Non-energy uses of lignite
Zedníčková, Petra ; Taraba, Boleslav (referee) ; Pekař, Miloslav (advisor)
This bachelor thesis is focused on the meaning of coal and it's utilize. It is especially concentrated on lignit and it's utilize out of energetic sector. Lignit constitudes geologicly youngest type of coal and belongs to caustobiolits , which is solid with various degree of coalification of original phytomasa. Degree of coalification is situated between peat and lignit. Lignit is characteristic by clearly well-kept structure of wood. Exactly this relative youth of lignit is reason for it's interesting qualitative indexes, in which belongs especially it's natural sorptive ability and quite high volume of humic acids. Both of these characteristics cohere together, because humic substances will certainly be main reason for sorptive characteristics. Coal, in comparing with other natural material, is by it's structure very complicated mixture of both organic and inorganic substances in various states of matter. It is matter of heterogenous system of macromolecules, which is structured of microscopicly distinguishable and chemically various substances. It can be composed of organic components or work as mineral admixture.

Development of structural concrete with power plant ash
Ťažký, Martin ; Sokol, Pavel (referee) ; Hela, Rudolf (advisor)
Worldwide production of concrete is increasing, what has a negative environmental load of cement production. That is due to effort in building construction, also concrete production, greater use of the secondary raw materials. Fly ash is the most commonly used secondary raw material. His used has a very good impact on the economy and ecology of production and positively affects on the properties of concrete in both the fresh and hardened state. The aim of this bachelor's thesis was to improve its use in concrete, using a minimum void fraction of dry mix cement-fly ash.
