摘要: Abstract Repair and strengthening of reinforced concrete (RC) members in existing structures are very important to extend their service life. In this study, steel fiber high strength lightweight self-compacting (SHLSCC) developed by the authors is applied for RC beams improve bending moment capacities. There significant improvements stiffness strengthened as well 14 - 58% peak load when with 40 mm, 50 mm 60 mm layers SHLSCC. Application SHLSCC lower half (tension zone) beam increased its 33.1%. Results indicate that material may effectively be utilized structures.
