Plastic Fiber For Cement Curved Macro PP Fiber

Product Details

With polypropylene fiber as its uncooked material, curved pp macro fiber is produced with the aid of special molding manner and surface modification.

It has advantage of acid, alkali resistant, amazing tensile, smooth dispersing, comfort for construction and no harm to vehicles and pavement and no

want for unique conservation.

Curved pp macro fiber may be used in place of metallic fiber to beautify the crack resistance of cement concrete and significantly enhance the durability

and flexural of concrete.

Due to special shape, curved pp macro fiber has proper aggregate with concrete and strong bond.

Applying Instruction

1) Dosage: more than 3kg/cubic meter of concrete.

2) Length: 36mm for general crack level, no more than 25mm for shotcrete, best use no more than 35mm.

3) Mix design:   In general, no need change the ratio parameters of concrete. 

                           Considering the concrete anti-cracking performance requirements, can add 0.9 kg monofilament fiber per square concrete.

4) Mixer : Horizontal Two-shaft forced Mixer.

5) Stirring requirement: 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 can be put into as usual, but the stirring time should be properly prolonged to more than 4 minutes to make fiber completely mixed.

6) Forming conservation: Conservation can be based upon the requirement of ordinary concrete.

   No special requirement, tape time can be extended for 30 seconds according to actual situation. 

   In order not to bring out fiber, plastering should be carried out after the concrete surface passivation slightly.

Feature

Reinforced Functions to Concrete: compared with steel fiber, full-dispersed polypropylene fiber has advantages in its thinness, large amount, non-water absorbency, strong acid & alkali resistance and similar elastic modulus with that of concrete.

The reinforced functions run as follows：

◆Increase seepage resistance

◆Prolong endurance

◆Improve steel protection

◆Increase cracking resistance

◆Increase fire resistance

◆Strengthen spurt & fatigue

◆Improve tensile, bending & folding strength

◆Improve plastic deformity

◆Strong acid & alkali resistance and good endurance

Application

- Projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance.
