Quick lime as a 'concrete' is nothing new, or newly rediscovered though... The story seems to come up every few years, and anyone that has used a fluidised lime boiler knows how good quick lime is at forming concrete.
And, coincidentally, every time the story comes up there's a company ready to sell you the magic roman concrete.
Yeah, I was thinking it's like the "Voyager Has Left the Solar System" story - we've heard that several times over the years, and probably will again.
To be fair, we keep expanding what we class as the solar system. Poor old voyager keeps getting the goalposts moved!
The year is 76,014. Voyager still hasn't left the solar system. Also, the solar system now contains Proxima Centauri.
What is that, like 12 people now?
