Keywords:aggregates, concrete, meso-scale

This study creates meso-scale concrete models with realistic shaped aggregates in three-dimension. The coarse aggregates are modeled by Voronoi diagrams, and each of them is then arranged randomly without overlapping. The volume fraction, size and shape of aggregates obtained from the proposed model are compared with those of actual concretes. Good agreements are found between the numerical and actual concretes.
