Possibilities of utilization of brick-grind-dust in alternative binding systems based on fluidized ash
Tušla, Václav ; Švec, Jiří (referee) ; Opravil, Tomáš (advisor)
This bachelor´s thesis deals with usage of brick-grind-dust in alternative binding systems based on ashes of fluid combustion. Specifically it deals with fly ashes and softly milled bed ashes of brown coal combustion. Primarily thanks of content of free lime, anhydrite and other components, fluid ashes have binding properities. Brick-grind-dust arise in end formation of burned bricks. The aim of thesis is to verify, possibilities to create composite of appropriate abilities with high or even exclusive amount of fluid ashes and brick-grind-waste. The paper also deals with influence of some chemical modifying additive on this alternative systems.

Possibilities of affecting the portland cement hydration by the addition of fluidized ash
Nehybka, Josef ; Bartoníčková, Eva (referee) ; Opravil, Tomáš (advisor)
This work is focused on study of possibilities of influence of hydration of Portland cement with an admixture of fluid ashes. The work deals with the tests with fluid filter ashes and milled fluid bed combustion ashes. Predominantly, a calorimetric measurement is used for study of admixtures. The prepared samples were found out on their mechanical parameters as the tensile bending strength and compressive stress. X-ray powder diffraction was used to determine of phase composition of the raw materials and created samples after hydration.
