The 'living concrete' that can heal itself - CNN.com

The bioconcrete is mixed just like regular concrete, but with an extra ingredient -- the "healing agent." It remains intact during mixing, only dissolving and becoming active if the concrete cracks and water gets in.

wow....cool

Crushed live coral was used for road surfacing in some of the Caribbean and Lesser Antilles islands. They kept it wet with sea water for a few days and it grew together as smooth and hard as concrete.

Good luck with getting away with that today.

Given the rate of natural coral growth . . . it may as well have been crushed giant sequoia trees.

That is cool and creative. I wonder how they keep the capsules from dissolving when they are mixing the concrete, since they are released by water.

Interesting to read, thanks for link.
