Contemporary technology of clay bricks production - possibilities and perspectives
Polláková, Lenka ; Pavelka, Oldřich (referee) ; Sokolář, Radomír (advisor)
In the theoretical part, this diploma thesis deals with brick production, basic raw materials for brick production and the technological process of production itself. It also focuses directly on the fired brick, its legislative requirements and manufacturers who currently produce this brick in the Czech Republic and Slovakia. The possibilities of current manufacturers are assessed in the practical part, especially in terms of salinity, mineralogical composition and behavior during firing of their production mixtures. As last the optimal firing temperature of the available mixtures is designed to achieve ideal parameters as frost resistence, strenght, appearance etc.

Recycling of clay bricks dust as granulate
Prokopová, Zdeňka ; Pavelka, Oldřich (referee) ; Sokolář, Radomír (advisor)
The bachelor thesis is focused on recycling of brick sanding dust in the form of granulate produced on a pelletizing plate. The theoretical part describes the grog used in brick technology and possible methods of testing them. There are also examples of published experiments of how to produce or use artificial grog in the brick technology. There are also several examples of artificial grog that is currently available on the market. In the theoretical part, the behavior of the produced granulate from brick sanding dust on a pelletizing plate in a plastic dough was verified in laboratory conditions, then especially its behavior after passing through a laboratory roller mill. The change in granulometry and shape of the grog was evaluated. The distribution, granulometry and shape of the grog and the thermal conductivity of the fired shard were evaluated. For comparison, the standard used grog was used, namely quartz sand and quarry stone. Based on the results, it can be said that brick sanding dust granulate can at least partially replace another type of grog, but more extensive research is needed.
