Iron-rich alkali-activated materials (Fe-AAM) are considered potential alternatives to ordinary Portland cement (OPC) to limit CO₂ emissions and convert several metallurgical wastes into useful products. Unlike conventional aluminosilicate alkali-activated systems in which the role of the precursor’s main constituents and the reaction products are well defined to some extent, the limited knowledge of the role and state of iron in AAMs restricts its utilisation in the construction sector. Nevertheless, several studies have shown the ability of iron to participate in the formation of alkali-activation reaction products, which induces high compressive strength (over 100 MPa) and provides both environmental and material performance benefits. In this study, we critically evaluate existing data on Fe-rich raw materials, activators, co-binders, mechanical properties, curing types and the reactivity and role of iron in Fe-AAMs.
