The use of external reinforcement based on carbon fibers is technically and economically justified to strengthen concrete structures, which is confirmed by years of experience. The use of this method of reinforcement for masonry structures has significantly less history and, accordingly, experience. However, experimental and site specific efficacy of the use of external reinforcement in the amplification of the pillars of masonry by the device holder has been proven. The experiments of strengthening of a brickwork carried out earlier, as well as the developed theory of calculation, concern application of a full-bodied brick. Given the volume of construction of large-format ceramic stone, the task of strengthening structures from it becomes more urgent every year. In order to solve this problem, the present experimental studies were carried out – experimental studies of the clip effect on the fragments of brickwork with the strengthening of the external reinforcement system based on carbon fibers. In addition to studies of the influence of the size of bricks and the presence of voids, there was a study of the possibility of strengthening the samples with a cross-section size ratio of more than 2. In this case, carbon through anchors were mounted in the Central part of the samples. The test results obtained characters of destruction of specimens, the ultimate load-bearing capacity, made the appropriate conclusions.
