The steel fibers are manufactured specifically for concrete reinforcement by deformation process
in corrugating cold drawn steel wire segments. The material is in accordance with ASTM A820, Type I, low carbon, cold drawn, deformed steel wire. In
addition, the fibers geometry provides increased mechanical anchorage. The addition of these fibers improves many engineering properties of the concrete. These enhancements include modifications to the macro/micro cracking
mechanism, impact resistance, fatigue strength and flexural strength. The degree of enhancement is dependent on the dosage level. With fiber contents of 1.5 percent to 2.0 percent by volume, direct tensile strength will increase 30 to 40
percent, and flexural strength (first crack) will increase 50 to 150 percent. T add, the random orientation of the fiber reinforce the concrete in all directions.

Applications of steel fibers
Fiber reinforcement can be primary or secondary reinforcement in a wide rangef of construction projects such as
Highways and roadways
Shotcrete in minning/tunneling
Explosive and impact resistance structures
Industrial Floorings
Toppings for decking systems
Mine support blocks
Concrete flatwork such as slabs and pavements
Precast elements
Spillways and taxiways
Seismic resistant structures (Dam constructions)
Refractory shotcrete and castables
Effects of Fiber Reinforcement
Resistance to crack propagation due to plastic and drying shrinkage
Resistance to
thermal and moisture stresses
Increased ductility
Increased impact and abrasion resistance
Increased tensile, flexural and fatigue strength
Decreased permeability
Decreased
mix-water bleed rate
Decreased handing damage during transport of dry-cst products to curing areas
Packaging
Packed
as 20 kgs - non-woven HDPE sacks.
Safety
The use of gloves and eye
protection during handling of fibers i strongly advised
The results achieved using Steel Fibers are better than conventional reinforcing practices. High impact and fatigue resistance conbined with reduced time to prepare site reduced cost makes the use steel fiber reinforcing the preferred choice.
