| 摘 要： | 针对盐渍土环境下钢筋混凝土阻锈材料,通过对比试验系统分析了无机亚硝酸盐和有机氨基醇两类阻锈剂材料对混凝土抗压强度、模拟液和砂浆中钢筋锈蚀电化学行为的影响,结果表明:相比于无机阻锈剂,有机阻锈剂不仅在模拟液中有效抑制钢筋腐蚀,在干湿交变、高氯盐环境中发生破损时,对钢筋的保护作用更优。

| Abstract: | The reinforced concrete rust-resistant materials in saline soil environment were studied.Through comparative test,the inorganic nitrite and organic amino alcohol inhibitor materials were analyzed for concrete compressive strength and the effect of the electrochemical behavior of steel.The results show that compared with inorganic inhibitor,organic inhibitor not only effectively inhibits corrosion of steel in simulated liquid,but also in wet and dry alternating,high chloride salt environment or when concrete protective layer was damaged,the protection of organic inhibitor on steel bars is better. |
