We talk with Dr. David Stone, inventor of Ferrock – Carbon Negative Building Material. David as a doctoral candidate, at the Arizona State University, researched on how to prevent iron from rusting. It is especially challenging where iron exposed to humidity and oxygen in our atmosphere returns to its natural state – rust. During experimenting with silica as a rust-inhibitor, he saw the silica and rust reacting and bubbling. When cooled this compound became a very hard substance and David realized it could be a used as a substitute for cement. David disclosed his invention and has received a patent. What had caused this chemical reaction? What had caused this chemical reaction? Learn more on this episode.
