Corrosion of embedded reinforcing steel and the complication of concrete structures is a worldwide problem. Damages due to corrosion reduces the service life of structures and can create serious problem. Visual inspections are not effective for knowing the initiation of corrosion because most of the damage remains observed until cracking and spalling of the concrete occur. Traditional techniques for determining the presence and rate of corrosion are expensive and difficult to find out. The sensors would be installed in new construction or in new portions of rehabilitated structures. The positioned of reinforcing steel adjacent before concrete placement. If corrosion is detected, an owner can take action against corrosion and pretend the service life of the structure. In this project, corrosion expansion sensors were used to monitoring the rate of corrosion in reinforced concrete beam with the help of strain calibration experiment, sensitivity measurement, corrosion mass loss rate and material composition with the help of Minitab software. It is not possible to take the long life result from traditional methods of monitoring the corrosion in structure but corrosion monitoring by using embedded sensors is improved the response latency. Experimental and analytical work used in this project gave the good comparative results for corrosion monitoring.
