A method of forming a concrete product includes directly capturing CO.sub.2 from a gas source, the capturing comprising contacting the gas source with an absorption solution having a solvent and a solute, wherein the solvent and/or the solute are capable of reacting with CO.sub.2 to form an anionic compound, adjusting the pH of the absorption solution electrochemically to less than about 7 to release the CO.sub.2 as a concentrated vapor containing CO.sub.2, collecting the concentrated vapor containing CO.sub.2, regenerating the solvent and/or the solute, and optionally collecting the regenerated solvent and/or solute; flowing the concentrated vapor containing CO.sub.2 through a gas processing unit to adjust at least one of a temperature, a relative humidity, or a flow rate of the concentrated vapor containing CO.sub.2; and contacting the concentrated vapor containing CO.sub.2 with a concrete component.
