Abstract：To investigate the chloride transport behavior in cracked concrete under dry-wet cycles,a chloride convection-diffusion model for non-penetrating cracks in concrete was developed using the Laplace transform.The effects of crack width and depth on the chloride content distribution was analyzed and the relationship between crack parameters and surface chloride content was established in the model.The results indicate that as the crack width and depth increase,the accumulation of surface chloride in concrete accelerates,thereby enhancing chloride transport.Compared with existing models,the proposed theoretical model improves prediction accuracy by 30%.
