3D shape reconstruction and generation of natural pozzolan particles

Natural pozzolans are widely used in the construction industry due to their beneficial properties, including enhanced durability, increased long-term concrete strength, and contributions to sustainability by reducing Portland cement usage and carbon emissions. Additionally, they play a role in producing lunar regolith simulants due to their geochemical similarity to lunar regolith. While their physical and chemical characteristics are wellstudied, the impact of particle morphology is significant. Understanding pozzolan particle shape and surface characteristics can optimize their reactivity, workability, and effectiveness in construction materials. Despite its importance, particle morphology is not widely assessed due to the fine scale of the particles. This paper presents a systematic approach to reconstruct and generate realistic pozzolan particles, offering valuable insights into their morphology and enhancing practical applications. Our proposed method, with its potential to improve numerical studies and serve as a foundation for pozzolan-related applications, holds promise for future construction materials and space applications.
