摘要
本文对砂浆中埋置钢筋的试件进行了快速锈蚀试验研究。根据试验结果 ,环境温度对由于Cl- 引起的钢筋锈蚀的锈蚀率有重要的影响。在 4 0℃以下 ,增加环境温度显著增加锈蚀率 ,在 4 0℃以上增加温度 ,锈蚀率反而下降。
An accelerated corrosion test was carried out on steel reinforcing bars in mortar.According to the results obtained,the ambient temperature has great effect on the corrosion rate under chloride induced corrosion.It has been found that the increase in ambient temperature up to 40℃ accelerates the corrosion rate significantly.The increase over the value of 40℃ has an opposite effect resulting in the corrosion rate slowing down.The possible causes of the effect are analyzed. \[
