Abstract: A manufacturing process of a concrete product includes: (1) extracting calcium from solids as portlandite; (2) forming a cementitious slurry including the portlandite; (3) shaping the cementitious slurry into a structural component; and (4) exposing the structural component to carbon dioxide sourced from a flue gas stream, thereby forming the concrete product.

Abstract: Methods and formulations for use of phase change materials (PCMs) as coatings or integrated with building materials are disclosed. A formulation comprises an amount of phase change material, for example a mass fraction of about 0.01 to about 0.50. The PCM materials may be applied as a surface treatment such as paint, for example in order to provide improved thermal regulation to a building or a portion thereof.

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.

Abstract: Some embodiments of the invention include a method of producing iron carbonate binder compositions including providing a plurality of binder precursors including a powdered iron or steel, a first powdered additive comprising silica, a second powdered additive including calcium carbonate, and a powdered clay. The method includes mixing the plurality of binder precursors and a water additive to form an uncured product, and feeding at least a portion of the uncured product into a curing chamber. The curing chamber is fluidly coupled to a CO2 source so that some CO2 from the CO2 source reacts with the uncured product to form a cured iron carbonate containing product and at least one reaction byproduct, where at least some byproduct can be fed from the curing chamber to the CO2 source for use as a fuel by the CO2 source.

Abstract: A manufacturing process of a “low cement content” concrete includes: (1) forming a cementitious mixture by combining a cement, a carbonate source, and an aluminous source; and (2) curing the cementitious mixture to form the concrete. The carbonate source is included in an amount greater than 20% by weight of solids combined in the cementitious mixture.

Abstract: Provided herein are compositions comprising concrete and one or more phase change materials (PCMs) for prevention or reduction of thermal damage in a cementitious system, and uses thereof.
