Application of steel fibers as a reinforcing additive to sprayed concrete in tunnels eliminates the need to employ expensive forms and complicated castings which waste valuable time. Using steel fibers reduces micro cracking, accelerates implementation speed and reduces project costs.

Additional applications for steel fibers as a concrete additive:

• Industrial flooring
• Airport and harbor slabs
• Foundation and piles

Polymer Fibers in Concrete

Polypropylene fibers when mixed in concrete will increase permeability during heating thus reducing pore pressure, damage in case of fire and risk of spalling.
