A carbonatable-based cementitious material may include a carbonatable material comprising magnetite (Fe3O4), hematite (Fe2O3), siderite (FeCO3), geothite (FeO(OH)), ilmenite (FeTiO), limonite (FeO(OH)) nH2O, FeS2 (Pyrite), Obsidian (Volcanic Glass), iron powder, heterosite, bernalite, greenalite, cubanite, annite, electric arc furnace slag (EAF), reducing steel slag, oxidizing steel slag, converter steel slag, basic oxygen furnace slag, ladle slag, slow or fast cooled steel slag, GGBFS, air-cooled slag, copper slag, Solvay slag phosphorous slag, bauxite slag, zinc and lead slag, wollastonite and pseudowollastonite formed through sintering of limestone and sand, or combinations thereof. A carbonatable-based cementitious material may include a reducing agent. A carbonatable-based cementitious material may include an uncarbonatable material comprising sand, gravel, or combinations thereof. A carbonatable-based cementitious material may include one or more admixtures.
A carbonatable-based cementitious material comprising:
A method of carbonating a carbonatable material that comprises iron ore or slag, the method comprising using a reducing agent that comprises carbon or iron to thereby make cementitious binders via formation of FeCO3, CaCO3, MgCO3, or combinations thereof.
A method of preparing a carbonatable-based cementitious material, comprising:
