Anti-corrosion effect of a new-type of organic inhibitor and its influence on concrete property

通过电化学阻抗谱对一种新型有机阻锈剂的阻锈效果进行试验研究。研究阻锈剂对新拌混凝土性能、硬化混凝土强度及收缩性能以及水泥水化热的影响。研究结果表明:该有机阻锈剂可以对钢筋起到良好的保护作用,防止氯盐对钢筋的不利影响,对混凝土的收缩具有一定的抑制作用,并能略降低水泥水化热。有机阻锈剂的使用可以避免传统的亚硝酸盐类阻锈剂对环境造成的污染,是一种环境友好材料。

Experimental study on the anti-corrosion effect of a new-type of organic inhibitor is implemented by electrochemical impedance spectroscopy（EIS） in this paper.The influence of the inhibitor on properties of fresh concrete,compressive strength and shrinkage property of hardened concrete and the hydration heat of cement are studied.The results indicate that the organic inhibitor can protect steel bar effectively from the adverse effect of chloride,restrain the shrinkage of concrete and reduce the hydration heat a little.Compared with traditional nitrite inhibitor,the organic inhibitor is helpful to avoid the environmental pollution and is a kind of environment-friendly material.
