Abstract: In this research, a mathematical model of cement hydration process and microstructural development was developed. A cubic hydration cell, which is composed by unreacted cement particles, hydration products and free water, is presented to describe the microstructural development of cement particles. The kinetics of cement hydration are given as the driving force of the model. Although the cement particle size distribution is introduced in the model, the specially designed hydration cell can still keep its individual properties. The mathematical model can present the cement hydration process more detailed in such a simple way. The comparison between numerical and experimental results proves that the newly developed model is quite effective and potentially useful for predicting the hydration and microstructure of cement paste.
