PP Twist Fiber

Short Description:

● GRECHO PP Monofilament Fiber is a kind of high strength bunched monofilaments fiber made by special technology with PP as the main raw material.
● In concrete or mortar to add GRECHO PP mono-filament fiber, can effectively prevent temperature changes, plastic and dry shrinkage caused by micro cracks, so as to prevent and control the occurrence and development of cracks, effectively improve the concrete crack resistance, permeability resistance, and impact resistance performance.

Increases overall durability, fatigue resistance and flexural toughness

Easily added to concrete mixture at any time prior to placement

Provides three-dimensional reinforcement against macro-cracking

Apply Instruction

1. Ration design of the fiber concrete : Generally the recommended amount to add to the concrete is more than 2.7kg per m3(volume ratio is 0.3%), reinforcement adding amount is 5.5kg, Compared with adding 47kg of steel fibre, 5.4kg polymer fiber has the same volume ratio to the concrete.

2. Length : 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 PP fiber mesh form with the volume ratio of 1:1 (0.9kg fiber-mesh to per m3 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 fiber concrete should be done same as the normal concrete.

DEMAND FOR SUSTAINABLESOLUTIONS

Economy

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

Advantages

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

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
