Carbon dioxide mineralization in recycled concrete …
In fact, carbon dioxide mineralization increases the compressive strength of concrete, allowing the reuse of waste concrete in construction applications (rather than in recovery operations, which require lower-quality concrete). Recycling waste concrete could also reduce sand and water required for the production of fresh concrete.

CO2 Mineralization Methods in Cement and Concrete Industry
Production of Portland clinker is inherently associated with CO2 emissions originating from limestone decomposition, the irreplaceable large-scale source of calcium oxide needed. Besides carbon capture and storage, CO2 mineralization is the only lever left to reduce these process emissions. CO2 mineralization is a reversal reaction to clinker …
