What is Steel Fibre Reinforced Concrete?
Steel Fibre Reinforced Concrete is comprised of cements containing fine and course aggregates and Steel Fibre. A superplasticiser is often used to enhance the mix workability. Steel Fibre products are available in a variety of types and sizes. The underlying principle however on all SFRC designs is to provide discontinuous reinforcement and effective crack control. How do Steel Fibres work? Steel Fibres reinforce in three dimensions throughout the entire matrix. They restrain micro-cracking and act as tiny reinforcing bars. The earlier a crack is intercepted and its’ growth inhibited, the less chance it will develop into a major problem. How is concrete improved by using Steel Fibres? Compared to plain or conventional reinforced concrete the most noticeable differences are improved ductility and post crack performance. Shorter fibres with a high fibre count offer superior first crack strength and better fatigue endurance. What concrete properties do Shaktiman® Fibres improve? FLEXURAL
