영어 초록
ber reinforced polymer (FRP) reinforcing bars for concrete structure have been extensively investigated and a number of FRP bars are commercially available. However, major shortcoming of the existing FRP bars is low elastic modulus compared to conventional steel bars. Because of these reasons, FRP Hybrid Bar which have the concept of material hybridization(synthetic resins, deformed bar, glass fiber etc) for concrete structures have been developed. One of main features of this bar is corrosion resistance and this is important to confirm this anti-corrosion capacity of FRP Hybrid Bar. In this study, galvanic corrosion current behavior of 3 types of specimens, including two types of FRP Hybrid Bars and one conventional steel rebar, was investigated under the 0%, 1.5%, 3% and 6% salt water ratio condition. The result of this study can be used to evaluate the applicability of FRP Hybrid Bar to concrete structures.
