The emerging world of “self-healing” materials
Chief executive Joe Giuliani said the initial applications brought to market would be in self-healing coatings used on marine assets such as ships, docks or oil and gas platforms to protect the metal beneath from corrosion.
Coatings were often damaged by impact when the structures were moved or being installed, or through collision with other bodies in the water.
Giuliani said the technology was based on a system whereby two different microcapsules were incorporated into the coating, one containing the self-healing component and the other containing a catalyst. When the coating was damaged, the microcapsules would rupture and the contents would react with each other, healing the damage to restore the integrity of the coating.
“When damage occurs, they go to the site of the damage and can actually heal underwater without the presence of oxygen,” he said.

Press on, lads. Skynet will be useless without this stuff.

That is nice. Self healing. Any one spot will self heal precisely ONCE, and after that, particularly if it is a frequently damaged location, it will be damaged again and need human repair.
It is good stuff.
engineered cementitious composites have been developed that when stressed, they only create micro cracks, which, if then moistened has enough of the unreacted cement there where it will heal as well.
It bends 300 times more than normal concrete before failure as well.
