【摘要】 采用动电位极化曲线和电化学阻抗谱研究了D-葡萄糖酸钠在模拟混凝土孔隙液中对钢筋的保护作用。结果表明,D-葡萄糖酸钠的加入导致混凝土钢筋的腐蚀电位负移,对钢筋的阴极电化学过程有抑制作用。D-葡萄糖酸钠能够阻挡侵蚀性离子对钢筋表面的侵蚀,其缓蚀效果随浓度增加而增加。更多还原

【Abstract】 The inhibition effects of sodium D- gluconate on reinforcing steel corrosion was investigated by electrochemical polarization curves and electrochemical impedance spectroscopy in simulated pore solution.The anodic reaction of steel electrode was suppressed.It can suppress the electrochemical reaction by forming a deposition film in the steel/concrete interface,which can retard the attack by aggressive Cl~- ions.更多还原
