PP Polypropylene Twisted Hybrid Fiber for Concrete Floor Airport Runway Reinforced
1, Description:
ELT-TWIST Macrosynthetic Fiber Reinforcement for Concrete Advantage,Macrosynthetic Fiber is a blend of polypropylene and polyethylene resins,
was produced by our patent advanced technology for fiber spinning,Twist bundle,modified by adding functional additive and special surface-treating.
Macrosynthetic Fiber is used to replace steel fibers, welded wire mesh (WWM), rebar and conventional reinforcement in concrete.
ELT-Twist is actually a Hybrid of two fibers:A standard fibrillated polypropylene fiber to reduce and control shrinkage and temperature cracking.
A twisted-bundle monofilament fiber made of a strong synthetic copolymer, to increase load-transfer and post-crack performance
2,Advantage:
- improve the crack resistance of concrete.
- Improve the impermeability of concrete.
- Improve the wear resistance of concrete.
- The impact resistance and fatigue resistance of concrete are improved.
- The bending and bending resistance of concrete are improved. 6, Improve the reinforcement capacity of concrete.
- The plastic deformation ability of concrete, especially high strength concrete, is improved.
- It is acid and alkaline resistant and has good durability.

5, Packing:
6, 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, 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).
3, Mixer Adoption: Double-axle horizontal compelling mixer is priority.
4, 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.
5, 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 Application:
- Field Concrete and Industrial Floors
- Coastal Structures & Ports
- Mining
- Tunnel Applications
- Residential Buildings
- Parking Lot Flooring
- Pre-cast and Prefabricated Structures
- Water Structures
- Concrete Pavements
