No towards pig blood and animal fat being a part of the roman concrete which is actually superior to our modern variant.
I considered the blood requirement to be the reason why we aren’t using it now so if we can substitute it by sm else while maintaining most of its strength.
Suffolk pink is TIL for me, thanks. Seems body fluids really where an everyday resource for all kinds of things.
primary thing on the Roman concrete was the addition of ground limestone – any cracks or fractures would be “self-healed” by the limestone
I don’t know of blood or fat being used for the concrete, but for the lime wash – with application of soap, lime wash becomes waterproof, forming tadelakt
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.
