In traditional construction, once concrete cracks, its structural integrity is considered compromised unless heavy steel rebar is there to hold it together. However, by mixing small metallic fibers (up to 60 mm long) directly into the concrete, the material gains a property called flexural toughness or ductility.

Engineers rely on BS EN 14651 to verify that a specific steel fiber reinforced concrete (SFRC) mix meets the requirements of Eurocode 2. Unlike traditional rebar, which is calculated based on area and yield strength, SFRC performance is defined by its "toughness" or energy absorption.
