In this paper, the results of experimental study concerning the calorimetric measurements of heat of hydration of cement pastes with different w/c ratio and different hygral conditions are presented. The model of cement hydration proposed by Parrot and Killoh [1] is implemented in the model of concrete at early ages by Gawin et al. [2], which allows us to carry out simulations of the evolution of...
W pracy przedstawiono model matematyczny izotermicznego wyługowywania wapnia z kompozytów cementowych, w pełni nasyconych wodą, który uwzględnia kinetykę tego procesu. Jest ona opisana za pomocą termodynamiki reakcji chemicznych, przy użyciu tzw. charakterystycmego czasu procesu. Omówiono też metodę numerycznego rozwiązania równań tego modelu za pomocą MES. Przeanalizowano wpływ kinetyki wyługowywania...
