Highly hollow masonry units, which allow reducing the weight of masonry constructions and improving heat and sound insulation qualities, are commonly used in masonry construction. Filling the hollows with concrete, or concrete with light additives, results in complex masonry. Overall performance of such masonry is affected by initial stresses, which are caused by shrinkage deformations of different infill concrete and masonry units. Behaviour of infill concrete and concrete blocks is analysed by applying numerical detailed micro modelling. Experiments revealed that masonry deformations of blocks with concrete filled hollows are similar to those of longitudinal deformations of infill concrete samples. σ-ε relations were received through numerical micro modelling and compressive strength of masonry match values were estimated during experiments.
