摘　　要：利用恒电量仪测定了钢筋混凝土中水灰比及二级粉煤灰含量对钢筋 (45 #钢 )的腐蚀行为的影响 ,并用恒电位仪的弱极化动电位扫描曲线解析结果与之比较 .结果表明恒电量仪应用于钢筋混凝土的腐蚀监测简便、快速 .The influences of the ratio of water and ash content and the amount of the second class powered coal ash on the corrosion behavior of the cast iron(45 carbon steel) in the reinforced concrete are studied by using the coulostatic techniques. The results are compared with the dynamic potential scanning results in the weak polarization condition. The results show that the coulostatic method is simple,convenient and speedy to monitor the corrosion of the reinforced concrete.The reinforced concrete with the ratio of water and ash content 0.5 and the amount of the second class powered coal ash no more than 30% has considerable corrosion resistance.
