摘要：
To investigate the diffusion of sulfate ions in coral seawater concrete under the mechanism of the wetting-drying cycle of sulfate solution, the concentration of sulfate ions in coral concrete at different depths under different cycling cycles was tested in this experiment. Finite-element numerical simulations were then carried out using COMSOL software. The results showed that the sulfate ion concentration in the concrete at the same depth increased steadily with time, and the erosion depth also increased. The numerical simulations successfully reproduced the diffusion of sulfate ions in coral seawater concrete under the mechanism of the wetting-drying cycle of sulfate solutions.
