Lightweight mortars with content of alternative raw materials and resistant to adverse effects
Morkusová, Kristýna ; Jakubík, Aleš (referee) ; Bydžovský, Jiří (advisor)
This diploma thesis describes research and following development of lightweight cement mortars with alternative raw materials. Attention was focused on study of the effects of extreme influences such as high temperature (up to 1200 °C), freeze-thaw and agressive sulfur dioxide. Verification of durability of developed mortars was realized using physical and mechanical tests (density and strength), physical and chemical methods (computed tomography) and scanning electron microscopy. Assessment of durability was realized in a longer period of time (90 days).

Development of pelletization conditions for secondary energy products
Burešová, Eliška ; Batelka,, Michal (referee) ; Sokolář, Radomír (advisor)
This thesis deals with the use of secondary energy products. The teorethical part describes methods of separation of fine particles, characteristics and properties of secondary energy products and equipment suitable for pelletizing. On the basis of the theoretical part, the practical part designed and created suitable conditions for pelletizing two types of secondary energy products, namely brick dust and fly ash. These suggestions have been verified and both feedstocks and resulting pellets were tested. In accordance with the results, it is possible to say that the pelletized raw material has better properties than the raw material in its original powder state.

Possibilities of using light artificial aggregate based on sintered high-temperature fly ash in heat-resistant concrete structures
Mazán, Tomáš ; Sedlmajer, Martin (referee) ; Křížová, Klára (advisor)
The final thesis describes contemporary knowledge of research and development in the area of the heat-resistant concrete constructions with using porous aggregate from flying ash. The theoretical part introduces the production and the agloporit aggregate basic features. The principles of using in the incoming materials of light weight concrete are presented next. The thermal loading with influence at concrete constructions and the other individual materials is also mentioned in the final thesis. The experimental part of the thesis deals with the impact of lightweight aggregate quantity on the high temperature resistance. Conclusion pays attention to the obtained results evaluation and to the composition an optimal formula LWAC, which could be able to resist short-term thermal loading.
