Self-healing “living” concrete

living_concreteImagine building or managing a new building or community and never having to worry again about its concrete cracking, concrete warranty issues or concrete maintenance?  Now try to imagine that the concrete is alive and it heals itself.  No, this is not science fiction.  It’s hard to fathom but such a concrete product now exists.  The limestone in concrete, a natural additive, becomes activated when rained upon and thereupon the bacteria in the concrete heals itself.  Its commercial application could be 2 to 3 years away.
