Abstract: 
This study proposes a patching method using HPFRCC as a repairing technique for the RC member deteriorated by chloride-induced corrosion. The deteriorated cover concrete in RC beams was removed as far as to the backside of the tensile rebar with a water jet, after which HPFRCC was overlaid by shotcreting. The effects of combined use of a fiber net and HPFRCC on the mechanical performance of the beams were also investigated. Patching repair with HPFRCC proved to be effective to recover reduced yield strength and ultimate strength of the deteriorated beam.
