‘Burned’ human poop.

They are adding biochar, not fresh, steaming shit.

As a refractory designer, this is something I can really sink my teeth into. Thanks!

Sounds like they’ve discovered an abhorrent secret from the ruins of Poopei.

The beginning of the article mentions the environmental impact of cement manufacture and the importance of replacing it, but later mentions that the research found they can only replace 5-10% of a cement mixture with poop based biochar before it’s strength becomes worse rather than better. Still some difference though I guess.

If we combine all the alternatives that can replace 10% each then we have concrete mix with 0% concrete.
