摘　　要：采用磨细矿渣和粉煤灰等活性掺合料,对地铁混凝土抗杂散电流性能进行对比试验研究,结果表明,掺加活性掺合料使混凝土钢筋钝化膜电阻Rc和累积电量得到提高,从而使地铁混凝土的抗杂散电流能力显著增强。By adopting grinding slay and fly ash,etc.active aggregate and taking comparative experiment research on the resistng stray electric courrent performance of the subway concrete,the result showed that the active aggreagate can make the concrete reinforcement resistance of passivating coat Rc and accumulated electric consumption improving,so it can remarkably strengthen the ability of resisting stray electric current performance of the subway concrete.
