Abstract :

► We propose a patch repair method that uses HPFRCC to repair deteriorated RC members. ► Under service conditions, the HPFRCC remains impermeable even if they have cracks. ► The strength of beams could be recovered if the corrosion amount was less than 10%. ► A combined use of a fiber net with HPFRCC improves the dispersibility of cracks.
