Abstract

Abstract

According to the primary channels and source of chloride penetrating into concrete, the mechanism is expounded.The kinds and their limitations of the existing calculating models are analyzed.After taking account of the effects on chloride diffusion coefficient of cement kind, mixed ratio, temperature, relative humidity and time, a calculating model of chloride penetrating into concrete based on finite difference is established.The model is better to reflect the actual situation, which has proper theoretical and practical value.
- chloride,
- erosion of concrete,
- calculating model,
- diffusion coefficient,
- finite difference
