A method for producing cement comprises: obtaining a first hydroxide; forming a first carbonate from the first hydroxide; forming a mixture by mixing the first carbonate, magnesium oxide and zeolite; and allowing the mixture to cure to thereby form cement.
C04B 9/20 - Manufacture, e.g. preparing the batches
B01D 53/02 - Separation of gases or vapoursRecovering vapours of volatile solvents from gasesChemical or biological purification of waste gases, e.g. engine exhaust gases, smoke, fumes, flue gases or aerosols by adsorption, e.g. preparative gas chromatography
Magnesium-based cements (in particular, magnesium oxychloride (MOC) cement) are synthesized with a salt (magnesium chloride for MOC cement), water, and magnesium oxide. In this invention the salt is sourced from a waste brine. To the brine is added a base, for example a hydroxide or magnesium oxide. Carbon dioxide is then bubbled through the brine. Calcium carbonate precipitates out of solution. The brine is then left to cure and form cement. Optionally, calcium carbonate precipitate can be added back to (or left in) the brine prior to curing as a filler.
