Abstract：Based on the center-particles hydration dynamic model proposed by K.B.Park,the micro-structural hydration model of Portland cement was built considering two factors which were characteristics of inner and outer hydration products as well as the decrease of the hydration rate due to the reduction of free water and the reduction of the interfacial area of contact between the free water and hydration products.The model was used to predict the variation relationship of the hydration rate with the change of hydration degree.The results show that in the whole cement hydration process the revised micro-structural model can simulate the relationship between the cement hydration rate and hydration degree well.
