Bond behavior between GFRP bars and seawater sea-sand fiber-reinforced ultra-high strength concrete

To tackle the challenge of steel corrosion in conventional reinforced concrete (RC) structures, particularly in maritime environment, the implementation of glass fiber reinforced polymer (GFRP) bars in seawater sea-sand concrete (SSC) structures becomes increasingly popular due to their excellence corrosion resistance. However, the bond characteristics of GFRP bars in fiber reinforced ultra-high strength SSC have not been explored. To this end,...
