| 摘 要： | 对杂散电流影响下海砂混凝土的力学性能以及钢筋锈蚀特征进行了研究。结果表明:随着加载电压的增大以及通电时间的延长,其抗压强度和弹性模量明显下降;通过电化学当量和钢筋腐蚀电流密度特征变化,杂散电流对河砂混凝土钢筋锈蚀影响较弱,但会加速海砂混凝土钢筋锈蚀,产生不利影响。

| Abstract: | The corrosion characteristics of steel bars and the mechanical properties of sea sand concrete under the influence of stray current are studied.The results shows that with the increase of loading voltage and the extension of energization time,the compressive strength and elastic modulus decrease obviously.The change of electrochemical equivalent and corrosion current density reviews that the influence of stray current on the corrosion of river sand concrete reinforcement is weak,but it will accelerate the corrosion of sea sand concrete reinforcement,which has an adverse impact. |
