PP fiber Imitation steel wire

      PP steel-wire-like organic fibers are manufactured by special processing technology. With the special surface configuration and strong combination with the concrete, the fibers can be used to partly take the place of steel fibers in some constructions, and effectively reinforce concrete, improve the impact resistance, fatigue resistance, flexural performance. Compared with the steel fibers, the PP steel-wire-like fibers are alkali and acid-resistant, safe and easy to be used, and can avoid being corroded and rust, in addition, the fibers can reduce rebounding rate in shotcrete and, increase productivity. In some degree, PP steel-wire-like organic fibers have advantage over the steel fibers.

II. Performances of mortar or concrete reinforced by polypropylene fiber

      With the embossing surface, PP steel-wire-like fibers have a strong bond with the concrete so as to increase the cracking resistance and improve the flexural strength.

III. Applications

       The PP steel-wire-like fibers are widely used in concrete and displace the steel fibers in part. The fibers are ideal for applications where a tough，reinforced，corrosion-resistant concrete is required，as in： 
      1.Water conservancy and hydropower constructions;
      2.Port, sea walls and other marine structures;
      3.Highways, driveway, Airport runways, parking lot;
      4.Shotcrete, Tunnel and underground constructions;
      5.Industrial floorings;
      6.Linings and pavements for mines and tunnels.
      The PP steel-wire-like fibers can improve the whole performances of concrete, and can be used in many fields such as industrial floor, marine structures, and some corrosion-resistant structures。Therefore，it has a good economic value.

IV. Standard dosage rate and Mixing process

       4.5Kg per/cubic meter of concrete, the dosage can vary from 2.5-9Kg per/cubic meter of concrete according to actual applications. The mixing process is the same as common cement concrete, there is no special requirements, It is not necessary to change the mix proportion to concrete, But if PP fibers are added after mixing conventional concrete materials, 60 more seconds are required in order to make sure that fibers have a good distribution.

V. Package

      Each package weights 5 Kg. In addition, we can supply proper specs of package according to the customers’ requirements.
