Rehabilitation of Damaged Reinforced Concrete Beams

Abstract

The concrete structures are often exposed to damaged as a result of several factors including, environment, design, and other factors, and because of the high cost and long time needed for reconstruction of the damaged buildings, it become necessary to consider techniques for rehabilitation of the damaged structural members in the building. 12 reinforced concrete beams (2200x200x150 mm) were cast and tested under point load at mid-span to limit the failure. Several techniques for repairing the damaged beams are carried out in the present work. Ferrocement composite, steel plate, fiber carbon reinforced polymer (FCRP), nano cement composite, and the injection of the developed nano cement mortar are considered.
