Abstract
- This paper presents the results of an experimental study designed to investigate the viability of using externally bonded carbon-fiber-reinforced polymer (CFRP) wrap to extend the service life of corroded reinforced concrete beam. The beam cast with design mix of M30 are used in this project.Procedures to induce corrosion using impressed voltage technique. Samples were evaluated for corrosion activity by monitoring corrosion potentials and impressed current flow levels also flexural behaviour of carbon fibre reinforced beam is compared with conventional beam.
