the admixture of natural zeolite
Semerádová, Nikol ; Bayer, Patrik (referee) ; Vyšvařil, Martin (advisor)
Heavy metals released to the natural ecosystem constitute significant risks not only for organisms, but also for water supplies in the nature. There are a number of analytical methods for the determination of heavy metals. Each of them is suitable for different element and its character. Since the results of the analysis are applied during the solidification and stabilization, it is necessary to ensure the highest correlation between hazardous waste and solidification medium for maximum inhibition of toxic ions. This work investigates the stabilization of heavy metals binders based on cement base with admixture of the natural zeolite and its possible use for the solidification of heavy metals in soluble form.
