The development of composite material system with focus on matrix for extreme conditions
Gratclová, Kamila ; Gross,, Tomáš (referee) ; Bydžovský, Jiří (advisor)
The thesis deals with composite systems, with a focus on matrix resistant to extreme conditions. The aim of this work was to research and development matrix, resistant to high temperatures, typical in case of fire. Used theoretical knowledge were realized with subsequent laboratory research. Attention was paid matrices based binder mixed with any alkali activation of alternative raw materials and geopolymers. Scattered reinforcement featured polypropylene fibers. The subject of the practical part of the two alternatives, including a matrix based on basic ingredients - cement, alternative raw materials - high fly ash, blast furnace slag, geopolymer and polymeric components incl. combinations thereof. Laboratory research conducted by determining the fundamental material properties such as density, strengths, etc., after heat exposure. The developed materials were subjected to a temperature 1400 ° C. The conclusion was selected several recipes that were based on the resulting values found to be optimal.
Substitution of binder and filler of fire-resistant repair mortars using alternative raw materials
Gratclová, Kamila ; Dufka, Amos (referee) ; Bydžovský, Jiří (advisor)
The issue of protection and repair of reinforced concrete constructions affected by fire is very timely with respect to the dominant position of reinforced concrete as a building material. The aim is assessment of possibilities partial or complete substitution of the filler and the binder polymer composite materials intended for the repair of reinforced concrete constructions with higher resistance to fire.
