This paper is an attempt to summarize what has been developed in the modelling of cement hydration and microstructure. In the study, a physically realistic microstructure was built on a computer and operated by various algorithms (finite difference, finite element, random walk, etc .)to predict physical properties. Some new ideas for future research are presented.
