Hydration Kinetics Model on Binary System of Fly Ash-Cement Paste

Compared with ordinary Portland cement,there is cement hydration reaction and fly ash volcano reaction in fly ash-cement paste. Considering the dilution effects,physical and chemical effects of fly ash on cement hydration dynamics,a micro hydration model on binary system of fly ash-cement was established based on the center particle hydration model,and it can be used to predict the relationship between fly ash-cement hydration rates varies with the hydration degree.
