Easy Dispersion Mortar Reinforcement Polypropylene Twist Fiber Product Description
Easy Dispersion Mortar Reinforcement Polypropylene Twist Fiber
1, Polypropylene Twist Fiber Introduction
EltFiber-PPT/B twist/bunchy fibre can beused 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 mixingequipments, etc.
The rigid polymer fibre is usedpolypropylene 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.

Easy Dispersion Mortar Reinforcement Polypropylene Twist Fiber Recommend adding quantity: 2.0 - 3.0 kgs fiber to one cubic meter concrete as per different application.
3. Polypropylene Twist Fiber Function:
A. Decrease the fragility of high strength concrete;
B. Increase the quality of concrete;
C. Increase the freezing resistance of concrete;
D. Increase the impact resistance of concrete;
E. Increase the durability resistance of cncrete;
F. Increase the fire resistance of concrete.
4. Polypropylene Twist Fiber Package: 1000g/pe film bag,10kgs/plastic woven bag,5.5tons/1x20`gp, or 12tons/1x40`HQ.
May packed as customers' requirement, Water soluble bag and Carton is also okay.
5. Polypropylene Twist Fiber Application Field:
A. The surface of road, bridge, runway and floor of the factory.
B. Wall and roof of the tunnel and mine.
C. Dam, river, bridge pier, dock and military protection facilities.
6. Polypropylene Twist 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: 50mm or 54mm for common crack-resistant requirement.
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.
Our Other Mainly concrete fiber :
(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.
