摘要：

To simulate a concrete exposed to chloride environment, this study uses a numerical solution for one-dimensional diffusion equation to solve a non-steady one-dimensional diffusion equation considering three different diffusion coefficients D(v), D(t) and D(v,t). These numerical results served as a handy tool to understand the actual influences of different types of diffusion coefficients on the physical diffusion process with chloride.
