Abstract: An experimental study was undertaken to evaluate the performance of fiber-reinforced self-consolidating concrete and equivalent SCC mortar containing different types of fibers in repair of beam elements. Three 200 x 400 x 2300 mm monolithic beams were prepared and used as reference specimens. One beam was cast using ordinary concrete, the second with SCC, and the third with fiber-reinforced SCC. Six beams were also cast with ordinary concrete in which a damaged zone having different thicknesses was provided to simulate a tensioned repaired zone. The beams were repaired with SCC and fiber-reinforced equivalent SCC mortar of different compositions and tested in flexure. Test results showed that adequately proportioned SCC and equivalent mortar with and without fibers can successfully restore the load capacity of damaged beams. The use of steel-fiber equivalent SCC mortar exhibited proper ultimate load capacity and stiffness response.
