On the Development of Monitoring Technique for Rebar Corrosion in Concrete using Sensor

부식센서를 이용한 콘크리트 철근부식 모니터링 기술 개발 연구

By introducing corrosion monitoring techniques, steel corrosion in concrete may be evaluated at early stage. The monitoring probes in concrete detect the causes (chlorides and $CO_2$) of steel corrosion by being cast into the concrete or diffusing in from the outside. Various systems for corrosion monitoring in concrete are reviewed in this paper. These techniques are classified according to monitoring purposes such as corrosion potential or corrosion rate of steel and causes for corrosion etc.. Today, special interests are converged in development of corrosion sensor as a monitoring method of new concept.
