Abstract

This paper presents an experimental investigation to predict the load-deformation behavior of High Strength reinforced concrete beams that failed in flexure and were repaired by epoxy injection. Four simply supported reinforced concrete beams with dimensions of (120*230*2550mm) were investigated after repairing with the epoxy resin injection method. Beams B1 and B2 have a tensile steel ratio of 0.0099, while Beams B3 and B4 have a tensile steel ratio of 0.0177. Deflections were measured at first third, second third from the support, and at mid-span for all beams by using dial gauges. The behavior achieved for resin-injected high-strength reinforced concrete beams was similar to that of the original beams. However, the cracks do not re-open after retesting. Instead, new nearby cracks are developed and the repaired beams showed a greater ductility than the original beams.
