中文摘要:
      目的 探寻混凝土在杂散电流和氯离子耦合作用下的腐蚀规律,研究新型阻锈剂的阻锈性能。方法 运用电通量法和RCM法,对20 V杂散电流作用下,混凝土的抗氯离子渗透性能进行表征,设置空白组对照实验,对添加阻锈剂后,混凝土的抗氯离子渗透性能进行效果评价。结果 在杂散电流和氯离子的共同作用下,混凝土结构腐蚀的倾向将变大,并且会加速腐蚀反应的进行。混凝土结构在通电48 h后,其电通量高达5778.67 C。与空白组相比,添加阻锈剂混凝土试块的氯离子扩散系数下降45.62%。结论 添加4%阻锈剂的混凝土试块有着较好的抵抗氯离子渗透的能力。
英文摘要:
      The work aims to explore the corrosion regularity of concrete under the coupling action of stray current and chloride ion and study the rust resistance of the new type of rust inhibitor. The penetration resistance of the chloride ion in concrete under the action of 20V stray current was characterized by electric flux method and RCM method, and a comparative experiment was set up to evaluate the effect of the new type of rust inhibitor on the penetration resistance of concrete chloride ion. Under the coupling action of stray current and chloride ion, the corrosion tendency of concrete structure became larger to accelerate the corrosion reaction. After 48 hours of electrification, the measured electric flux of concrete structure reached 5778.67C. Compared with blank group, the chloride diffusion coefficient of concrete blocks with rust inhibitor decreased by 45.62%. The concrete blocks with 4% rust inhibitor have better resistance to chloride ion penetration.
