Study of usabiliti of sands for preparation of aeroconcrete in hydrotermal condition
Straka, Radek ; Ptáček, Petr (referee) ; Opravil, Tomáš (advisor)
A building industry is expanding branch all the time and it intervenes in the life of everyone. Aeroconcrete is very attractive and actual subject nowadays because economy is important point of view of production. This material finds a wide-spread use thanks to its specific properties. The good manipulation and great thermal insulating properties are secured by its porous structure. Furthermore, proper material selection provides a saving of power of house for every customer demands. Due to aeroconcrete's sufficient compressive strength it is useful for both constructions and internal walls. Fundamental and very important for final material properties is raw material composition of aeroconcrete. A relationship between composition of filler (quartz sand) and resultant properties of aeroconcrete is an objective of the thesis.

Effect of the Composition of Alkali Activator on the Properties of Geopolymer Materials
Rinnová, Martina ; Bayer,, Patrik (referee) ; Rovnaník, Pavel (advisor)
The master thesis discusses the alkali-activation of aluminosilicate material (metakaolin), specifies the main components of geopolymer mixture, evaluates the influence of geopolymer mixture composition and the influence of other factors on final properties of geopolymer. Results of the mechanical properties and microstructure of the geopolymer pastes made out of metakaolin activated by various amounts (50–110 % by weight of metakaolin) of liquid water glass (with varying modulus from 0,5 to 3,0) or NaOH as well as KOH solution are presented in the experimental part.
