This paper describes development of a kinetic cement hydration model, wich observes hydration rate relative to time. The model established makes it possible to observe hydration rate relative to time and not relative to the reaction degree, wich offers a new approach to solving the cement hydration kinetics. The model assumes several simultaneous processes esquentially governing individal hydration segments. The model has been tested by means of experimental data obtained from the DSC plots by quantifying the content of Ca(OH)-2 from cement-water system. The results indicate that the model established is valid and can be applied well.
