Fibers in Concrete

Fibers in concrete are small, hair-like materials—such as steel, glass, or synthetic fibers—added during mixing to improve its properties. They help control cracking caused by shrinkage or temperature changes, increase toughness, and enhance durability. When the concrete is under stress or begins to crack, the fibers act like tiny reinforcements that hold it together, preventing cracks from spreading and improving its overall strength and lifespan. This makes fiber-reinforced concrete especially useful in slabs, pavements, and structures subject to dynamic loads or harsh conditions.
