Abstract: Decarbonization of the cement and concrete industry is critical to China’s carbon peaking and neutrality goals. As an important approach to mitigating the greenhouse gas emissions associated with cement and concrete production, CO2 mineralization has aroused the interest of academia and the industry worldwide. This report overviews recent advances in CO2 mineralization techniques for use in building materials production, and presents our research progress on carbon-negative building materials production that uses advanced CO2 mineralization techniques and 100% industrial residues as raw materials. The mineralization reaction mechanism of alkaline industrial residues as a function of their chemical/mineralogical compositions will be highlighted. Application of the CO2 mineralization technique at the industrial scale will also be demonstrated.

Thanks to Prof. Zhengwu JIANG for the wonderful Seminar!
