Prediction of Equivalent Chloride Ion Diffusion Coefficient in Cracked Concrete of the in-Service RC Element

Considering the influence of visible load-induced transverse cracks on chloride ion diffusion in cracked concrete in-service reinforced (RC) elements under marine environment, a typical volume with one crack was taken to establish governing equation. Assuming widths at outer lateral and bottom surfaces were equal, model predict equivalent coefficient put forward consider average width, spacing extending lengths beam height width directions diffusion. Results show that proposed can better reflect variation trend different RC environment.
