twist hybrid pp polypropylene Fiber macrofiber 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.
twist hybrid pp polypropylene Fiber Description:
twist hybrid pp polypropylene Fiber can be used to instead of steel fibre for reinforcement to cement concrete.
Compared with steel fiber, it has the advantage of easy dispersing and blending,
no damage to the mixing equipments,etc.
twist hybrid pp polypropylene Fiber 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 combining ability, will be widely used to instead of steel fibre to reinforce the cement concrete and crack resistant.
twist hybrid pp polypropylene 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 fiber,
5.4kg polymer fibre has the same volume ratio to the concrete.
38mm, 48mm 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.
Compared with steel fiber, twist hybrid pp polypropylene Fiber has the advantages of corrosion
and wear-resistant reducing 50% cost with same volume to steel fiber.

Recommend adding quantity: 2.0 – 3.0 kgs fiber to one cubic meter concrete as per different application.
twist hybrid pp polypropylene Fiber Function:
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.
1. The surface of road, bridge, runway and floor of the factory.
2. Wall and roof of the tunnel and mine.
3. Dam, river, bridge pier, dock and military protection facilities.
