Recent studies indicate CO₂ curing’s potential to revolutionize concrete production by merging strength gains, durability improvements, and carbon capture sequestration (CCS). Achieving Low-pressure (5–10 psi), shortening the duration of carbonation (to less than 8 hours) has been an attractive improvement for the curing revolution of concrete. These upgrades may significantly reduce chloride penetration in concrete, which makes it a good candidate for severe environments such as marine structures. Studies about accelerated carbonation in precast plain mass concrete indicate that optimizing parameters such as water content, element scale, pressure, and temperature may enhance both mechanical characteristics and CO₂ storage. A novel complex (internal‑external) CO₂ curing method using special types of hydrogels has been reported to yield an 80–100% boost in both strength and durability by enforcing deeper, uniform carbonation into the cementitious matrix. Reviews of all-solid-waste cementitious materials highlight CO₂ mineralization ability (during the curing process) to improve performance. Furthermore, studies on CO₂-reactive calcium silicate cement confirm that ambient pressure CO₂ curing enhances mechanical properties and structural integrity in cement pastes.
Together, these findings reveal that optimized CO₂ curing process can simultaneously sequester carbon, accelerate strength development, and enhance long-term durability. This approach makes the technology a promising strategy for sustainable concrete production.
