Abstract: Some embodiments of the invention include cementitious iron carbonate binder precursor compositions that includes powdered iron or steel, a first powdered additive including silica, a second powdered additive including calcium carbonate, at least one powdered clay, and a fibrous and/or woven additive. In some embodiments of the invention, the precursor composition includes an alumina additive. In some further embodiments, the powdered clay includes kaolinite clay and/or metakaolin clay. In some further embodiments, the precursor composition includes an organic reducing agent such as oxalic acid. Some embodiments include up to about 60% by weight of powdered iron or steel, up to about 20% by weight of the first powdered additive, up to about 8% by weight of the second powdered additive, up to about 10% by weight of at least one powdered clay, and up to about 2% by weight of an organic acid.
