Paper Title:
Durability of Broken Concrete Specimens Strengthened with CFRP Sheets
  Abstract

Carbon fiber-reinforced polymer (CFRP) composites are thin laminates that are externally bonded to broken concrete specimens using an epoxy system to increase their load-carrying capacity in this study. This paper reports the test results of broken concrete specimens strengthened with CFRP sheets and subjected to two aggressive environments including ultraviolet (UV) and freeze-thaw cycles. Test results revealed that three different CFRP layers are effective in retrofit on the broken compressive or flexural concrete specimens. The broken concrete specimens repaired with an epoxy and CFRP system could improve their compressive strength, flexural strength or ductility. Both aggressive environment tests didn’t cause obvious degradation to hardness index, compressive or flexural strength. The flexural specimens used half-U coating and anchorage systems were much higher strength than those only wrapped with CFRP sheets on the flat surface.
