Possibilities of utilization of brick-grind-dust in systems based on portland cement
Palovčík, Jakub ; Kalina, Lukáš (referee) ; Opravil, Tomáš (advisor)
This thesis deals with possibilities of using brick-grind-dust which is a secondary product from manufacturing of grinded bricks. A boom in this method of masonry is connected with an increase of production of these secondary materials. These secondary materials are partly returned to brick manufacturing and partly buried in a landfill site. Due to their composition and origin, these materials are potentially pozzolan active, making them interesting for applications in hydraulic binders. The aim of the work was to study the physical and chemical properties of several brick-grind-dust and brick sands. Subsequently, binders based on these materials and Portland cement were prepared. The properties of the binders were modified by means of adding a commercially available polycarboxylate superplasticizer. The development of mechanical properties of the prepared binders has been studied over time. Hydration of the selected binders was analyzed by isothermal calorimetry.
Ecological liquidation of photovoltaic cells and modules
Demchikhin, Sergey ; Veselý, Aleš (referee) ; Vaněk, Jiří (advisor)
The first part of this master’s thesis contain the history of photovoltaic technology and types of PV cells. Gave a consideration to advantages and disadvantages of solar cells. Compared their effectiveness and important parameters. In the next part described the recycling technology of modules at the end of their lifetime. Described certain recycled materials. At the end of the work described possible improvements to existing technologies used for encapsulating of cell. And wich would improve the recycling process.
