PP Fiber for Concrete
Fibers for concrete reinforcement are generally referred to as synthetic fibers. They’re crucial components for reinforcing concrete.
Yuanwang has an independent fiber factory in China. We specialize in the production of various construction fibers.
Polypropylene fiber is the most popular type. Length options include 3mm, 6mm, 9mm, and other custom lengths. PP fiber is also called anti-crack fiber, synthetic fiber, or plastic fiber. They are made entirely from polypropylene material, which is safe to use.
Polypropylene fiber for concrete enhances strength and prevents cracks. It makes the concrete mixture tougher and more durable.
✅ Makes concrete stronger.
✅ Prevents crack formation.
✅ Increases durability of structures.
✅ Extends the lifespan of concrete.
✅ Easy to mix into concrete.
✅ Suitable for various construction projects.
Polypropylene Fiber Concrete for Better Performance
Polypropylene fiber reduces cracking in concrete by enhancing its resistance to shrinkage and settlement. It improves the durability and flexural strength of concrete.

3 Things to Check When Choosing PP Fibers for Concrete
PP Fibers' Technical Data Sheet (TDS)Always check the TDS of the PP fiber for concrete.
This ensures that the fibers you purchase meet the required tensile strength and elongation at break of the concrete.
PP Fibers DispersionFibers with good dispersion will completely separate into single strands and spread randomly in three dimensions in the concrete mixer.
Fibers with poor dispersion will form clumps, leading compressive strength decrease of the concrete.
The Feeding ConvenienceSome manufacturers produce fiber products in water-soluble paper bags, such as WOTAIchem.
They can be directly put into the mixer along with the paper bag, and the paper bag will dissolve quickly.
This is a way to achieve precise mixing ratio. Besides, it is also environmentally friendly.

FAQs
Have any questions? We are always here to help you.
1. Choose the right fiber
Polypropylene fibers come in various forms, including macro synthetic fibers, staple fibers, and monofilament fibers, each with unique advantages.
If your main goal is to enhance crack resistance, Yuanwang™ recommends using short fibers with a length of 12-19mm.
For higher impermeability, choose fine-diameter monofilament fibers, as their smooth surface and high aspect ratio help fill concrete pores, reduce water penetration, and extend concrete lifespan.
In general:
Staple fibers (6–19mm) are primarily used for crack prevention.
Macro fibers (>50mm) are suitable for structural reinforcement in concrete.
2. Control the dosage
The typical dosage of polypropylene fiber ranges from 0.6–1.2 kg/m³ (approximately 0.05%–0.1% by volume). The exact amount should be determined through testing:
Pavements & thin-walled structures: 0.6–0.9 kg/m³
Hydraulic structures & mass concrete: 0.9–1.2 kg/m³
Shotcrete: 3–9 kg/m³
The optimal dosage depends on factors such as fiber type, length, and construction environment. Excessive fiber content may reduce workability, requiring adjustments to admixtures (e.g., naphthalene superplasticizer).
-PP fibers are known for their high tensile strength, flexibility, and chemical resistance.
-PVA fibers have high tensile strength, excellent adhesion, and resistance to alkalis.
-PET fibers offer high tensile strength, resistance to stretching, and durability.
-PAN fibers provide exceptional tensile strength and stiffness.
Different fiber products have different effects on the concrete mix.
-PP fibers control cracks and boost impact resistance in concrete.
-PVA fibers make concrete stronger, tougher, and more durable.
-PET fibers improve concrete’s performance after cracking and make structures more durable.
-PAN fibers toughen concrete, resist impacts, and control cracks.
These fibers reinforce concrete but vary in material and performance, suited for different uses and concrete needs.
