The concrete is one of the oldest materials used in the building industry for ages. The models of this material are often designed to capture the behaviour of real constructions. To use these kinds of models the loading curves and basic experimental tests are needed. Since these experiments are expensive and often time consuming there is a new trend of replacing them by virtual numerical tests. This paper concentrates on one particular step towards developing such virtual laboratory – construction of a suitable representative volume element (RVE). Preliminary results addressing the influence of grain size distribution and their discretization inside RVE on finite element simulations of compressive damage of concrete sample are discussed.
