| Abstract: | The effect of aggregate shape on the chloride diffusion coefficient of concrete is analyzed.A numerical method for predicting the chloride diffusion coefficient of concrete with aggregate shape is presented.By combining the computer simulation technique with the Monte-Carlo numerical integration algorithm,the area fraction of interfacial transition zone in concrete with octagonal aggregate particles is obtained.By comparing with two sets of experimental results,the validity of the proposed numerical method is verified. |

| Keywords: | concrete aggregate shape diffusion coefficient of chloride ions percentage of interfacial area finite element method |
