Abstract
Alkali-activated concrete (AAC), formulated from industrial by-products such as slag and fly ash, is a sustainable alternative to Portland cement concrete (PCC), yet its brittle nature and limited dynamic performance restrict structural applications. This review explores recent experimental and analytical developments in the fracture mechanics and dynamic response of AAC, emphasizing the role of fiber reinforcement and hybrid binder systems. It synthesizes insights from recent literature (20152025), highlighting key findings on fracture toughness, strain rate sensitivity, fiber-bridging mechanisms, and microstructural behavior. Special focus is given to hybrid AAC mixes and the incorporation of steel and polymeric fibers to enhance energy absorption and crack resistance. This paper also identifies unresolved challenges such as field-scale validation and modeling under multi-axial loading. The findings underscore the transformative role of fiber-hybrid AAC systems in next-generation sustainable construction.
