Enamels containing recycled brick waste
Tmejová, Jana ; Ptáček, Petr (referee) ; Opravil, Tomáš (advisor)
The diploma thesis deals with the possibilities of using recycled brick as a component in the preparation of glazes. Recycled brick is a mixture of crushed bricks, it can also contain a brick tablecloth, its composition and color makes this material practically identical to a brick shard. Due to these properties, it can be assumed that recycled brick can be used to prepare technical glazes with a specific color. The aim of the diploma thesis is to verify the possibilities of using recycled brick for the preparation of technical glazes. For prepared glazes, then evaluate their properties and estimate for which type of product these alternative glazes could be used.
The properties of contemporary clay bricks
Polláková, Lenka ; Skotal, Zbyněk (referee) ; Sokolář, Radomír (advisor)
Theoretical part of this bachelor´s thesis describes historical overview of progress of brickwork, including their technology, materials for production and products. Another part are requirements for solid burnt bricks, their properties and database of current manufacturers in the Czech republic and Slovakia. The practical part assesse the possibilities of manufacturers and determines the properties of the tested bricks, especially the salinity including frost resistance and appearance.
Possibilities of application of phosphate bond in brick abrasion dust treatment
Tmejová, Jana ; Havlica, Jaromír (referee) ; Opravil, Tomáš (advisor)
This bachelor´s thesis deals with possibilities of application of phosphate bond in brick abrasion dust treatment. Brick abrasion dust is produced as a secondary product of brick production during brick grinding. Brick abrasion dust is a relatively fine powder of the same composition as a burnt brick fragment. Since the brick abrasion contains an insufficient amount of the aluminum component, which is crucial for the formation of phosphate bond, the work is primarily concerned with finding a suitable aluminum dopant. The aim of the thesis is to find a suitable admixture that has a sufficient content of aluminum to form a phosphate bond and to determine the ideal amount to be added. Alternative sources of the aluminum component are tested in combination with a commercially available phosphate bond (Alufos 50).
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.
