摘要
利用半电池电位(E_(corr))和宏观电池腐蚀电流密度(I_(corr))测量技术,在干湿循环条件下,研究了几种醇胺基阻锈剂对硬化混凝土试块中钢筋的阻锈性能。结果表明,随干湿循环周次的增加,添加阻锈剂的钢筋电极电位呈上升趋势,腐蚀电流逐渐减小,阻锈剂对钢筋具有较好的保护作用,阻锈效果依次为CI-3>CI-5>CI-4>CI-1>CI-2。
Inhibition performance of some amine-alcohol based inhibitors on rebar in concrete under wet-dry cycles corrosion conditions was studied by half cell potential(E_(corr)) and macro-cell current density(I_(corr)) measurements.It was found that E_(corr) increased and I_(corr) decreased gradually with increasing of wet-dry cycles for when inhibitors were added,whereas E_(corr) gradually decreased and I_(corr) increased for the blank rebar specimens.These suggested that the inhibitors studied exhibited good inhibition properties for the rebar imbedded in concrete and the inhibiton effect increased in the order of CI-3>CI-5>CI-4>CI-l>CI-2.
