Immersion solutions at different salt ratios and concentrations were prepared based on the seawater salt composition in Shenzhen ports, China. The effect of immersion solution on the deterioration of the mortar and the chloride diffusion coefficient were investigated. The results show that the influence of sulfate ions on the diffusion of chloride ions is related to the salt concentration in multi-ion solutions. The diffusion of chloride ions is inhibited by high-concentrated sulfate and magnesium ions in the early stage and promoted in the later stage. This phenomenon is not consistent with the effect of multi-ion interactions in the marine environment. The low concentration of sulfate and magnesium ions in seawater does not inhibit and even slightly promote the diffusion of chloride ions in the mortar.
