Title: CFRP Repair of Corroded Girder: Four Years of Service

Abstract:This paper presents a field application on the use of Fiber Reinforced Polymers (FRP) to repair a corrosion-damaged reinforced concrete (RC) girder. Concrete surface rehabilitation and Carbon FRP (CFRP) repair was undertaken on a 9.75 m (32 ft) long section of the 22.86 m (75 ft) long girder at the south span of the Scheifele Bridge, in the Regional Municipality of Waterloo, Ontario. Four different repair schemes were utilized along the length of the girder. The different steps of the rehabilitation work are described including surface preparation, application of the CFRP sheets, and installation of sensors as part of the structural health monitoring system. The sensors comprised of electrical strain gauges, corrosion probes and fiber optic sensors placed at critical locations along the bridge girder. Visual inspection and analysis of the data gathered over the last four years showed that the FRP repair system was able to halt the existing corrosion activity and protect the structural integrity, thus prolonging the bridge service life.
