A Study on Repair Materials and Mesh Bonding Techniques Used To Repair Concrete Beams Failed In Flexure

In this work it is proposed to study the behavior of repaired concrete beams. The effectiveness of various repair materials was studied. Also different repair techniques were tried and results were compared. Plain concrete beams of dimensions 150mm x 150mm x 700mm were casted. The beams were failed in flexure with two point loading. The failed beams were repaired using various methods and techniques. The repair technique adopted was external bonding of steel meshes of various types with various repair materials. Beams repaired with Epoxy + SBR + Cement (RESC) without any mesh bonding giving better results. Almost all the mesh bonding repair techniques adopted were giving more than 100% regain of load carrying capacity of the original beams.
