Research Abstract

To evaluate the influence of the restraint degree of concrete on bond stress behavior of RC member damaged by corrosion, expansion test using nonexplosive demolition agent was carried out. As a result, the thickness of cover-concrete and the compressive strength of concrete greatly influence the restraint degree of concrete and the restraint of concrete decreases exponentially as the increase of crack width of the concrete surface. Furthermore, the deterioration of bond characteristics due to restraint degree of concrete was formulated. This model includes the influence of the concrete strength, thickness of cover-concrete, pressure of the corrosion expansion and crack width of the concrete surface.
