ACI 440 (American Concrete Institute 440)

ACI 440 is a set of guidelines from the American Concrete Institute that focuses on the design, use, and maintenance of fiber-reinforced concrete. This type of concrete contains small fibers, like steel, glass, or synthetic materials, added to improve its strength, durability, and crack resistance. The standard provides technical requirements for selecting, testing, and applying fiber-reinforced concrete in various construction projects, ensuring safety, performance, and longevity. It helps engineers and builders make informed decisions about incorporating fiber reinforcement into concrete structures for better results.
