Verification of properties of concretes with nanoparticles
Diplomová práce se zabĂ˝vá posouzenĂm vlivu pĹ™Ădavku uhlĂkovĂ˝ch nanočástic do cementovĂ˝ch kompozitĹŻ. Teoretická část diplomovĂ© práce je zaměřena na rešerši informacĂ o uhlĂkovĂ˝ch nanočásticĂch, pĹ™esnÄ›ji o uhlĂkovĂ˝ch nanotrubiÄŤkách a grafen oxidu. Jsou zde shrnuty metody dispergace uhlĂkovĂ˝ch nanotrubiÄŤek a jejich vliv na cementovĂ© kompozity. Praktická část navazuje na rešerše z části teoretickĂ©. V prvnĂ fázi byla ověřena správná technika dispergace grafen oxidu. NáslednÄ› byly ověřeny účinky grafen oxidu na mechanickĂ© vlastnosti cementovĂ˝ch malt. V závÄ›reÄŤnĂ© fázi diplomovĂ© práce byly poznatky zĂskanĂ© z pĹ™edchozà části ověřeny na betonovĂ˝ch vzorcĂch.This diploma thesis deals with the influence of addition of carbon nanoparticles on cement composites. The theoretical part of the diploma thesis is focused on the research of information about carbon nanoparticles, more precisely about carbon nanotubes and graphene oxide. There are summarized methods of dispersing carbon nanotubes and their effects on cement composites. The practical part follows the theoretical part of the research. In the first phase, the correct technique of graphene oxide dispersion was verified. Subsequently, the effects of graphene oxide on the mechanical properties of cement mortars were verified. In the final phase of the diploma thesis, the knowledge gained from the previous part was verified on concrete samples.
