Title: Low Carbon Cement-Based Materials: From Mineral Dissolution to Properties Optimization
Cement and concrete, as the most widely used man-made materials, are significant contributors to global CO2 emissions. To address this challenge, diverse strategies have been developed, including reducing cement clinker usage, enhancing concrete's mechanical properties and durability, and integrating carbon capture, utilization, and storage (CCUS) technologies. At the core of these strategies lies cement hydration—a complex process governed by simultaneous mineral dissolution and hydration product precipitation.
This talk will introduce the application of Digital Holographic Microscopy to observe the in-situ dissolution of cement clinker minerals at the nanoscale, offering new insights into this fundamental process. Building on these findings, we will explore advanced techniques for optimizing concrete properties. Highlights include enhancing concrete toughness through innovations in Calcium Silicate Hydrate structures and pioneering the development of electrochemical energy storage concrete. Together, these advancements aim to pave the way for next-generation low-carbon cement-based materials.
