摘要: |
在讨论应用交流阻抗谱方法测量混凝土中氯离子扩散性的基础上,对所观察到的在某些粉煤灰混凝土中氯离子扩散的特有阻抗谱进行了理论分析,并指出这种以双曲正切曲线为特征的阻抗谱是由粉煤灰掺入而导致的有限扩散层所引起的。 |

Diffusion of Chloride in Fly Ash Concrete |

Abstract: |
In measuring the diffusion of chloride in concrete, the impedance spectra of some fly ash concretes due to the diffusion of chloride are reported and theoretically analyzed. It is indicated that the hyperbolic characteristics of the impedance spectra may be attributed to the finite diffusion layer due to the addition of fly ash. |
Key words: fly ash concrete,diffusivity of chloride,hyperbolic diffusion |
