In his keynote “State of the Geopolymer R&D 2023”, Professor Joseph Davidovits provides a comprehensive review of the advancements in geopolymer science and applications over the past year. He begins with discussing ongoing research into the fundamental geopolymerization process and new discoveries around acid-based geopolymerization. Moving into practical applications, Prof. Davidovits examines the development of super high strength metakaolins and how geopolymers can help mitigate global warming through their lower carbon footprint compared to Ordinary Portland Cement. Other timely topics covered include the role of geopolymers in sustainable water resources management and repairing critical infrastructure like roads and pavements damaged by floods. The keynote also talked about progress with 3D printing using geopolymer binders to create strong and stable ceramic-like materials. A highlight is providing details on the world’s first 3D printed house in geopolymer concrete. Lastly, Prof. Davidovits envisions future opportunities for geopolymers to enable more durable habitats for permanent settlements on the moon.
