复合氨基醇类钢筋阻锈剂阻锈效果及对混凝土性能影响研究

Anti-corrosion Effects of Corrosion Inhibitor Admixtures Containing the Complexing Amino Alcohols and Influence Researches on Concrete Performances

采用动电位扫描和失重法评价了亚钙和复合氨基醇类钢筋阻锈剂的阻锈效果,并比较其对混凝土性能的影响。研究表明,复合氨基醇类阻锈剂阻锈效果优于亚钙,能改善混凝土工作性能和抗氯离子渗透性能、降低混凝土早期温升,早期抗压强度略有降低但后期强度基本无不利影响。

The anti-corrosion effects of corrosion inhibitor admixtures containing the calcium nitrite or complexing amino alcohols were evaluating with potentiodynamic scanning and weightlessness method, and their influences on the properties of concrete were also compared. Researches show that, the anti-corrosion effects of corrosion inhibitor admixture containing complexing amino alcohols, which can improve the workability, and enhance resistance to the penetration of chloride ions,and decrease the concrete temperature rise at early age,are better than that of calcium nitrite. The corrosion inhibitor admixture with complexing amino alcohol just results in compressive strength of concrete at early age declining slightly,and does not have any influences on compressive strength of concrete at long age yet.
