Polypropylene Twisted Bundle Fiber Description


Polypropylene twist/bunchy fibre can be used to instead of steel fibre for reinforcement to cement concrete.

Compared with steel fibre, it has the advantage of easy dispersing and blending, no damage to the mixing equipments, etc

The rigid polymer fibre is used polypropylene as its raw material, produced the rough surface Treatment by special parallel thread extruding & twisting process. It has high break strength, better dispersion and strong 

combiningability, will be widely used to instead of steel fibre to reinforce the cement concrete and crack resistant.

Recommend adding quantity: 2.0 – 3.0 kgs fiber to one cubic meter concrete as per different application.

Polypropylene Twisted Bundle Fiber Applying Instruction

1. Ration design of the fibre concrete:
    Generally the recommended amount to add to the concrete is more than 2.7kg per sqm ( volume ratio is 0.3% ), reinforcement      

    adding amount is 5.5kg, Compared with adding 47kg of steel fibre, 5.4kg polymer  fibre has the same volume ratio to  the concrete.

2. length:

     48,50 or 54mm for common crack-resistant requirement.

3. Matching Ratio:

     Usually, it is no need to Change the matching ratio of the concrete.    

     Considering the requirement of fissure-resistant, the polymer fiber

     is recommend to combine with the polypropylene fiber mesh with 

     the volume ratio of 1:1 ( 0.9kg fiber-mesh per sqm of cement  concrete).

4. Mixer Adoption: Double-axle horizontal compelling mixer is priority.

5. Mixing process:

    Crushed stones, fibers and sands are put into the mixer in succession. 

     After stirring for two minutes, fiber will fully spread and then  add cement and water and stir normally. The addition of materials     

     also  can be put into as common concrete, but the stirring time should be properly prolonged to make fiber completely Mixed.

6. Shaping & Maintenance

     There is no special requirement, may along the vibrating time for 30s, The maintenance of the fibre concrete should be  done same         as the normal concrete.

7. Package: 1kg or 0.9kg per bag in common, 10kgs per carton.

     May packed as customers' requirement, Water soluble bag is available also.

Polypropylene Twisted Bundle Fiber Economy

Compared with steel fiber, Polymer fibre has the advantages of corrosion and wear-resistant reducing 50% cost with same volume to steel fibre.
