Application of metakaolin in refractory materials
Tvrdík, Lukáš ; Rovnaníková, Pavla (referee) ; Havlica,, Jaromír (referee) ; Kutzendőrfer,, Jaroslav (referee) ; Lang, Karel (advisor)
Refractory materials are irreplaceable in all industrial fields where it is necessary to use high temperatures. This paper deals with the use of metakaolin in refractory materials that allows the operation of such facilities. In recent decades has the development made significant progress in quality parametres, which extended life period of refractory materials in their use and significantly decreased the specific consumption of refractory materials in various technologies. This phenomenon is also called "harakiri effect". At the same time a constant pressure to the lowest prices of products is on the refractory market. Metakaolin seems to be appropriate raw material, which may help to achieve interesting qualitative effects. It may affect many properties of the influence on the behavior of materials during processing, through physico-mechanical parameters and dipping to the economic efficiency of production.
Interaction between asphalt binder and filler
Indráková, Kristýna ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The thesis is mainly focused on comparison of properties of mastics, that were mixed in lab. The samples of mastics were mixed of paving bitumen in combination with 9 samples of backhouse filler, 1 inappropriate sample containing mica and 1 sample of additive filler. The folowing tests were used for assessment of samples: The particle density of filler-pyknometer method, The delta ring and ball test, The complex shear modulus and phase angle, The multiple stress creep and recovery test. The tests results were evaluated and compared. The results of the thesis are listed in the conclusion.
