To investigate the mechanism of concrete cracking by rebar corrosion, an accelerated test by electrolytic corrosion has been done. Additional chemical analysises were also carried out to confirm corrosion characteristics. During acceleration, free chlorides moved toward the anode and corrosion products did not move away from the steel-mortar interface. X-ray diffraction results indicated that corrosion products consisted mainly of Fe3O4. Not only resistance of concrete against internal pressure but also corrosion rate had influence on weight-loss of steel for cracking. When the corrosion rate was more than 0.5mpy, 3-9mg/cm2 of weight-loss was enough for cracking and an elastic analysis was effective for its presumption.
