Steel Fiber Concrete Flooring

Steel fiber concrete flooring can provide superior resistance to minimize cracks in hardened concrete, as well as maximum resistance to withstand heavy loads, either dynamic or static. If you decide to use steel fiber concrete flooring, you can select to use a ‘joint-less floor’. Joint-less floors are floors that have minimal joints, providing spaces without joints as large as 40 or 50 meter span wide.

Steel fiber dosage will vary greatly upon the project intended use, and the types of mesh being replaced. Common dosages are in the range between 20-30kg/m3 to 40-50kg/m3 for joint-less floors. Trowelling concrete will help to embed steel fibers into the concrete surface producing a better finish product. Steel fibers will enhance to crack resistance of the concrete, and they can also be used to replace or supplement structural reinforcement. This only can be done through a structural engineer and with proper guidance.

Where to Use Steel Fiber Concrete Floors

Typical applications for steel fiber concrete flooring can be found on parking lots, playgrounds, airport runways, taxiways, maintenance hangars, access roads and workshops. This method is also widely used for port pavements, container storage and handling areas, bulk storage warehouses and military warehouses. Steel fiber reinforced concrete is commonly used in tunnel construction, as it provides additional flexural strength, reduces shrinkage cracking and reduces permeability.

Advantages of Fiber Steel Concrete Flooring

Several advantages can be obtained from this product, for example:

  • Increased load bearing capacity of concrete
  • Reduction of concrete slab thickness
  • Load capacity is not diminished by concrete cracks
  • Increased durability
  • Low maintenance costs
  • Improved flexural properties
  • Reduced absorption of water, chemicals, etc.
  • Can be used on fast track schedule
  • Easier positioning of joints
  • Reduced site labor for managing steel reinforcement
  • Reduced project costs
  • Increased impact and abrasion resistance
  • Even distribution of fibers throughout the concrete
  • Tougher surface with fewer bleed holes
  • Savings will be greater for heavier crack control systems
