Abstract: Base on the digital image,a model was formed to describe thecement hydration and microstructure. Many important factors, such as powder size distribution, phase volume fractions, phase surface area fractions, and diffuse capacity have been considered in the model. Thus the properties， such as percolation, mechanical and transport, are easily computable.The hydration process can be modeled, and the cement intension predicted by this model.Some new ideas in the future research were presented lastly.
