Development of innovative composite systems ETICS on the basis of a new generation of secondary raw materials
Kováč, Michal ; Ševčík, Milan (referee) ; Drochytka, Rostislav (advisor)
This master’s thesis applies utilization of alternative raw materials in thermal insulation system of the ETICS of new generation for houses. The theoretical part dealt with the explanation of the ETICS and the selection of suitable raw material for his innovating. In the following practical part were used selected materials to create a new thermal insulation made of straw and binding materials of cement, casein glue, bicomponent fibers and mushroom mycelium. At the end have been applied the variants of base coat of clay and mineral screed on new thermal insulation, from which was selected the optimal variant. From optimal thermal insulation and suitable base coat was conducted proposal of final version of new ETICS.

Preparation and Properties of Roman Cement
Opravil, Tomáš ; Palou, Martin (referee) ; Škvára, František (referee) ; Havlica, Jaromír (advisor)
The Ph.D. thesis deals with the preparation of highly hydraulic binders based on roman cement. Roman cement (natural cement) is recently not available on the market due to uneconomic production of such a specific binder. On the other hand there is a big lack of information on this hydraulic binder. These results in failure in meeting the basic principle of modern approaches to restoration of historical buildings or monuments made of such kind of materials, which is such, that the materials used for restoration should be compatible with original material. Recognition of the processes of roman cement preparation based on progressive methods of study can provide substantial information for more efficient raw material selection or even for nontraditional utilization, for example for artworks. This work hence is aimed at studying and selection of traditional natural as well as nontraditional raw materials such as clay. This work also studies the preparation of highly hydraulic binders based on roman cement and the kinetics of burning and hydration processes

Analysis for the production of foam glass using alternative raw materials
Janák, Petr ; Brožovský, Jiří (referee) ; Bydžovský, Jiří (advisor)
Due to rapid technological development and continuously increasing amount of waste, people aim their emphasis at the enviromental protection and using of secondary raw materials. Glass has a high potential as a secondary raw material, because it is practically 100% recyclable. One way how to use the glass cullet is a production of foam glass. This Bachelor‘s thesis mainly deals with the possibilities of using recycled cullet and forecasting of alternative raw materials that can be used as foaming agents in the manufacture of foam glass.

Stabilization of the base layers of roads by using secondary raw materials
Buřičová, Karolína ; Kulísek, Karel (referee) ; Drochytka, Rostislav (advisor)
The bachelor's thesis deals with the up-to-date subject of secondary raw material usage. The aim of this thesis is to suggest a potential way of these materials’ usage by stabilization of base courses of road or railway constructions. Parameters of individual primary and secondary commodities are evaluated and the acquired knowledge in the field of stabilization is presented. An optimal technology for stabilization is suggested and applicability of used materials and their subsequently prepared mixtures is experimentally verified in the experimental work of this thesis.

Verification of the possibilities of using mixed cements CEM II and CEM III for concrete roads and bridges
Kepák, Ondřej ; Slánsky,, Bohuslav (referee) ; Hela, Rudolf (advisor)
Bachelor thesis focuses on verifying the possibilities of using blended cements CEM II and CEM III for concrete roads and bridges. The objective of the thesis was to verify the possibilities of the safe use of these cements. In the theoretical part, an overview of the types of cement produced in the Czech Republic is developed, including their characteristics and the state of use of blended cements in the world. In the experimental part are then presented the properties of the concrete produced from selected blended cements and compared with the reference cement without the addition of secondary raw materials.

Development of adhesive material for installation of cast basalt elements on metal base
Šikral, Martin ; Hodná, Jana (referee) ; Drochytka, Rostislav (advisor)
The diploma thesis deals with the development of polymeric adhesive material for the installation of cast basalt elements on a metal surface. The aim of this work is a development of the new adhesive material for the fixing of cast basalt elements to a metal base in high chemical stress environment and at higher temperature conditions. Furthermore, the thesis explores the possibility of using secondary raw materials as a substituttion of primary materials in the form of fillers. The thesis is also focuses on the determination of the advanced testing methods to verify the properties of devoloped adhesive materials, including monitoring the microstructure of the contact zone between the adhesive material and the surface.

Development of grounding enhancing cement composite mixture
Sochor, David ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
The diploma thesis deals with the development of a conductive cement composite grounding mixture for protection of building structures in areas with low conductivity. The theoretical part is focused mainly on the methods of buildings protections against lightning and overvoltage. The aim of this is to create a conductive composite with the possible use of secondary raw materials, which have a low electrical impedance value. The conclusion of the thesis is devoted to the evaluation of the efficiency of newly designed conductive composites and their possibility of incorporation into building protection systems against lightning or overvoltage.
