Abstract
A method of diffusing CO2 within a concrete mixture that includes mixing a non-recycled aggregate material with a CO2 gas in a pretreatment chamber of a concrete preparation system to form a CO2 adsorbed aggregate material, transferring the CO2 adsorbed aggregate material from the pretreatment chamber into a cement mixing chamber of the concrete preparation system, and mixing the CO2 adsorbed aggregate material with cement and water to form the concrete mixture, where mixing the CO2 adsorbed aggregate material with cement and water releases CO2 from the CO2 adsorbed aggregate material and diffuses CO2 into the concrete mixture to form a carbonated concrete mixture.
