Abstract :
Corrosion assessment of the steel bar in reinforced concrete (RC) structures is a very urgent for the structural health monitoring and life-cycle design in civil engineering. Half-cell potential map and guard ring techniques are applied as typical qualitative and quantitative methods to assess the corrosion status, respectively. A RC panel has been formed to be an actual testbed to verify the effectiveness of these techniques. Its potential map and corrosion rate have been investigated by the electrochemical sensors before and after NaCl solution injected, respectively. The results indicate the corrosion status of RC panels can be identified effectively.
