中文摘要：
通过海洋潮差环境条件下的现场侵蚀试验,研究了不同配合比水工砂浆的抗氯离子侵蚀性能。研究结论表明,随着侵蚀时间的延长,砂浆的氯离子扩散系数逐渐降低;相同侵蚀时间,水灰比越大,砂浆的氯离子扩散系数越大;以侵蚀360d的试验测试得到的砂浆氯离子扩散系数时变模型,可较好地预测之后的扩散系数和氯离子浓度。
英文摘要：
According to the onsite corrosion test under the marine tidal environment, the resistance performances of chloride ion cor- rosion of different mix proportion hydraulic mortar are studied. Analytic results indicate that the chloride ion diffusion coefficients are decreasing with the erosion time prolonging, and at the same erosion time, the chloride ion diffusion coefficients are increasing with the water cement ratio increasing. The time-dependent models about chloride diffusion coefficients are deduced by the erosion test of 360 days, it can predict well the later chloride diffusion coefficients and chloride ion concentrations.
