On the project
Projekt bude zaměřen zejména na: 1. Studium dispergace nanočástic (zejména uhlíkových nanotrubic - CNTs) orientované na stanovení vlivu způsobu a parametrů dispergace a identifikace kvality disperze a definování účinné metody dispergace ve vodním prostředí. 2. Příprava cementových kompozitů s nanočásticemi (zejména CNTs) a studium vlivu koncentrace a typu nanočástic na strukturu, fyzikálně-mechanické vlastnosti a odolnost těchto cementových kompozitů vůči agresivním prostředím. 3. Studium odolnosti cementových kompozitů s nanočásticemi (zejména CNTs) vůči působení kontinuálních a pulsujících vodních paprsků.
Description in EnglishThe project will be focused mainly to: 1. Study of dispersion of nanoparticles (especially carbon nanotubes - CNTs) oriented at the determination of the influence of the method and parameters of the dispersion and identification of the quality of the dispersion and determination of the efficient dispersion method in aqueous environment. 2. Preparation of cement composites with nanoparticles (especially CNTs) and studying of the influence of the concentration and type of nanoparticles on structure, physical-mechanical properties, and resistance of the cement composites to aggressive environments 3. Study of the resistance of cement composites with nanoparticles (especially CNTs) to the action of continuous and pulsating water jets
