Steel fibers are thin filaments of steel often used for their high tensile and abrasive properties.

Steel fiber reinforced concrete (SFRC) is a type of concrete that includes steel fibers dispersed uniformly throughout the concrete matrix, unlike traditional reinforcement methods such as welded wire reinforcement (WWR) or rebar, which are placed in a single plane. The primary function of the steel fibers in SFRC is to enhance the concrete's structural integrity by controlling micro and macro cracking. This distributed reinforcement helps in modifying the initiation and propagation of cracks, resulting in a more durable and resilient material. While rebar and WWR typically serve to bridge cracks after they have formed, steel fibers work to prevent cracks from becoming significant, thereby providing a more robust and long-lasting solution for various construction applications. Constractive offers expert consultancy on the implementation of SFRC to improve the performance of your engineering projects.
