A Three Dimensional Microstructure Sphere Model of Cement Hydration

Abstract:

A microstructure kinetic model is introduced for the hydration of cementitious materials.The hydration degree is mainly controlled by chemical reaction or diffusion rate in hydrate process of cement. According to evolution of characteristic parameters in two main processes, the hydrated kinetic equations is given in the paper. The kinetic equations can simulate the main hydrated processes, and an understanding on the hydration mechanism of cement can be emphasized. Chemical reaction dominates in the early stage of hydration, diffusion rate becomes the dominating factor gradually as the hydration degree increases.
