EFFECTS OF WET-DRY ALTERNATION OF OCEAN TIDE ENVIRONMENTS ON THE BOND BEHAVIOUR OF CFRP-REINFORCED CORAL CONCRETE
In this paper, the dry-wet cycle test in NaCl solutions is used to simulate ocean tide attack, and the pull-out test is carried out to explore the changes in the bond behaviour of CFRP-reinforced coral concrete under the attack of the simulated ocean tide environment.

| description | In this paper, the dry-wet cycle test in NaCl solutions is used to simulate ocean tide attack, and the pull-out test is carried out to explore the changes in the bond behaviour of CFRP-reinforced coral concrete under the attack of the simulated ocean tide environment. As shown by the results, with the increase in the number of dry-wet cycles, the bond strength of CFRP-reinforced coral concrete will first increase and then decrease. Based on damage mechanics theory, the deterioration of the interfacial bond properties between CFRP bars and coral concrete under the attack of the ocean tide environment is analysed. By fitting the obtained data, the bond-slip equation of the CFRP-reinforced coral concrete with different damage degrees is obtained, and the related bond-slip constitutive model considering damage effects is established. |
