If what scientists are finding out about ancient Roman concrete can help them to determine the exact ingredients to use, as well as the best mixing, and curing process, to use, we just might have a new concrete that won't require specialized sand.
And in case you haven't been paying attention, that specialized sand is in very short supply right now. So short in fact that many places around the world are being threatened ecologically because resource thieves are sucking it up in secret as fast as they can (sand also makes a far too convenient way to expand territory and so it has more than one big, potential, consumer).
This development will certainly bear watching.
Ancient Romans made world’s ‘most durable’ concrete. We might use it to stop rising seas.
