STEEL FIBRE

Steel Fibre

Steel Fibres can be referred to as well-defined, discrete, meagre length strands of steel that gets mixed with fresh concrete very quickly and arbitrarily. These can be portrayed as cold-drawn uni-filament steel strands used for preparing fibre-reinforced concrete (FRC). Steel Fibers are manufactured using the process of deformation by corrugating the cold drawn segments of steel wire. These fibres can be peculiarly designed to be used in concrete products as primary reinforcement material and are also available in collated or loose versions. Steel Fibres are known to possess a higher flexural strength as compared to un-reinforced concrete. These fibres are made up of stainless steel thereby resisting corrosion. The design of Steel Fibres permits for a foreseeable failure factor in their unbending. Thus, they function to reinforce the concrete and hinder micro-cracking, fundamentally behaving as “minuscule reinforcing bars”. Hence, the sooner the crack is obstructed, the minimum the chance of it evolving into a critical flaw. The choice of the type of Steel Fibres relies on the sort of application to be used for.

Steel fibres are generally manufactured with diameters ranging from 0.5mm to 1.0mm, and having length around 25mm to 60mm. However, we are always instrumental in offering customized Steel Fiber having various sizes, diameter and aspect ratio as specified by our esteemed clients. The choice of the type of Steel Fibres relies on the sort of application to be used for. These are generally used as reinforcement material for making shotcrete, pavements, concrete overlays and precast components. Steel Fibres accounts to enjoy numerous properties, such as better crack resistance, higher fatigue endurance features, enhanced fatigue strength, good tensile strength, greater resistance to spalling, durability, good resistance to impact and several other characteristics. Using Steel Fibres serves to deliver noteworthy cost savings, in conjunction with rapid construction, lowered material volume, and minimized labour cost.

We at Precision Drawell are committed to offering excellent technical assistance so that the customers can achieve optimum benefits.

Features of Steel Fibre Reinforced Concrete (SFRC)

  • Flexural Strength: Flexural bending strength can be increased by up to 3 times more compared to conventional concrete.
  • Fatigue Resistance: Almost 1 1/2 times increase in fatigue strength.
  • Heavy Impact Resistance: Greater resistance to damage in case of a huge impact.
  • Permeability: The material is less porous.
  • Abrasion Resistance: More effective composition against abrasion and spalling.
  • Shrinkage: Shrinkage cracks can be eliminated.
  • Corrosion: Corrosion may affect the material but it will be limited in certain areas.

Types of Steel Fibre

  • Hooked End Steel Fibres Loose Type
  • Hooked End Steel Fibres Glued Type
  • Galvanised Hooked End Steel Fibre
  • Stainless Steel Fibres ( Hooked end as well as crimped)
  • Micro Steel Fibre

Toughcrete is cold drawn loose Steel Fibre made using premium quality low content carbon steel for use along with concrete. Toughcrete is discrete (loose) in nature and can be blended with concrete in small quantities. It is evenly scattered within the concrete blend to achieve progressed mechanical properties such as fatigue tolerance, ductility, high flexural strength and impact defiance. Compliant with ASTM A820 standard, Toughcrete proves to be a well-founded and economical solution suitable for low and medium dosages in concrete reinforcement applications. Toughcrete can be manufactured in various forms such as Flat Crimped, Round Crimped and Hooked End.

Application of ToughCrete Steel Fibre

  • Factory & Warehousing flooring
  • Foundation slabs, roads, bridges, and airport runways
  • Mine roof support
  • Manhole covers
  • Slope stabilization
  • Pre cast for tunnel linings
  • Pre cast walls
  • UHPC Concrete

Toughcrete+ is a glued form of Steel Fibres. Glued Steel Fibres are defined as loose hooked finish fibres affixed together to form bundles. These hooked ends grip into the concrete, allowing the stress to be transferred and dispersed evenly and effectively. Toughcrete+ is manufactured by mechanically drawing the low carbon steel wire rods repeatedly until the desired thickness is achieved. The solitary fibres are adhered together with the help of a water-soluble glue, to prevent the bunching of fibres during the process of concrete mixing.

Compliance with ASTM A820 Toughcrete available in 'Hooked end', 'Round crimp' and flat crimped forms and Toughcrete+ available in Hooked end form. It is manufactured in various diameters, lengths, and aspect ratios to suit specific applications in SFRC. No special equipment is required for mixing, placing, or finishing. Toughcrete+ is specially designed to eliminate the balling effect during mixing.

Toughcrete and Toughcrete+ are widely used in cement for shotcreting. It reduces the cost of the work and eases the complexity of the architectural design.
