Polyolefin Fiber and Polypropylene Fiber for Concrete Anti-Cracking
Description:
ELITE Reinforcing Macro Synthetic Fiber Twist can be used to instead of steel fiber for reinforcement to cement concrete. Compared with steel fiber, it has the advantage of easy dispersing and blending, no damage to the mixing equipment, etc
Our Fiber have rough surface Treatment by special parallel thread extruding & twisting process. It has high break strength, better dispersion and strong combining ability, will be widely used to instead of steel fibre to reinforce the cement concrete and crack resistant.
1, Our fiber are made by Virgin copolymer;
2, We make the yarn by ourselves. We always have stock and make delivery in 3-7 days;
3, Capacity 600Ton/Month, 7000Ton/Year Production;
4, 70% Export to : Ecuador, Australia, Singapore, Malaysia, Vietnam, Turkey, Iran, France, Sri Lanka, Colombia...

Advantages:
Compared with steel fiber, our fiber Twist has the advantages of corrosion and wear-resistant reducing 50% cost with same volume to steel fiber.
1. Decrease the fragility of high strength concrete;
2. Increase the quality of concrete;
3. Increase the freezing resistance of concrete;
4. Increase the impact resistance of concrete;
5. Increase the durability resistance of cncrete;
6. Increase the fire resistance of concrete.
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).
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.
Applications:
•Slab on Grade and elevated construction (distribution centers, warehouses, etc.)
•Thin walled pre-cast (septic tanks, vaults, walls, etc.)
•Shotcrete for tunnel linings, pool construction and slope stabilization
•Pavements and white-toppings
