Flexural Capacity of RC Beams Strengthened with SRP and SRG
The use of externally bonded Steel-Reinforced Polymer (SRP) and Steel Reinforced Grout (SRG) composites is a promising new technology for increasing the flexural and shear capacities of reinforced concrete (RC) members. The reinforcement system in these composites is a sheet made up of unidirectional cords consisting of tightly wound ultra high strength steel wires. The reinforcement can be molded into resin systems (SRP) or cementitious grout (SRG). This study is aimed at investigating the flexural strength improvement and performance of RC beams with externally bonded SRP and SRG. Eight specimens were tested under four-point bending with variables considered including the level of internal reinforcement, the number of external reinforcement plies, as well as the types of bonding agents.
