Aluminum alloy has the advantages of light and high strength, good ductility, low temperature brittle fracture sensitivity, corrosion resistance, easy forming and so on. It can be used for strengthening concrete structures under corrosion and cold conditions. In this paper, based on the study of the bond-slip behavior of the interface between aluminum alloy and concrete under double shear test, the double shear tests of 45 members are carried out, and the strength grade of concrete and the surface roughness of aluminum alloy slab are analyzed. The effect of bond length and width on bond interface failure mechanism, peeling capacity and load-slip curve of aluminum alloy plate. The results show that the interfacial stress is gradually transferred from the loading end to the free end during loading, and with the strength grade of concrete. With the increase of bonding length and width of aluminum alloy plate, the peeling capacity of the specimen is also increased. However, there exists an effective bond length value for the bonding length of aluminum alloy, and the peeling capacity of the specimen above the value will not be increased, and the surface roughness of aluminum alloy has no substantial effect on the increase of the peeling capacity of the specimen.The bond slip test curves of aluminum alloy plate and concrete under different parameters are obtained by measuring the strain of aluminum alloy plate. The results show that the curve has obvious interfacial softened characteristics and nonlinear behavior, which can be used to guide the practical engineering design of aluminum alloy plate strengthened concrete.
