Characterization of brick clays for the production of THERM bricks
Svobodová, Markéta ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
The Bachelor´s thesis is focused on the comparison of brick claysthat arecalcium and non-calcium and then it determines which of these brick clays are suitable for production of thin wall thermal insulating fittings called THERM. The main influence has CaO contained in the calcium brick clay in the form of calcite. In the theoretical part you can find an overview of the brick clays in the Czech Republic and abroad then requirements for clays and laboratory testing of bricks. In the practical part of the work were performed tests on samples of brick clays used in the Czech Republic. Mineralogical composition differenceis obviousafter firing the brick clays.This difference is caused by occurrence of anorthite calcium brick clay which then reflects in the usefulproperty of brick shard. Based on these tests I make evaluationof the most suitable type of brick clay for processing the THERM fittings.

Possibilities of brick clays ageing ability acceleration
Nečasová, Zdislava ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
This master thesis is focused on comparing the options available to accelerate thematuring period of brick dough. There were four types of brick clay from differentfactories of the Czech Republic. From each of these four earth were created by three tests. One dough was stored in the laboratory, the second was heated in an oven and the third dough was added sulphite liquor. In these tests was studied mainly maturing and then further the effect the swallowed sulphite liquor on other properties (plasticity, sensitivity to drying, drying change of length and flexural strength). The result of job evaluation should be, how much time and how it will reduce the time of maturing.
