| 摘 要： | 在对再生混凝土内钢筋腐蚀速率的试验中，采用盐水浸泡以加速钢筋锈蚀，利用电化学线性极化法对普通混凝土与再生混凝土内钢筋腐蚀电流密度进行对比研究．考虑不同水灰比与再生骨料取代率的情况，得出在相同条件下，再生混凝土内钢筋腐蚀速度高于普通混凝土；随着水灰比的减小，再生混凝土内钢筋腐蚀速度减小；随着再生骨料取代率的提高，腐蚀速度加大．

| Abstract: | In the experiment on steel reinforcement corrosion rate in recycled concrete,the method of brine immersion was adopted to accelerate reinforcement corrosion.By the electrochemical linear polarization,this paper carried out a contrast study on the electric current densities of reinforcement corrosion in ordinary concrete and recycled concrete.Taking account of different water-cement ratios and recycled aggregate substitution degrees,the results revealed that the reinforcement corrosion rate in recycled concr... |
