Brick Dust Arising During Grinding of Burnt Brickwork and Possibilities of its Utilization
Kocmánek, Tomáš ; Sokolář, Radomír (referee) ; Nevřivová, Lenka (advisor)
The diploma thesis focuses on the brick dust arising during grinding of burnt brickwork and the possibilities of its utilization. In the theoretical part origin and basic properties of brick dust is described. Some published results of research on the potential utilization of brick dust in various industries are presented here. Also proposal of utilization of brick dust in the ceramic industry is presented. In the practical part two ceramic raw materials and the two brick dust with different granulometry arising during grinding of burnt brickwork (made from these two ceramic raw materials) were selected. The effect of the addition of brick dust to the ceramic raw materials on the physical - mechanical properties of ceramic body after sintering was investigated.

Development of pelletization conditions for secondary energy products
Burešová, Eliška ; Batelka,, Michal (referee) ; Sokolář, Radomír (advisor)
This thesis deals with the use of secondary energy products. The teorethical part describes methods of separation of fine particles, characteristics and properties of secondary energy products and equipment suitable for pelletizing. On the basis of the theoretical part, the practical part designed and created suitable conditions for pelletizing two types of secondary energy products, namely brick dust and fly ash. These suggestions have been verified and both feedstocks and resulting pellets were tested. In accordance with the results, it is possible to say that the pelletized raw material has better properties than the raw material in its original powder state.

Boards with alkali activated binder filled with wood chips
Gajdušková, Patricie ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
For the production of cement chipboards, cement is used as a binder which is an ecological burden for our planet. This diploma thesis deals with research into the possibility of replacing it with other alternative materials, especially those that are created as a by-product of other production. The focus is primarily on slag, heating plant slag or brick dust. The theoretical part deals with the previous studies and theoretical knowledge of alkaline-activated matrices which are supplemented with an organic binder such as wood chips which are used to reinforce the boards. The practical part deals with the above-mentioned alternative materials which are tested for the design of recipes for modified boards made of alkali-activated binder reinforced with chips. These modified recipes are subsequently subjected to physical-mechanical tests such as bending strength, modulus of elasticity and other monitored parameters of the boards. Selected board variants were analysed in terms of mineralogical composition and microstructure.

Possibilities of using recycled brick in binders systems with p-clinker content
Tušla, Václav ; Ptáček, Petr (referee) ; Opravil, Tomáš (advisor)
This diploma thesis deals with the preparation binder systems based on Portland clinker and recycled brick. Recycled brick is considered a waste material from construction or production of brick products. This thesis uses finely grounded brick recycled and brick dust, which is produced during final processing of burnt bricks. By incorporating brick dust in alternative system based on Portland clinker could bring ecological and economic benefits. This diploma thesis deals with option using brick dust as pozzolan admixture to Portland clinker, with the aim to prepare and test Portland cement, which is defined in v ČSN EN 197-1. This thesis also deals with possibility preparation of alternative binders based on p-clinker, but those not defined by ČSN EN 197-1. Specifically these are ternary binders with fluid bed ash and binders based on hybrid cements containing sodium sulfate.
