"Self-Healing Microcapsules as Concrete Aggregates for

Reinforced Concrete (RC) structures are vital to the US's civil infrastructure for their strength and versatility. Unfortunately, RC elements deteriorate rapidly when exposed to corrosive environments. One possible solution is to extend the life of RC elements and systems using microencapsulated corrosion inhibitors to reduce the rebar corrosion rate.
