Abstract
Background/Objectives: The aim of the present study was to examine the performance of reinforced concrete beams strengthened by ferro cement technique. Methods/Statistical Analysis: In this experimental investigation five beams of rectangular cross section were cast using M25 (1:1.48:2.52) normal mix and high strength deformed bars as longitudinal and shear reinforcement. The beams were retrofitted for two conditions. In one case, the beams were stressed to 70% of the failure load and than they were retrofitted. In second case, for overloading the unstressed beams were retrofitted. Findings: The results obtained indicate that the increase in ultimate load was 70% in overloading case and 45% in stressed beam, also there was reduction in rotation and deflection. Application/Improvements: It was concluded from the experimental investigation that the strengthening of reinforced concrete beams by ferro cement technique is practicable and has considerable advantages.
