Yep, it’s the the lime. And:
“ The team is now working on commercializing their concrete as a more environmentally friendly alternative to current concretes.”
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.
that’d be great, a lot of buildings are torn down just because the concrete cracks.
i’d be interested in seeing how using better concrete impacts overall costs and of course emissions. because the building ends up standing for a lot longer, the temperature isolation becomes very sub-par over time. that would increase total energy consumption compared to buildings that are frequently rebuilt.

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?

but very promising.
