Composite materials based on alcali activated blast furnace slag with admixture of fly ash
Indra, Ivo ; Brandštetr, Jiří (referee) ; Opravil, Tomáš (advisor)
This thesis concerns on substitution of blast furnace slag or its part with fly ash in alkali-activated systems based on aluminosilikates. Classic, fluid bottom and fluid filter fly ashes will be tested. The goal is to prepare geopolymer with required mechanical properties, but with maximal admixture of alternative raw materials. In composites with substitutioned slag or its part the thesis focuses mainly on workabilityof fresh mixture, pressure and bending strenght. Use of secondary raw materials has advantages in the economic point of view and it´s friendly to enviroment, too.

Pipe screw conveyor for fly ash transport
Žaloudek, Vilém ; Zeizinger, Lukáš (referee) ; Škopán, Miroslav (advisor)
This bachelor's thesis deals with design and constructional solution of oblique tubular screw conveyor for transportation of power plant ash from silo to further technological processing. In this thesis evaluation of fundamental dimensions, design of power unit, design of bearings, evaluation of filling of the through and strength control of selected components of screw conveyor is done. This thesis consists of evaluation report and drawing documentation.

Continual helicoidal mixer
Pelka, Tomáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma project works out and is focused on the continual mixing process of the particular matters. The project is divided into following chapters. Chapter 1 includes mixing theory and information of the experimental work of the particular matters for blade using. In chapter 2 there is Evaluation and calculation of the technical parameters for the mixer. Chapter 3 deals with the engine proposal and chapter 4 includes calculation and design work of the gear transmission. Chapter 5 includes the stress analysis of the shaft and blade with the I-deas software. In attachment there are also the mixer arrangement drawing and detailed drawings of the key parts and groups for the mixer.
