摘要：
Corrosion of reinforcement due to chloride penetration is one of the major deterioration mechanisms in concrete structures. The focus of this research was to investigate the comparison between the crack width and length and the non-steady-state chloride migration in concrete with artificial cracks. One concrete was used. The experimental results were compared with diffusion simulations. There was indication of consistency between the length and width of cracks and between the length of cracks and migration. The migration depth below the end of crack was independent from the width of crack. The simulation of chloride diffusion was similar to migration tests.
