Abstract

Provided herein are active flow-through carbonation curing systems useful for contacting carbon dioxide (CO₂) gas streams with concrete materials under ambient pressure. This contacting causes a carbonation reaction in which CO₂ forms materials, such as, but not limited to, calcium carbonate (CaCO₃). The methods include, but are not limited to, contacting a conditioned flue gas containing CO₂ inside of a carbonation chamber with green bodies or concrete components in which flue gas properties such as temperature, relative humidity, flow rate, and flow direction, are self-adjusted during the curing process based on a self-sensing instrumentation system inside a curing chamber and carbonation kinetic regression model. This system improves CO₂ capture efficiency and material performance while reducing processing energy.
