REPAIR OF STEEL REINFORCED CONCRETE WITH CARBON/EPOXY COMPOSITES

摘要

This paper focuses on repair of reinforced concrete with externally bonded carbon/epoxy composite sheets. The efficiency of repair was evaluated by flexural tests. The results showed that repairing steel reinforced concrete by externally bonding carbon/epoxy composite sheets can restore the strength of the samples. Accelerated environmental exposure by water immersion for 60 days had slight positive effect on the load bearing capacity. Whereas hot-cold cycles for 60 days and long term outdoor exposure up to 28 months reduced the load bearing capacity for about 7%.
