Abstract: 
Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) exhibiting high tensile strength and ductility and low permeability is adapted to protect and strengthened existing reinforced concrete structures. The contribution of UHPFRC is not limited to a waterproof layer but it is extended to mechanical reinforcement. Furthermore, UHPFRC layer combined with passive reinforcement can increase the flexural and shear strength of a structure. In this paper, rehabilitation and strengthening of various reinforced concrete structures (building and bridges) with UHPFRC layer are presented and discussed. The rehabilitation and strengthening of existing reinforced concrete structures with UHPFRC layer is effective as it allows extending the lifecycle of a structure with limited cost.
