РЕВОЛЮЦИЯ В СТРОИТЕЛЬНОЙ ОТРАСЛИ - ФИБРОБЕТОН: СВОЙСТВА, РАЗЛИЧНЫЕ ТИПЫ И ПРИМЕНЕНИЕ

Concrete is one of the most widely used construction materials, but it is prone to cracking due to factors like shrinkage, bleeding, and insufficient curing. Fiber-reinforced concrete (FRC) addresses these issues by incorporating fibers such as steel, glass, and polypropylene, enhancing strength, flexibility, and durability. Unlike conventional concrete, which cracks suddenly, FRC distributes stress more effectively, delaying crack formation and improving mechanical resistance. The article states that properties of FRC depend on fiber material, volume, orientation, and stiffness. High-modulus fibers, like steel and carbon, enhance strength, while low-modulus fibers, such as polypropylene, improve impact resistance and crack prevention. However, adding fibers can reduce workability, requiring special admixtures to maintain an optimal mix. The text focuses on FRC that is widely applied in transportation infrastructure, water conservancy, and industrial projects. Steel fiber-reinforced concrete is commonly used in tunnels, bridges, and industrial buildings for its high load-bearing capacity, while glass and polypropylene fibers are utilized in slope stabilization, hydraulic structures, and high-impact environments. Among fiber types, steel fiber-reinforced concrete shows the most significant mechanical improvements, offering better flexural, compressive, and tensile strength, along with enhanced impact resistance and durability. Its reduced corrosion risk and high-energy absorption capacity make it an effective alternative to traditional reinforced concrete. The development of fiber-reinforced concrete marks a significant advancement in modern construction, offering stronger, more resilient, and sustainable structures, with continued research paving the way for further innovations.
