Development of lightweight composites based on foam glass aggregate
Szotkowská, Michaela ; Sedlmajer, Martin (referee) ; Zach, Jiří (advisor)
Bachelor´s thesis is concerned of development of bonding foam glass with organic binders. The theoretical part describes the use of recycled glass to produce aggregates based on foam glass. It also describes its production, properties and use in construction. The work also focuses on the types of organic binders and their properties. In the practical part, the optimal ratio between the binder and the filler is proposed and the subsequent assessment of the required properties of the final composite.

Change in costs and ecology of production of self-hardening molding mixtures in the production of spheroidal graphite iron
Šindlerová, Eliška ; Vondráček, Radek (referee) ; Záděra, Antonín (advisor)
This master thesis is focused on the study of the properties of core mixtures. The core mixtures are prepared from organic binders and processed by cold-box / amine technology. The mixtures are prepared of 3 different organic binder systems from 2 manufacturers. The evaluation is performed in terms of their flexural strength at specified time intervals and the results are compared with the specified strength criteria. Furthermore, the effect of water coating on the flexural strength of those core mixtures that met all the strength criteria in the first experiment is investigated. In the last experimental part of the work, the mixtures are evaluated in terms of their environmental friendliness. DSC / TG analysis is used to investigate whether any substances are released when the core mixture samples are heated. Subsequently, the mixtures were subjected to GC-MS analysis in order to identify the substances released.
