This paper presents an experimental study on the pre-cracked reinforced concrete beams repaired with sealant injection method. The purpose of this study is to evaluate the flexural and shear capacity of the repaired beams. Due to this purpose, totally six beams consisting of three beams for flexural and three beams for shear investigation were prepared and tested. Two beams indentified as control specimens were tested until failure. While the others were pre loaded until 50% and 90% of yield load (in case of flexural) and ultimate load (in case of shear). The cracks in pre-cracked beams were injected with sealant injection method at selected locations. Then, after 24 hours the repaired beams were again tested until failure. Test results showed that stiffness of the beams after pre load is slightly increase compare to that initial specimen. In addition, the flexural and shear capacity of the repaired beams slightly increase compare to that control specimens.
