摘要：通过RCM试验、电通量试验和氯离子固化试验，研究了铁尾矿粉和磷渣粉分别单掺和复掺（等质量替代30%水泥）对再生混凝土抗氯离子渗透性能的影响。结果表明：单掺和复掺铁尾矿粉与磷渣粉均能提高再生混凝土的抗氯离子渗透性能，且复掺时铁尾矿粉掺量越大，抗氯离子渗透性能越好；随着铁尾矿粉掺量的增加，再生混凝土的氯离子结合能力提高；在氯离子浓度较低的环境下，再生混凝土中的氯离子主要以物理吸附和化学结合两种形式存在；在氯离子浓度较高的环境下，再生混凝土中的氯离子主要以化学结合形式存在，物理吸附作用相对较弱。 Abstract: Through RCM test, electric flux test and chloride ion curing test, the influence of iron tailings powder and phosphorus slag powder (replacing 30% cement) on the chloride ion penetration resistance of recycled concrete was studied. The results show that the chloride ion penetration resistance of concrete can be improved by adding iron tailings powder and phosphorus slag powder. When mixed, the greater the content of iron tailings powder, the better the chloride ion penetration resistance. With the increase of the content of iron tailings powder, the chloride binding capacity of recycled concrete increases. In the environment with low chloride ion concentration, chloride ions in recycled concrete mainly exist in the form of physical adsorption and chemical binding. In the environment with high chloride ion concentration, the chloride ions in recycled concrete mainly exist in the form of chemical binding, and the physical adsorption is relatively weak.
