description A simulation model to estimate the pore structure of cement hydrates is presented. In this paper, procedures for predicting phase compositions based on the classical hydration model of Portland cement, calculating the particle size distribution of constituent phases and evaluating the pore size distribution by stereological and statistical considerations are described. To evaluate of effectiveness of this model, simulation results were compared with experimental results of the pore size distribution measured by mercury porosimetry. As a result, it was found that the experimental and simulated results were in close agreement and simulated results indicated characterization of pore structure of cement hydrates.
