    STEEL FIBER REINFORCED CONCRETE Nguyen Van CHANH (1) SUMMARY It is now well established that one of the important properties of steel fibre reinforced concrete (SFRC) is its superior resistance to cracking and crack propagation. As a result of this ability to Fibres for Concrete | Maccaferri CorporateWirand® is our steel fibre reinforcement for concrete. It acts directly on the concrete matrix, improving its mechanical properties; ductility, structural strength, toughness and preventing cracking. Steel fibres enable the redistribution of tensile forces, increasing the flexibility of the concrete.
