High Quality Rigid Polymer Fiber

Product Description:

Instructions of High Quality Rigid Polymer Fiber:

The High Quality Rigid Polymer Fiber uses polypropylene as its raw material. It is a substitute for steel fiber in the reinforcement of cement concrete and crack resistant. Compared with steel fiber, it has the advantage of easy dispersing and blending, no damage to the mixing equipments, high break strength, strong bondability, etc.

Technical Data of High Quality Rigid Polymer Fiber:

Equivalent Dia(mm): Ø 0.3±0.05

Strand Length(mm): 20,30,54

Density(g/cm 3 ): 0.91

Elastic Modulus (MPa): >3500

Shape: bundle-like and twisted

Tensile strength(%): 8-15

Break Strength(MPa): ≥ 350

Resistance to acid,alkali: strong

Features of High Quality Rigid Polymer Fiber:

1. Ration design of the fiber concrete

The recommended volume for concrete is more than 2.7kg /m 3 ( volume ratio is 0.3% ) , reinforcement adding amount is 5.5kg , Compared with adding 47kg of steel fiber, 5.4kg polymer fiber has the same volume ratio to the concrete.

2. length

50mm 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 to 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 disperse and then add cement, water and stir normally. The addition materials also can be put into as common concrete, but the stirring time should be properly prolonged to make fiber completed mixed.
