There is a great potential of ferrocement for strengthening reinforced concrete member. Ferrocement can be an excellent material in engineering construction. This method should be investigated and compared with conventional reinforced concrete. The beams were designed to have deficiency in shear, while strengthened beams were expected to fail in flexure. The experiments were planned to determine the load capacity and deformation of strengthened beams which were tested in static loading. The observation includes the failure mode of the beam as well as crack pattern on surface main beam and ferrocement panel. It was instructive to compare behavior between ferrocement panels and original beams.
