Pore Structure Model of Hydrates Comprising Various Cements and SCMs Based on Changes in Particle Size of Constituent Phases

A simulation model to estimate the pore structure of cement hydrates is presented. This paper describes 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. To evaluate the 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 the simulated results indicated characterization of the pore structure of cement hydrates.
