Is this one of those correlation does not equal causation things? Do we know what else if anything might have made for that concrete being good?

There are quite a number of papers on the subject, it appears.

People have, I guess, been researching it for a long time now. In large part because modern concrete is not as long lasting as what the Romans came up with, but the actual Roman Concrete formula got lost over the millennia.

And because the question isn't just how to make it, but why it worked.

The irony is that it may no longer even be possible thanks to all the atomic testing done in the latter half of the 20th century.

That also seems extremely unlikely. Is there any reason to believe extreme isotopic purity is or could be relevant?

There are applications where it matters, but concrete?

EDIT: Additionally, radiological contamination has dropped a lot these days, apparently, because atmospheric atomic testing ended in the early 1960s.
