Q. Where is fiber-reinforced concrete mostly used in practice? A. Fiber-reinforced concrete (FRC) is extensively applied in various construction scenarios due to its enhanced mechanical and durability properties. A primary area of application is slabs-on-ground, including residential and commercial floors and pavements. The three-dimensional reinforcement provided by fibers significantly improves the crack resistance of these slabs, especially near the surface, ensuring a prolonged service life. For example, as early as the 1980s, many airport pavements and industrial floors in the United States and Europe were constructed with FRC. FRC is also widely used in constructing shotcrete linings for slope stabilization, tunneling, and excavation support due to its enhanced flexural strength, impact resistance, and fatigue performance. Additionally, FRC has been used for bridge deck overlays, floor overlays, and precast units. In specific scenarios, such as raised access floor systems in computer rooms or office automation rooms, carbon FRC has been successfully applied. The versatility of FRC, combined with its unique properties, enables its use in a wide range of structural applications, ensuring both performance and longevity.
