- Abstract
By adopting seven kinds of adhesive resins, the mechanical properties of the interface between pultruded Basalt fiber reinforced polymer plates and cast-in-place concrete is studied according to two groups of stretching double-shear test. And it is compared with the dry-bonding interface between BFRP plates and the precast concrete. Further study is conducted by comparing the damage features, load-displacement curves, effective bond length, bond slip relationship and interface fracture energy between the two interfaces. It is found that the effective bond length of the two interfaces are similar, but the bond strength of the wet-bonding is about half of the dry-bonding. Finally, the shear stress-slip model is proposed for the wet-bonding interface based on the experimental data.
