Retrofitting refers to the addition of new members or components to older systems. In terms of civil engineering it refers to the strengthening of old structures. Many of the existing reinforced concrete structures do not meet the current design standards because of inadequate design and construction or need structural upgrading. They are in urgent need of repair, retrofitting or reconstruction because of fail or collapse due to various factors like corrosion, lack of detailing, failure of bonding between beam-column joints, increase in service loads, etc., leading to spalling, cracking, loss of strength, deflection, etc. Innovative techniques for repair have many advantages over conventional techniques. This paper presents the behavior and strength of reinforced concrete beams and columns strengthened with Ferro cement jackets. A total 15 beams were prepared from that three specimens of beams and columns are control beams. Remaining twelve beams are distressed at 60% and 80% of the ultimate load and retrofitted with Ferro cement in no of layers single and double layer respectively. The load deflection characteristics and mode of failure are studied. The test result indicates that load carrying capacity is increases after retrofitting.
