let me guess, the didn't fill it with iron that would corrode and expand and blow out the concrete? or the fact that it has an excess of fired lime that re-seals cracks?
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.
What is that, like 12 people now?
