Steel Fiber Reinforced Concrete (SFRC)

Steel Fiber Reinforced Concrete (SFRC) provides several advantages in terms of structural performance, construction practicality, speed of construction and cost reduction over conventional reinforced concrete.

Structural Advantages
– improves performance of concrete section under direct
tension, flexure, shear and torsion
– increases toughness (ability to absorb energy after cracking)
– increases fatigue endurance and impact resistance
– enhances crack control
– random distribution throughout concrete mix

Performance
– improves ductility of concrete under all modes of loading
– improves fire protection performance of concrete section,
limits spalling
– improves concrete durability

Economic Advantages
– minimizes labor cost , reduces crane hook time
– concrete slab thickness can be reduced
– lowers maintenance cost
– eliminates or reduces cost for reinforcement delivery
– eliminates need for cathodic protection


Construction Advantages
– rapid concreting time
– eliminates need for steel placement, fabrication and handling of reinforcement jigs
Steel fiber is economic and useful construction material that can be used in structural applications alone or with conventional reinforcement.
