Key test for re-healable concrete (concrete that patches itself)

Experimental concrete that patches up cracks by itself is to undergo outdoor testing.

The new material could potentially increase the service life of the concrete - with considerable cost savings as a result.

The work is taking place at Delft Technical University, the Netherlands.

Not to worry, the concrete is gonna be closely monitored to see how it behaves...

Interesting stuff! Is this part of the mixture joining the blocks in the pyramids?

Thanks for this very interesting article. It is a wonderful idea. I hope they can get it to a place where it can be used commercially.
