This study develops three-dimensional mesoscale concrete models consisting of mortar and realistically shaped coarse aggregates. The weighted discrete Voronoi tessellation is applied to generate coarse aggregate models. The grain size and shape distributions are adjusted to reproduce those of an actual concrete sample. The validity of the proposed method is confirmed by comparing the mesoscale model to a concrete sample.
