I found this article interesting so I thought I would share.

Interesting, one of the reasons it worked is that there was no reinforcing steel in the concrete for the saltwater to react with. saltwater does nasty things to reinforcing steel.
It would be interesting to see tests on a similar modern material.
Well they say that the volcanic rock seawater combined created Crystals that grow within the concrete filling space that would otherwise open and crack.

Cool. science is so cool. I enjoyed it as a kid in school.
I have been watching “graphene” for a bit too. Impressive material.

kind of a self healing concrete, I have read about that recently

That’s pretty cool. science has gone a long way.
I am curious how long it will take for the bacteria to fill the cracks etc."If you're going to do something, do it right the first time"

Palm Springs, CANice article! It’s amazing how they built stuff to withstand the test of time!
Lime is commonly used and is considered self healing opposed to portland cement.
