Recently, the computer technology has been used in many engineering fields. And numerical simulation has been applied to the analysis on mechanical behavior of concrete. However, it is assumed that the concrete is a homogeneous material, though it is a composite material, with coarse aggregates and mortar as the main components. Then we proposed the generation method of concrete model in consideration of the coarse aggregate. This method is a quite new model, so it is created from the shape of any actual aggregates. Also, in this paper, Voxel element with the drilling degrees of freedom is proposed, and the stress condition within the concrete that is made by proposed method is calculated by the Voxel analysis which used this element. The analytical result became excellent.
