In order to describe and reconstruct the true irregular particle morphology of cement particles and clarify the hydration process, microstructure evolution and mechanical property development of cement-based materials, an irregular particle reconstruction method was proposed by a discrete method and a central growth model based on a cellular automata theory. A cement particle shape data-base was established. The irregular cement particles were introduced into the CEMHYD3D model, and an irregular basis hydration model was constructed. The effect of particle shape on the hydration process and pore characteristic parameters were analyzed. The reliability and accuracy of the hydration model after the introduction of irregular cement particles were verified. The total porosity and pore size range of the non-spherical-based model are smaller than those of the spherical-based model, while the specific surface area with various pores of the non-spherical-based model is greater than that of the spherical-base model.
