    I forget but isn’t it like Roman concrete was super durable or something? Why was that? Does anyone actually know or is it a mystery to this day?

      Don’t forget that there was a slight survivorship bias. You of course can only test the concrete of still standing building and ruins, meaning that the vast majority of buildings that were weaker collapsed centuries ago.
