摘要

钢筋锈蚀的主要原因是氯化物的渗透,尤其是在基础设施结构中,氯化物的渗透会导致钢筋的高锈蚀率。快速氯化物迁移(RCM)试验是评估混凝土和砂浆抗氯化物渗透性的常用加速试验方法。该试验最初是针对以普通波特兰水泥(OPC)为基础的材料而开发的,包括将指示剂溶液喷洒到劈开的试样上,以确定氯离子的渗透深度。新型粘结剂的孔隙溶液成分与基于 OPC 的材料不同,会影响指示剂溶液的反应。为了研究 RCM 试验的适用性,我们测定了由不同类型新型粘结剂制成的砂浆中颜色变化深度中的氯离子含量。结果表明,对于用辅助胶凝材料部分替代 OPC 的粘结剂类型,该测试可提供可靠的结果。而对于不含 OPC 的粘结剂类型,由于引发颜色变化的氯离子浓度不同,迁移系数也存在偏差。

Suitability of rapid chloride migration tests for determining the migration coefficient in mortars made from different novel binder types

The main cause of corrosion of reinforcing steel, especially in infrastructure structures, is the penetration of chlorides, which can lead to high corrosion rates at the reinforcement steel. A frequently used accelerated test method to evaluate the chloride penetration resistance of concrete and mortars is the rapid chloride migration (RCM) test. The test was initially developed for ordinary Portland cement (OPC) based materials and involves spraying an indicator solution onto split test specimens to determine the penetration depth of the chloride ions. The pore solution compositions of new types of binders differ from OPC-based materials, which can affect the reaction of the indicator solution. To investigate the suitability of the RCM test, the chloride content in the depth of the color change was determined in mortars made from different types of novel binders. The results show that the test provides reliable results for the binder types with partial replacement of OPC by supplementary cementitious materials. For binder types without OPC, there is a deviation in the migration coefficient due to a differing chloride concentration that triggers the color change.
