Dynamic model of temperature rise caused by cementitious materials hydration

This paper presents a dynamic model of temperature rise caused by cementitious materials hydration based on the basic nature of chemical change. There are many models for computation of temperature rise caused by cementitious materials hydration, but the most takes this temperature rise as a function of concrete age only, which does not consider the impact of initial temperature and temperature rise during hydration and thus cannot reflect the real course of temperature rise. This model not only accords with the general law of chemical change, but also coincides well the experimental data and stimulates well the actual course of temperature rise of concrete under any initial temperature.
