Study possibilities of nanotechnology in cement composites
Kardošová, Romana ; Bodnárová, Lenka (referee) ; Hela, Rudolf (advisor)
The aim of this paper is to summarize and assess the possibility of using nanoparticles as additives in concrete. These particles have the ability to improve the mechanical and physical properties of cement composites or even gave them brand new ones. Industrial use is hampered by effective incorporation of nanoparticles into the matrix, the health and environmental risks and, last but not least, the financial costs. The experimental part of the thesis deals with the dispersing nanosilica and nanometakaolin particles in aqueous solution and their subsequent integration into the structure of cement mortar.

High-grade concrete using nanoparticles
Labaj, Martin ; Bodnárová, Lenka (referee) ; Hela, Rudolf (advisor)
The aim of this paper is to summarize and assess the possibility of using nanoparticles as additives in high performance concrete. These particles have the ability to improve the mechanical and physical properties of cement composites or even gave them brand new ones. Industrial use, however, is hampered by several obstacles. In particular, it is the task of effective incorporation of nanoparticles into the matrix, the health and environmental risks and, last but not least, the financial costs. The experimental part of the work deals with the first-mentioned problem, namely with dispersing carbon nanotubes in aqueous solution and their subsequent integration into the structure of cement mortar.

Impact of input parameters on the quality of mixing dispersion of nanoparticles
Cederová, Kristýna ; Hela, Rudolf (referee) ; Bodnárová, Lenka (advisor)
The bachelor thesis deals with nanoparticles. It examines the process of dispersion of nanoparticles in particular. Nanoparticles have the ability to improve some physical properties of cement composite materials. One, but important obstacle for correct application of nanoparticles is its dispersion. The experimental part of the thesis is dedicated to the dispersion of nanoparticles. Properties of cement composites were set in a time of 7 and 28 days. Nanoparticles were examined under transmission electron microscope.

Study of dispersion of carbon nanotubes in cement composites
Michnová, Kamila ; Hela, Rudolf (referee) ; Bodnárová, Lenka (advisor)
Carbon nanotubes have the ability to improve the mechanical and physical properties of cement composites. However, their introduction into industrial utilization is hampered by several obstacles. It primarily involves the effective incorporation into the cement matrix, health and ecological risks. The experimental part of the work deals with the dispersing carbon nanotubes in aqueous solution and their subsequent integration into the structure of the cement matrix.
