Abstract

A major source of deterioration in infrastructure is the corrosion of steel reinforcement. Epoxy coatings offer protection to steel reinforcement, but when damaged, become ineffective. A previous project developed a self-healing epoxy coating using microcapsules containing tung oil. The coatings were applied to steel rebar that was embedded in concrete and subjected to accelerated corrosion testing. The self-healing epoxy lasted at least 300% longer than a control coating. No differences between damaged and undamaged experimental samples were shown. This report explores the results of testing using controlled damaging methods to create differences in the performance of epoxy coatings. The project resulted in a new protocol for consistent and sufficient damage to epoxy coatings.
