Reinforcement in masonry structures is used to reduce cracks' width and increase the load-bearing capacity of walls. The article describes the study of autoclaved aerated concrete (AAC) walls in a full scale. A new type of steel mesh reinforcement was used in the tests. The influence of the reinforcement on the zone around the window was determined. The presented research is a continuation of previous similar analyzes published in Building Materials [1, 2].The obtained tests results were compared with the results published in [1, 2, 3].
