| 摘 要： | 对不同水灰比及掺加粉煤灰、硅灰的高性能混凝土氯离子扩散系数进行了试验研究,并对高性能混凝土海洋平台结构抗氯离子侵蚀耐久寿命进行了预测和分析,结果表明在一定条件下,低水灰比和增加保护层厚度均可以提高混凝土结构抗氯离子侵蚀的耐久寿命.该结论为混凝土海洋平台结构的耐久性设计与评估提供了参考依据.

| Abstract: | Chloride ion diffusion coefficient for high performance concrete(HPC) was experimented and studied in different water cement ratios and different contents of fly ash and silica.Then durable life of offshore HPC platform structures resisting chloride ion penetration was predicted and analyzed.It is shown that durable life of concrete structures resisting chloride ion penetration is extended under lower water cement ratio and thicker protective layer,which will be helpful and useful for durability design and assessment of concrete offshore platform structures. |

| Keywords: | offshore platform chloride ion penetration high performance concrete(HPC) diffusion coefficient life prediction |
