초록

The bonding of steel bar to concrete is closely related to the roughness and corrosion degree of steel bar surface. The accelerated corrosion of concrete specimens with different reinforcement diameters was carried out in this test. Through the pullout test of the corroded concrete specimens, the relationship between the bond stress and the displacement of the corroded concrete specimens under the corresponding corrosion degree was obtained. The bond stress of reinforced concrete with different size and corrosion degree are compared and analyzed to find out the influence of corrosion on the bonding property of reinforced concrete.
