Investigations on microstructural properties of the functionally graded ITZs between different types of modified coral aggregates and cement paste

Key Points

• Microstructural properties vary significantly between different types of modified coral aggregates, enhancing performance.
• Key evidence reveals improved properties in functionally graded interfacial zones with altered aggregates and cement paste.
• Observational analysis explores microstructural characteristics, including bonding quality and transition zones among materials.
• Implications suggest potential advancements in construction materials through optimized coral aggregate use, but further studies are required.
