Abstract

Infrastructure maintenance costs billions of dollars every year. The corrosion of steel reinforcement is one of the primary causes of the deterioration of concrete infrastructure. The standard protection for steel reinforcement is epoxy coating, but it becomes ineffective when damaged. An improvement to this system incorporates self-healing agents into the epoxy coating, automatically repairing damage and extending the life of the structure. This paper presents the results of experimentation conducted with the self-healing agent tung oil microencapsulated in a polymer shell and added to a two-part epoxy. Accelerated corrosion testing showed that the experimental coatings with microcapsules exhibited significantly longer lifespans than samples with unmodified epoxy coatings.
