dustry. Several mechanical properties, such as high strength, durability, and crack resistance, characterize it. UHPC is created by combining cement, fine aggregates, steel fibers, superplasticizers, and other advanced materials, resulting in a concrete that possesses significantly greater resistance capacity as well as durability in comparison to traditional concrete [4; 5; 6; 7; 8]. The utilization of UHPC has demonstrated its ability to enhance structural performance and decrease maintenance demands in contrast to conventional concrete structures. One of the key factors contributing to UHPC's superiority is its exceptional compressive strength. With compressive strength reaching 150-200 MPa or even higher, UHPC allows for the design of thinner and lighter structures while still ensuring high load-bearing capacity. This not only reduces the amount of material used but also decreases the load on the foundation, thereby saving construction costs and increasing economic efficiency. UHPC's crack resistance is significantly improved thanks to the use of steel fibers and superplasticizers. The steel fibers are evenly distributed within the concrete mix, creating a micro-reinforcement network that prevents the development of cracks from the early stages. Superplasticizers not only improve the workability of the concrete mix, making it easier to pour and mold, but also enhance the bond between the components in the concrete, increasing durability and impermeability. Furthermore, UHPC exhibits excellent resistance to harsh environmental impacts, such as corrosion, abrasion, and temperature changes. Advanced components in UHPC, like silica fume and other mineral additives, create a dense microstructure that reduces water permeability and enhances resistance to environmental aggressors. This is particularly important in bridge construction, port facilities, and offshore structures, where materials with high durability and environmental resistance are required. A typical application of UHPC is in bridge construction. Using UHPC in bridge components, such as beams, columns, and bridge decks, not only enhances load-bearing capacity but also extends the bridge's lifespan, reducing maintenance and repair costs. Additionally, UHPC is applied in high-rise buildings, retaining walls, and other structures requiring high durability, opening up new possibilities for the design and construction of modern structures. UHPC represents a breakthrough in concrete technology, offering numerous economic and technical benefits for the construction industry. Researching and widely applying UHPC not only improves the performance and durability of structures but also contributes to promoting sustainable development in construction [7; 8]. One of the most commonly used mineral admixtures for manufacturing UHPC is silica fume (SF). Numerous authors have studied the use of SF and various mineral additives to replace cement in order to enhance the properties of different types of concrete. The Pozzolan materials, such as silica fume and fly ash, are used to improve certain properties of concrete in lightweight concrete mixtures by replacing a portion of the cement weight [9]. Another research study also pointed out that with the use of 30% SF, the fiber can better resist brittleness, thus improving 45% of the bending strength and 55% of the tensile strength, which significantly increases the performance of the UHPC. In practice, the use of 30% SF exhibits an equivalent performance not only under unaged conditions but also under aged conditions, where the bending strength remains around 14.5-15.5 MPa while fracture toughness value fluctuates between 8.0-8.7 kJ/m\({}^{2}\)[10]. The replacement for cement contributes to optimizing the UHPC mixture in compactness and mineral densification. When incorporated into the concrete mixture, SF not only fills the microvoids, increasing the density of the concrete, but also participates in chemical reactions with the hydration products of cement, creating compounds with superior mechanical properties.
