In 2015, Dr. David Stone, a former PhD student at the University of Arizona, formulated a way to make a cement substitute using waste steel dust, which becomes hard when it reacts with carbon dioxide and offers greater durability than traditional cement. This invention was known as “Ferrock,” which proved to be a game changer in the field of sustainable building materials. Steel dust waste and silica are its core contents, both of which are byproducts of the steel silicon industry, respectively. Dr. Stone, in collaboration with the University of Arizona, has formed Iron Shell LLC to commercialize his invention. … Continue reading How Ferrock’s 5x Strength Over Concrete is Set to Reshape Sustainable Construction with Steel Dust
