MATHEMATICAL MODELING OF CEMENT HYDRATION PROCESS AND MICROSTRUCTURE DEVELOPMENT

摘要：

In this research, a mathematical model of cement hydration process and microstructuraldevelopment was developed. A cubic hydration cell, which is composed by unreacted cementparticles, hydration products and free water, is presented to describe the microstructuraldevelopment of cement particles. The kinetics of cement hydration are given as the drivingforce 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 mathematicalmodel can present the cement hydration process more detailed in such a simple way. Thecomparison between numerical and experimental results proves that the newly developedmodel is quite effective and potentially useful for predicting the hydration and mierostructureof cement paste.
