Abstract
Cathodic Protection has been introduced as a method of protecting metals under the ground or sea from corrosion. Since 1970, it has been applied to reinforced concrete structures as a corrosion protection method. After 1990, it became used around the world, and its usability has been well confirmed. But this method has some problems in terms of construction and economy. To solve these problems, a Cathodic Protection Method using a highly-durable metal spray was developed. First, the specimen was covered with anodic materials (Zn, Al) by using metal spray. The corrosion protection performance was confirmed by measuring the corrosion current of the specimen. Through the experiment, it is possible to confirm that the Cathodic Protection Method using a high metal spray provides effective protection against corrosion to reinforced concrete structures.
