This paper studies the axial compression test through 8 groups of reinforced brick masonry specimen of 5 different horizontal fiber rates and 3 vertical fiber layer forms. The preliminary test results show that: CBF Mesh Reinforced Brick Masonry has a good reserve of strength, and the ductility and axial compressive strength have been improved significantly, comparing to the unreinforced brick masonry. The failure modes of the specimen and the stress mechanism are analyzed, and the influence on masonry compressive properties of horizontal fiber ratios and that
