| 采用交流阻抗谱方法研究了在海水侵蚀条件下不同强度等级混凝土试件的钢筋锈蚀情况；通过复导纳图求得了反映钢筋锈蚀特性的全部阻抗参数，并分析了在海水中浸泡的时间对这些参数的影响．结果表明：随混凝土强度等级的增大，混凝土的抗钢筋锈蚀能力亦增大． |

| Abstract: |
| AC admittance technique was used in the measurement of the impedance parameters of the corrosion of rebar of the concrete. The effect of seawater on the corrosion of rebar in the concretes with different strength grade was studied. The results show that the capacity of the anti-corrosion of rebar increases with the increases of the compressive strength of the concrete. |
| Key words: compressive strength,corrosion of rebar,impedance parameter,complex admittance |
