Abstract

Cracking behavior due to rebar corrosion for concrete specimen with single rebar was evalu- ated experimentally and analytically. In the experiment, the propagation of crack was observed by the electric corrosion test. Three-dimensional Rigid- Body-Spring-Method (RBSM) with three phase material corrosion expansion model was applied to simulate internal cracking patterns, surface crack width propagation and in- ternal crack propagation. The effect of corrosion products properties and the penetration of corrosion products into cracks during the corrosion process were investigated and cracking behavior due to rebar corrosion was simulated reasonably. As the results, the mechanism of surface crack width propagation with internal crack propagation was clarified.
