Abstract: An investigation has been carried out to determine the effects of bonding composite patch to cracked concrete beems on the flexural properties and to evaluate repairing procedures for pactical application. The overall performance of the repaired beams was better than that of the baseline beam in terms of flexural properties. The wet layup long patch gives the best improvement in flexural modulus, yield strength and ultimate strength by 48%, 26% and 14% respectively. Wet layup technique gave better mechanical properties than the precured patch. The tested repaired specimens exhibited the predominate shear failure in the concrete and this indicated that shear strengthening of concrete beam could substantially increase the overall structural integrity of the beam.
