The pivotal role of steel fibers in bridge construction cannot be overlooked. Their tensile strength must undergo rigorous verification to ensure it is not less than 380 MPa, thereby guaranteeing their significant role in bridge construction.

Bridge-specific steel fiber is a special type of steel fiber primarily used for enhancing bridge structures. It possesses high strength, stiffness, durability, and fatigue resistance, along with excellent plasticity, forgeability, and weldability. Steel fiber is a recyclable, cost-effective, and environmentally friendly engineering material, widely utilized in various fields such as industry, construction, transportation, agriculture, water conservancy, energy, defense, aerospace, and more.

Steel fiber is a type of material with novel functions and high performance. When planning the proportion of steel fibers, although the basic method is similar to that of ordinary concrete, there are significant differences. Specifically, steel fibers are used to control standard strengths, including compressive strength and flexural strength. The content of steel fibers is determined based on the required flexural-tensile strength in the design. In addition, the adaptation of water and sand ratio to fiber content needs to be considered per unit. Adding an appropriate amount of 0.5% (volume fraction) steel fibers, while increasing the water consumption per unit by 6 kilograms and the sand ratio by 2%, ensures optimal performance.

Currently, steel fibers have been widely applied in the field of bridge construction and can be said to be an indispensable part of it. Special steel fibers for bridges exhibit excellent durability, significantly extending the service life of bridges. It is anticipated that in the coming years, the application areas of special steel fibers for bridges will further expand, and they will achieve even better development.
