54mm Polypropylene Hybrid Fiber For Concrete Reinforcement

                     54 mm Polypropylene hybrid fiber for concrete reinforcement

Polypropylene hybrid fiber Description:

Twisted PP fibre and PP fibrillated hybriads is used polypropylene as its raw material, produced the rough surface Treatment by special parallel thread extruding & twisting process.

This fibre can be used as the replacement of steel fibre for reinforcing to cement concrete.

Compared with steel fibre, it has the advantage of easy dispersing and blending, no damage to the mixingequipments, etc.

Polypropylene hybrid fiber Main Technical Specification:

Recommend adding quantity: 2.0 – 3.0 kgs fiber to one cubic meter concrete as per different application.

Polypropylene hybrid fiber Features:

1.High tensile strengh;

2.Increasing the freezing resistance of concrete;

3.Strong elasticity modulus;

4.Increasing the impact resistance of concrete;

5.Good dispeisibility

6.Improving the durability resistance of concrete

7. Fire resistance of concrete.

Polypropylene hybrid 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.

3, Matching Ratio:

Usually, it is no need to Change the matching ratio of the concrete.Considering the requirement of fissure-resistant.
