<Project Overview>
Concrete is an essential construction material for building structures in both civil engineering and architecture, and as a result, it is produced in large quantities. However, the manufacturing process of cement, the primary material in concrete, emits a significant amount of CO₂. On the other hand, calcium-containing cementitious hydrates, which make up a large portion of hardened cement, have the potential to absorb and fix substantial amounts of CO₂. Therefore, there is a strong expectation for the development of technologies that clarify the CO₂ fixation mechanisms and enhance this function.
This project focuses on the field of cement chemistry, aiming to accelerate carbonation reactions in cement-based materials such as concrete through reaction control. Additionally, it will research and develop innovative and rational methods as well as new materials that effectively utilize all minerals contributing to carbonation. By widely applying these advancements to society, this project seeks to contribute to the realization of a carbon-neutral society.
