Abstract : Some concrete structures exposed to severe environmental conditions which might require maintenance or
strengthening. In this study, Reactive Powder Concrete （RPC）was used to investigate the effect of strengthening concrete
members by fire-damage test or freeze-thaw test. The results show that the mechanical properties of RPC possess high
strength, toughness, and freeze-thaw resistance. The CFRP (carbon fiber reinforced plates) wrapping specimens exposed at
300 ℃ showed totally failure with the deterioration of the adhesive. The RPC with bonding 10 mm thickness specimens
exposed at 400 ℃ still in good shape. The RPC with 1-cm or 2-cm thickness on strengthening concrete members could be
obtained specific retrofit effects. The performance of RPC specimens is better than those of CFRP wrapping specimens during
high temperature exposure.
