摘　　要：借助模拟混凝土孔隙液及实验室混凝土环境对研制的复合型钢筋阻锈剂阻锈性能及渗透性能进行研究。通过盐水浸渍试验、干湿冷热试验、极化试验评价了研制钢筋阻锈剂的阻锈效果;同时在对已有渗透性能评价方法总结的基础上,对涂有钢筋阻锈剂试块的氨氮离子浓度进行分析,从而得出本文的测定方法可以测定钢筋阻锈剂在混凝土中的渗透深度,且简单可行。The antirust performance and permeability of composite rust inhibitor are researched at the concrete pore solution and laboratory environment.The antirust effect of rust inhibitor is evaluated by immersing in salt test,thermocycling test and polarization test.The ammonia and nitrogen ion concentration of samples covered with rust inhibitor are analyzed based on some permeability evaluation methods.The penetration depth of rust inhibitor in concrete is ascertained by the mentioned method.The result shows that the method is easy and feasible.
