Abstract: This study aims to comprehensively compare the mechanical properties, durability, and sustainability of Ultra-High Performance Concrete (UHPC) with traditional concrete, highlighting the advancements and potential applications of UHPC in modern construction. By employing a rigorous experimental framework, we systematically evaluated the compressive strength, tensile strength, and durability under various environmental conditions including freeze-thaw cycles and permeability tests for both concrete types. UHPC demonstrated significantly enhanced performance characteristics with compressive strengths exceeding 150 MPa, compared to 40 MPa for traditional concrete. Tensile strength measurements also showed a marked improvement with UHPC achieving up to 10 MPa, a substantial increase from the 2.5 MPa recorded for traditional concrete. Durability tests indicated superior resistance to environmental stressors, with UHPC showing minimal degradation in harsh conditions, while traditional concrete displayed notable susceptibility to damage. The sustainability analysis focused on the lifecycle impacts of both materials, considering the energy consumption, carbon footprint, and potential for incorporating recycled materials in the mix. The findings suggest that while UHPC initially presents a higher environmental cost due to its intensive production process, its longevity and reduced maintenance requirements could offset this impact over time. This comparative study underscores the superior mechanical and durability properties of UHPC, advocating its use in scenarios where longevity and minimal maintenance are critical. However, the higher initial costs and environmental impact require careful consideration, suggesting a targeted application in high-value infrastructure projects. Future research should explore cost-effective and environmentally friendly alternatives for UHPC components to enhance its accessibility and sustainability.
