Steel Fibre

Crimped Steel Fibre

Crimped Fibers

  • Have a wavy or crimped shape to enhance bonding with the concrete.
  • Offer a balance between cost and performance.
Hooked-end Steel Fibre

Hooked-End Fibers

  • These fibers have hooks at both ends to improve their bonding with the concrete matrix.
  • Commonly used in applications requiring high levels of reinforcement.

Properties, Applications and Advantages

Properties of Steel Fibers

Increased Tensile Strength: Steel fibers add tensile strength to concrete, which inherently has low tensile strength. Helps in reducing the occurrence of cracks.

Enhanced Toughness: Improves the toughness and ductility of concrete. Provides better resistance to impact and dynamic loads.

Crack Control: Distributes stresses more evenly and controls crack propagation. Helps in maintaining structural integrity even after the formation of cracks.

Durability: Improves the durability of concrete by enhancing its resistance to wear, abrasion, and chemical attacks.

Flexural Strength: Enhances the flexural strength, allowing the concrete to withstand bending forces more effectively.


Applications of Steel Fibers

Industrial Floors: strong> Used in industrial flooring to provide high resistance to impact, abrasion, and heavy loads. Ensures longevity and reduces maintenance costs.

Tunnels and Underground Structures: Enhances the structural integrity of tunnels and other underground constructions. Provides better resistance to ground movements and seismic activities.

Bridges and Pavements: Used in bridge decks and pavements to enhance load-carrying capacity and durability. Reduces the occurrence of cracks and spalling.

Precast Concrete Products: Commonly used in precast products like pipes, manholes, and panels to improve their structural performance. Allows for thinner sections without compromising strength.

Shotcrete:strong> Used in shotcrete applications for slope stabilization, lining of tunnels, and repair works. Enhances the adhesion and cohesion of the shotcrete mix.

Hydraulic Structures: Used in dams, reservoirs, and canals to improve durability and reduce maintenance. Provides resistance to erosion and cavitation.

Residential and Commercial Buildings: Employed in the construction of foundations, slabs, and walls to improve load-bearing capacity and durability. Enhances the overall performance of structural elements.


Advantages of Using Steel Fibers

Reduction in Reinforcement Steel: Can reduce or eliminate the need for conventional reinforcement bars in certain applications. Simplifies the construction process and reduces labor costs.

Improved Load-Bearing Capacity: Enhances the load-bearing capacity of concrete structures. Allows for more efficient and economical designs.

Cost-Effectiveness: While the initial cost of steel fibers may be higher, the overall cost is often reduced due to lower labor costs and reduced need for maintenance.

Versatility: Can be used in a wide range of applications and environments. Suitable for both new constructions and repair works.
