Ultra-high-performance concrete (UHPC) is a critical material in modern infrastructure, known for its exceptional compressive strength (exceeding 150 MPa), superior durability, and unique material composition. UHPC typically consists of fine aggregates, mineral admixtures such as silica fume, and a high cement content. However, compressive strength alone does not ensure high performance or sustainability. To improve its mechanical behavior, the incorporation of fibers into the UHPC matrix is essential. This study investigates the influence of triple fiber reinforcement, micro steel fibers, carbon fibers, and polypropylene (PP) fibers on the mechanical and fresh properties of UHPC. Carbon fibers, known for their high strength-to-weight ratio, chemical inertness, excellent tensile strength, and high elastic modulus, offer a promising alternative to conventional steel fibers in enhancing the performance of UHPC. The primary objective of this research is to analyze the synergistic effects of combining steel, carbon, and PP fibers to enhance flexural strength and overall toughness. Although the inclusion of fibers slightly reduces the compressive strength of UHPC, the results demonstrate that PP fibers effectively mitigate the risk of spalling. Moreover, the combination of fibers significantly enhances the electrical conductivity of UHPC, with carbon fibers playing a dominant role due to their higher conductivity compared to steel fibers. Microstructural analysis using scanning electron microscopy (SEM) reveals a uniform distribution of fibers throughout the UHPC matrix. Additionally, the observations confirm both pullout and fracture mechanisms in carbon and steel fibers, contributing to improved toughness and energy absorption capacity of the composite.
