This paper describes results from studies on effects of superficial strengthening with FRCM system on compressive strength of autoclaved aerated concrete (AAC) masonry. Tests were carried out on models with one vertical crack and without crack. The research program included walls without any strengthening, strengthened at two or four sides. In addition, models with additional anchorage of superficial strengthening by steel plates were tested. Strengthened masonry did not demonstrate an increase of compressive strength and deformability. Increased deformability was observed for circumferentially strengthened masonry.
