摘要
利用电化学综合测试仪,研究了不同水灰比、矿物掺合料、氯离子含量和引入方式以及龄期对钢筋混凝土在除氯前后钢筋自然电位的影响规律。试验结果表明钢筋自然电位随除氯前混凝土水灰比、氯离子含量及养护龄期的增大而增大。
In this study, effects of water cement ratio, mineral admixtures, chloride content and on the spontaneous potential of reinforcement in reinforced concrete before and after electrochemical chloride extraction is investigated utilizing a electrochemical comprehensive determinator. The experimental results show that spontaneous potential of reinforcement increase with the increasing of water cement ratio, chloride content and curing time of concrete before chloride extraction.
