This study was aimed at exploring the durability of concrete revetment materials at the water-level-fluctuations zone of the Yellow River Delta Wetlands. The simultaneous effect of mineral admixtures (i.e., fly ash, slag, and silica fume) and polypropylene fiber on the resistance of concrete revetment materials to chloride erosion, was presented. Under the artificial simulation environment of dry-wet cycles and chloride ion (Cl⁻) erosion coupling, the evolutions of macro-mechanical properties and the microscopic composition of mineral admixtures-fiber-blend concrete was investigated via compressive strength tests and X-Ray Diffraction (XRD), Mercury Intrusion Porosimetry (MIP) test, for durations of 120 days. The results showed that, under the long-term dry-wet cycles and chloride ion coupling erosion, fly ash and slag provide additional Al₂O₃ to react with Cl⁻, and tend to produce Friedel’s salt with smaller interlayer spacing, thereby realizing concrete possessing higher chemical binding capacity with Cl⁻. The improvement in the physical adsorption capacity of concrete with Cl⁻, which was due to the formation of additional hydration products of calcium-silicate-hydrate (C-S-H) gel. These materials showed exhibited good resistance to dry-wet cycles and Cl⁻ erosion resistance, and thus were deemed to be suitable for the preparations of concrete revetment materials at the water-level-fluctuations zone.

这项研究旨在探讨黄河三角洲湿地水位波动区的混凝土护坡材料的耐久性。提出了矿物掺合料（即粉煤灰，矿渣和硅粉）和聚丙烯纤维对混凝土护坡材料抗氯化物侵蚀的同时作用。在干-湿循环和氯离子的人工模拟环境（CL ^-）通过抗压强度测试和X射线衍射（XRD），水银压入孔隙率法（MIP）测试研究了侵蚀耦合，矿物掺合料-纤维混合混凝土的宏观力学性能演变和微观组成，历时120年天。结果表明，在长期干-湿循环和氯离子耦合侵蚀下，飞灰和炉渣提供额外的Al ₂ ö ₃与氯反应^- ，并且往往会产生弗里德尔的盐与层间距变小，从而实现混凝土与氯具有较高的化学结合能力^- 。与氯混凝土的物理吸附能力的提高^-，这是由于形成了硅酸钙水合物（CSH）凝胶的其他水合产物。这些材料显示出表现出对干-湿循环和Cl良好的抗^-抗侵蚀性，因此被认为是适合于混凝土护岸材料在水-电平-波动区的准备工作。
