Possibilities of utilization of boiler slag
Fialová, Gabriela ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
This bachelor thesis studies the boiler slag (slag) and its potential use in refractory materials industry. It concentrates its on chemical and mineral composition. Mullite parts and Fe2O3 probably lowers the melting point and heat resistance. During the work is proposed and experimentally validated a method for reducing the content of iron in the slag shares.Is observed the effect of the reduced number of iron units for the heat resistance of the material. The results are further processed and assessment. Thermal resistance was monitored using incandescent microscopy.

The possibilities of utilization of scoira from high-temperature combustion of coal
Dobeš, Jiří ; Švec, Jiří (referee) ; Opravil, Tomáš (advisor)
This thesis deals with the possibility of usage boiler slag in construction industry and related fields. Within this study is observed the influence of the amount of added boiler slag on the properties of pastes and mortars based on Portland cement. The influence of the addition of superplasticizer was further studied as well. The prepared samples were tested for mechanical properties such as tensile strength, bending and compression strength in the time dependence of the standard wet storage. The obtained data were further processed and evaluated.

Self-leveling floors based on secondary raw materials
Darakevová, Michaela ; Šiler, Pavel (referee) ; Opravil, Tomáš (advisor)
The work deals with the use of secondary raw materials in the self-leveling floor systems when used as a secondary raw material perform here especially classic ash, boiler slag and gypsum from flue gas. Work is looking for ways in as much as possible to replace conventional materials used in self-leveling flooring systems, secondary energy products. The aim of this work is to determine the optimal amount and ratio of secondary raw materials in self-leveling flooring compounds so that they are maintained or improved standard properties of these compounds reported in the standards. The work is divided into several points, the first point was first sought appropriate composite binder, where it was used as aggregates reach a standard sand. At other points the sand was then replaced by secondary materials. Were also tested ingredients to influence the rate of cooling, or for the onset of the initial strength.
