Steel fiber concrete flooring can provide high resistance to minimize cracks in hardened concrete, as well as maximum resistance to withstand heavy loads, either dynamic or static. Steel fiber dosage will vary greatly upon the project’s 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.
Protech designs & develops blades for cured concrete with steel fiber. Steel fibers can be oriented on the slab in any direction making them a unique design challenge.
Steel fibers enhance the crack resistance of the concrete, and they can also be used to replace or supplement structural reinforcement. It only can be done through a structural engineer and with proper guidance.
Advantages of Steel Fibers in Concrete. Several advantages can be obtained from this product, for example:
- The 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
