摘要
通过试验对不同水胶比以及掺粉煤灰、硅灰的混凝土进行氯离子扩散系数测试,分析水胶比以及粉煤灰和硅灰等活性集料对混凝土结构抵抗氯离子侵蚀性能的影响。根据试验结果对混凝土结构抵抗氯离子侵蚀耐久寿命进行预测。此研究成果可为氯盐污染环境下混凝土配制及结构耐久性设计与评估提供参考。
Test study has been made of Chlorideion diffusion coefficient in concrete with different water binder ratio and different dosage of fly ash and silica fume.Influence on concrete performance against Chlorideion penetration caused by water binder ratio and dosage of fly ash and silica fume was analyzed.According to the test results,durable life of concrete structures was predicted against Chloride erosion.The results can be taken as a useful reference to concrete production against Chlorideion penetration as well as durability design and assessment of concrete structures in Chloride environment.
