Last I heard concrete was recycled by simply using the rubble as stones to throw into new concrete. Usually sorted by size to adhere to certain regulations or something but never without new concrete. Can you give me a source for anything else?

How is that not recycling?
The issue is that you still need lots of new concrete this way. You don’t end up with a circle of your resources.
It’s not a bad idea but it isn’t climate neutral unless you come up with a climate neutral way to mix new concrete.
