摘要：

By using a simultaneous thermogravimetry (TG) and differential thermal analyzer (DTA), the hydration processes of the pure C3S and with the addition of Ca(NO3)(2) was followed. The peak temperature was determined and kinetic analysis on one of the hydration products, calcium hydroxide, was performed. Results show that the use of Ca(NO3)(2) increased the activation energy value of calcium hydroxide formed which is one aspect of the accelerating properties of Ca(NO3)(2) while there is no sign of hydration for the addition of sucrose which proved its retarding property. It was also shown that the activation energy increased when the hydrated pastes aged.
