Ferrock?

Today's fascinating, possible miraculous composite: ferrock.

From CertifiedEnergy...

Ferrock is created from waste steel dust (which would normally be thrown out) and silica from ground up glass, which when poured and upon reaction with carbon dioxide creates iron carbonate which binds carbon dioxide from the atmosphere into the Ferrock.

Roughly 95% of the Ferrock is made from recycled materials, Ferrock is both stronger and more flexible than normal Portland cement, allowing it to be used in highly active environments where there is a consideration for seismic activity.

From ScienceDirect...

At 28 days, the strength of Ferrock concrete exceeds that of conventional concrete by 13.5 percent for compressive strength, 20 percent for split tensile strength, and 18 percent for flexural strength.

From the University of Arizona...

"This all started from an accidental discovery in a lab, which is actually the way it usually goes," [Ferrock inventory David] Stone says. "That was back in 2002, and I included as much as I knew in my doctoral dissertation. But the work goes on. It has taken years to get just a basic understanding of the chemistry involved. But this shouldn’t be surprising, since scientists are still trying to figure out Portland cement and they’ve had 200 years.

"I am into this for the long haul. Time is on our side, since in this era of global warming unsustainable processes like cement manufacture will have to give way to greener alternatives."

As always, I am guardedly hopeful but skeptical until I start seeing Ferrock showing up in buildings.
