This shouldn't be too shocking... the concrete we use today is only 1 ingredient different from what the Romans used.
> Not shocking. It is an ancient substance, and I think only recently explained. Unless I have recovered memory syndrome, I saw an article a number of years ago with a modern explanation of how it works.-I remember about twenty years ago some guy touting an environmental technology, and he had mentioned that his technology was similar to that used by the ancient Egyptians to build the pyramids. Seemed pretty wild speculation back then. -Having said that I could never really believe the huge blocks being hauled into place. Bags of sand etc and vessels of water - now we are talking.-So you may well have recovered memory syndrome, but then again perhaps not.
