Development of Zero-Clinker, Negative-CO2 Concrete from the Atomic Scale

The objective of this fellowship is to train Dr Yunjian Li through the research project titled “Development of Zero-Clinker, Negative-CO2 Concrete from the Atomic Scale (ZeroNegCon)”. This project aims to develop zero-clinker, negative-CO2 concrete for sustainable construction and environmental protection by utilising theoretical design at the atomic scale, nanotechnology, electrolysis and carbon mineralisation technology. In this project, the research will uncover the nanoscale mechanisms of C-S-H formation and carbonation, and CaCO3 crystalline phase transformation, providing theoretical guidance for C-S-H preparation and carbonation, and CaCO3 polymorph control. A zero-clinker cementitious material system will be established with in situ synthesis of C-S-H using ions extracted from natural minerals or industrial byproducts through the electrolysis method. Negative CO2 emission in concrete production will be achieved by applying carbon mineralisation technology to the zero-clinker cementitious materials. The project will also focus on the industry application of zero-clinker, negative-CO2 concrete and evaluate its overall performance. This project seeks to revolutionise the field of construction materials by providing a pathway toward significantly reducing carbon emissions in cementitious binders and concrete. By integrating advanced atomistic modelling techniques, nanoengineering and materials science, this research has the potential to set new standards in sustainable construction, influencing future innovations and policy-making in environmental protection and green building technologies. The success of this project will not only advance scientific understanding but also have a far-reaching impact on global efforts to mitigate climate change.
