摘　　要：迁移型阻锈剂是抑制混凝土中钢筋腐蚀的材料之一,但对于致密的混凝土,其迁移能力有限。采用电化学方法在含C1-的混凝土模拟孔隙液中筛选3种迁移性有机阻锈剂,研究在自然和电场条件下阻锈剂在钢筋混凝土试件中的渗透和对钢筋的阻锈能力。试验结果表明,BE对钢筋的阻锈效果优于市售同类国外产品,其对钢筋的阴极和阳极电化学过程均有抑制作用,是一种混合型阻锈剂;电场作用能加速BE在混凝土中的渗透,提高阻锈效果。The application of migrating corrosion inhibitors （MCI） reinforced steel in concrete structures, but the migrating ability is limited for of 3 kinds of migrating organic corrosion inhibitor （MCI） was investigated concrete solutions with C1 through is one of many methods of protecting dense concrete. The inhibition behavior for reinforced steel rebar in simulated polarization curve and polarization resistance measurements. The permeability of BE in concrete specimen and its effect of inhibiting rebar corrosion were also investigated. The results show that BE is a mixed inhibitor, with inhibiting anodic and cathodic process of rebar simultaneously, and has better inhibiting effect for rebar than two marketable MCI＇s from abroad. Electric field can accelerate BE to permeate into concrete, and thus it has better inhibiting effect for rebar.
