| Abstract | ||
| Reinforced concrete beams for high-strength concrete often exhibit structural and nonstructural cracking due to variety steel reinforcement. Four reinforced concrete beams with dimensions of (120*230*2550)mm were investigated. Beams (1&2) have tensile steel ratio (0.0099), while beams (3&4) have tensile steel ratio (0.018). Deflections were measured at first third, second third and mid span for original repaired beams using dial gauges with accuracy 0.01 mm. The repair strength achieved for risen epoxy injection high-strength reinforced concrete beams was shown similar that original beams, but a little deference. The failure load for repaired beams higher than original beams. | ||
