摘要
本文从混凝土中钢筋的阴极极化、去极化特征以及在氯盐环境中阴极保护对钢筋混凝土握裹力和界面水化产物的影响等方面对钢筋混凝土的阴极保护进行了试验研究。研究查明:阴极保护不影响钢筋与混凝土的握裹力,对水泥的水化无不良影响;同时证实了混凝土保护层质量和系统扩散电阻也是影响钢筋混凝土阴极保护的主要因素之一。
In this paper, we have studied the cathodic polarization and the depolarization character of the steel in concrete, influence of cathodic protection in the chloridc environment on the grip of reinforced concrete and hydrated compound on the interface of the steel and concrete. The result shows that the cathodic protection has no influence over the grip and is not bad for hydrated compound of cement. It also confirms that the concrete cover quality and the system diffuse resister have influence over the cathodic protection of reinforced concrete.
