Paper Title:
Cellular Automata-Based Chloride Ion Diffusion Modelling of Concrete Bridge under Multifactor Coupling Action
  Abstract

In order to accurately simulate the diffusion of chloride ion in the existing concrete bridge and acquire the precise concentration of chloride ion at any time, a Cellular Automata(CA)-based model is proposed. Firstly, the process of chloride ion diffusion is analyzed by the CA method and a nonlinear solution to the Fick’s second law is obtained. Secondly, considering the impact of various factors such as stress states, temporal and spatial variability of diffusion parameters and water-cement ratio on the process of chloride ion diffusion, the model of chloride ion diffusion under multifactor coupling is presented. Finally, a chloride ion penetrating experiment is used to prove the effectiveness and reasonability of this present method. A T-type beam is taken as an illustrative example to analyze the process of chloride ion diffusion.
