ABSTRACT

A total of 7 reinforced concrete beams were tested in this study as summarized in Table 1. Beam C(0%) was a control beam with no corrosion, while beams C (5%) and C (7.5%) were control beams with 5% and 7.5% corrosion (mass loss in reinforcement). Beams S (5%) and S (7.5%) were repaired by applying CFRP

Every year building owners and managers are faced with the costs of repairing concrete that spalls when the reinforcing steel corrodes, usually due to the presence of salt. Removal, patching and the application of waterproofing membranes are some of the treatments that, alone or in combination, have traditionally been used to rehabilitate corrosion-damaged concrete. Steel corrosion is a major cause of deterioration which disrupts the cover zone of reinforced concrete. As steel corrodes, there is a corresponding loss in cross-sectional area and in turn reduction in the flexural strength capacity.
