| Primary Audience | Industry/Business |
| Results and Impact | The keynote 'Decarbonising large infrastructure projects: the case of the HS2 in the United Kingdom' was presented in the Symposium 'Low carbon cements' as part of the Spanish Congress of Materials, Malaga, Spain, 24th-28th June, 2024. This presentation showcased the outcomes of ongoing collaborative projects between SCS Railways, ARUP and my team to realise the widespread uptake of calcined clays in the United Kingdom. This presentation was very well received by cement producers in Spain, and I received very positive comments as this is a great example of collaboration between industry and academia to deliver tangible outputs for the benefit of industry and society. We received an invitation for submitting a feature article in the magazine 'Cemento y Hormigon', distributed among all cement and concrete producers in Spanich speaking countries, which is currently in preparation. |

| Form Of Engagement Activity | Participation in an activity, workshop or similar |
| Part Of Official Scheme? | No |
| Geographic Reach | International |
| Primary Audience | Postgraduate students |
| Results and Impact | The talk 'Advances in characterising carbonation in low clinker and alternative cements' was presented at The 3?? International Workshop on Technologies for low carbon and lean construction, Chennai, India, 28-31 Jan 2024, where participant from different countries shared the latest research on sustainable construction materials and practices. This presentation attracted significant interest as there is ongoing debates about identifying the trade offs when using novel cementitious materials for decarbonising concrete, their CO2 uptake capacity (so they can ack as carbon sinks during service) and the ability of these novel cements to withstand the environmental service conditions, without losing their design properties. |
