Fire Resistance Durability of Regenerated High Ductility Concrete: An Experimental Study

This paper explores the fire resistance and durability of Regenerated High Ductility Concrete (RHDC), a material designed to enhance both structural flexibility and thermal stability under extreme fire conditions. Due to the increasing demand for safer, more resilient building materials, particularly in high-risk fire zones, the study aims to evaluate RHDC's potential for replacing conventional concrete in critical infrastructure. Experimental procedures involved subjecting RHDC samples to high-temperature fire exposure followed by mechanical testing (compressive strength, tensile strength, and ductility). The results showed that RHDC demonstrated superior fire resistance compared to traditional concrete, maintaining its integrity under prolonged fire exposure. Post-fire mechanical tests revealed that the material retained much of its initial strength and flexibility, making it a promising candidate for fire-resistant construction. This study also discusses the role of regeneration in improving concrete’s fire resistance and highlights its practical applications for modern infrastructure.
