Product Description

Product Description

Polypropylene Fiber

Polypropylene fiber is a synthetic monofilament fiber designed for reinforcing concrete and mortar. It provides excellent dispersion, high tensile strength, and strong alkali resistance, contributing to the long-term durability of cementitious materials. The fiber effectively reduces plastic shrinkage cracking and improves impact resistance. It is widely used in industrial floors, pavements, bridge decks, tunnel linings, and precast concrete elements. Manufactured from virgin polypropylene under strict quality control, it offers a reliable and cost-effective solution for modern construction projects.

FAQ 

Q1: What is PP fiber mainly used for?
A: PP fiber is added to concrete and mortar to control plastic shrinkage cracking, improve impact resistance, and enhance overall durability in applications such as floors, pavements, tunnels, and precast elements.

Q2: How much fiber should be added to the mix?
A: The typical dosage ranges from 0.9 to 1.8 kg per cubic meter of concrete, depending on the specific project requirements and mix design. We recommend conducting trials to determine the optimal rate.

Q3: Does PP fiber affect the workability of concrete?
A: When properly dosed and mixed, PP fiber disperses uniformly and does not significantly reduce workability. It may slightly increase slump loss, but this can be adjusted with water-reducing admixtures if needed.

Q4: Can PP fiber be used together with other additives?

A: Yes, it is compatible with most common concrete admixtures, including plasticizers, superplasticizers, and air-entraining agents. However, we advise pre-testing to ensure compatibility with your specific formulation.

Q5: How is the fiber packaged and stored?
A: The fiber is typically supplied in water-soluble bags or multi-wall paper bags, each weighing 0.9 kg or 1.0 kg for easy dosing. Store in a cool, dry place away from direct sunlight and moisture to maintain product quality.
