The Advantages of SDS-1823 0.18mm-0.23mm Diameter 13±1mm Copper Micro Steel Fiber

  • Good dispersion in concrete;

  • Less impact on UHPC liquidity;

  • Improving the toughness of concrete;

  • The brass fibers provides good impact, fatigue, shrinkage control and ductility in all grade concretes;


  • Dosage: depend on the application and minimum dosage is 120kg/㎥-200kg/㎥

  • Mixing: When pouring sand and aggregates into the hopper, mix an appropriate amount of loose steel fibers evenly, and then add cement. Put it in a mixing table, dry and mix for 2 minutes. If it is glued in rows of steel fibers, you need to add steel fibers after adding water so that the water can dissolve the bonding glue.

  • Put the evenly mixed fiber concrete into the conveyor and transport.

  • Concrete pouring and laying should be compacted.
