Effect of in situ CO mixing of cement paste on the leachability of hexavalent chromium (Cr(VI)).

In situ CO mixing technology is a potential technology for permanently sequestering CO during concrete manufacturing processes. Although it has been approved as a promising carbon capture and utilisation (CCU) method, its effect on the leachability of heavy metals from cementitious compounds has not yet been studied. This study focuses on the effect of in situ CO mixing of cement paste on the leaching of hexavalent chromium (Cr(VI)).
