基于经典静电理论和能思-普朗克方程，提出了一种模拟水化水泥膏体或混凝土中电化学氯离子萃取过程中多组分离子迁移的简单方法。初步计算结果表明，该方法定性地再现了埋埋钢阴极周围孔隙溶液组成曲线实验研究中观察到的几个特征，但无法提供与实验数据一致的定量结果。
A simple method to simulate multicomponent ionic migration associated with electrochemical chloride extraction from hydrated cement paste or concrete has been proposed based on classical electrostatic theory and the Nernst-Planck equation. It has been shown from preliminary calculation results that the method reproduces qualitatively several of the features observed in experimental studies of pore solution composition profiles generated around embedded steel cathodes, but fails to provide quantitative agreement with the experimental data.
