Abstract

Abstract: In order to study the bond behavior between basalt fabric reinforced polymer-fiber reinforced cementitious matrix (BFRP-FRCM) composite layer and aerated brick, the single-shear tests on BFRP-FRCM composite layer strengthening aerated bricks were conducted by considering the fibers mixed in cement-based materials, the bonding length of composite layer and the layer quantities of BFRP fiber meshes. Based on the tests results, fibers, bonding length and layer quantities influencing the bonding behavior between composite layer and block were explored. It presented that the BFRP-FRCM composite layer can significantly improve the tensile capacity of aerated brick. The bonding capacity of the composite layer becomes larger with the increase of bonding length. When it reaches the maximum value, it gradually gets smaller, i.e., the bonding length of the composite layer has an optimal value. Increasing the quantity of basalt mesh layers can increase the tensile strength of the specimen, but the bonding behavior and the utilization ratio of tensile strength will decrease. Comparing with the specimens strength with polyethylene layer, the specimens strengthened with polyvinyl alcohol layers exhibited better ductility.
