I think it was a few weeks ago that National Geographic was playing at my inlaws.
If i recall correctly the roman concrete that was recreated by the show had to harden in a vat of water after which it was more durable then modern concrete. The blood was spoken about like a mysterious secret ingredient… but that could have been just tv flair. The show after was about aliens.
