Description
  • Cementová pasta je důležitá složka ostatních inženýrských heterogenních materiálů, jako je např. beton. Použitím mikromechanického přístupu lze vlastní elastické vlastnosti jednotlivých složek přenést až na úroveň desítek mikrometrů. Model hydratace cementu byl vytvořen pro předpověď mikrostruktur hydratující pasty a v kombinaci s mikromechanikou poskytuje mocný nástroj pro předpověď elastických vlastností. Diskuse je věnována oběma modelům stejně jako výpočetním nárokům homogenizace. Ověření na cementových pastách s vodním součinitelem 0,2 - 0,5 je v dobré shodě s experimenty. (cs)
  • Cement paste is the important component of other engineering heterogeneous materials, such as various kinds of concrete. Using the micromechanic approach, intrinsic elastic properties of individual components of cement paste are upscaled to the scale of tens of micrometers. Cement hydration model has been developed for a prediction of microstructures of hydrating cement paste and in combination with micromechanics provides sufficient tool for prediction of elastic properties. Both models are discussed as well as the computational requirements of homogenization. Validation on the pastes with water-to-cement ratii 0.2 - 0.5 shows good correlation with experiments.
