The Use of Tensograf for Optimization of the Composition of Mortars
Hrbáček, Matěj ; Melichar, Tomáš (referee) ; Žižková, Nikol (advisor)
Bachelor thesis is focused on monitoring of volume changes in concrete composites. Using Czech and foreign literature searches are processed, in which mortars in general are described. Thesis is further concerned with description of polymer-modified mortars and with explanation of polymer-matrix forming mechanisms. The following are noticed volume changes and experimental methods of their investigation. The last part describes in detail the Tensograf TGF-02. Experiment is performed by monitoring the volume changes in polymermodified mortars using Tensograf TGF-02 and it is verified its suitability for the subject matter.

Heat resistance of wood bondlines
Šustáček, Jan ; Melichar, Tomáš (referee) ; Vaněrek, Jan (advisor)
This thesis is focused on studying the impact of elevated temperatures on the resistance of bonded joints. The aim of this study is to assess the impact of exposure to temperatures on selected types of adhesives. In the theoretical part was made research and comparison of selected species agglomerated materials and described the issue of fire safety of buildings. To determine the strength characteristics of bonded joints at different temperatures have been made in the practical part load tests according to valid standards.

Desin of new technologies for invert grouting of masonry sewer
Dolák, Martin ; Melichar, Tomáš (referee) ; Drochytka, Rostislav (advisor)
The subject of this work is to find optimal grouting mixture for repairing existing brick sewer with insistence on ecological modesty. Secondary raw and waste materials will be evaluated as a partial replacement of good-quality materials, that are commonly used. Production wastes for which is after necessary adjustment found usage in another sphere of production are named secondary raw materials. In the end will be made a selection of appropriate secondary raw materials for a project of new technology of back grouting identified for repairing currently used brick sewers.
