To investigate the rule of reinforcement corrosion and service life of coral concrete CAC structure under the coupling effect of bending stress and Marine environment, this paper carried out bending stress loading tests on coral concrete members with homemade equipment, and studied the influence of bending stress on different types of reinforcement corrosion under different protective layers in coral concrete. ABAQUS finite element analysis software was used to simulate the stress magnitude and stress state of reinforced coral concrete member model under bending stress. The corrosion of various types of steel bars under bending stress was analyzed using polarization curves and electrochemical impedance spectroscopy.

To investigate the rule of reinforcement corrosion and service life of coral concrete CAC structure under the coupling effect of bending stress and Marine environment, this paper carried out bending stress loading tests on coral concrete members with homemade equipment, and studied the influence of bending stress on different types of reinforcement corrosion under different protective layers in coral concrete. ABAQUS finite element analysis software was used to simulate the stress magnitude and stress state of reinforced coral concrete member model under bending stress. The corrosion of various types of steel bars under bending stress was analyzed using polarization curves and electrochemical impedance spectroscopy.
