Hybrid alkali-activated slag composites incorporating porcelain polishing residue and marble waste with basalt fiber: Mechanical, durability, and microstructural performance

Key Points

• Mechanical properties show significant improvement with the inclusion of basalt fiber, enhancing structural integrity.
• Durability tests reveal that hybrid composites maintain strength under varying environmental conditions, indicating long-lasting potential.
• Assessment using microstructural performance metrics highlights the interfacial bonding between slag and recycled materials for better performance.
• Sustainable options for construction are emphasized, as using waste materials is impactful for reducing environmental strain.
