Lightweight concrete with reinforcement
Plochý, Ondřej ; Hubertová,, Michala (referee) ; Hela, Rudolf (advisor)
This bachelor thesis summarizes the current knowledge regarding to the design and properties of lightweight concrete and concrete with reinforcement. Also deals with research of lightweight aggregate concrete with Liapor and its interaction with dispersed steel fibers. The work examined recipes of volume classes D1,6 and D1,8 and strength classes SFRLC 20/22 and SFRLC 25/28. Recipes are monitored by physical-mechanical and rheological properties.

Lightweight composites based on fluid filter ashes
Palovčík, Jakub ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
This Bachelor’s thesis deals with preparation, study and analysis of binders based on fluid filter ashes. Binders were doped with various additives to alter the rheological properties, reduce volumetric weight and increase flexural compressive and tensile strength. Next, a possibility of using waste polyester fibres for reinforcement in matrices based on above mentioned binders was determined. The prepared samples were tested for compression and flexural strength after 28 days. Phase composition was analysed by means of X-ray diffraction analysis.
