Polypropylene fiber consists of 99.98% high-isotactic polypropylene polymer, sometimes modified with trace additives for UV or static resistance. 2. How do you specify PP fiber dimensions for concrete? Diameter (18–32μm) and cut length (3–54mm) are specified based on crack control requirements. For typical slab and shotcrete, 18μm × 19mm or 32μm × 38mm are common. 3. What are the industry test standards for polypropylene fibre ? Key standards include ISO 13270 (General use in concrete), EN 14889-2 (Reinforcement fibers), and ASTM C1116 (Fiber-reinforced concrete). 4. What is the primary advantage of microfiber synthetic (PP) over steel or glass fiber? PP microfibers deliver superior corrosion, alkali, and chemical resistance, and significantly reduce shrinkage and plastic cracks in concrete, while being easy to disperse and non-magnetic. 5. Can polypropylene fiber be added directly to onsite concrete mixing? Yes. It disperses rapidly in dry and wet mixes. Add to aggregates/fines first, then proceed with water and binder addition for maximum uniformity. 6. What is the service life of PP fiber concrete in harsh environments? Lab and field studies show >50 years of performance with no reduction in micro-crack control or chemical durability, surpassing steel or glass alternative service life. 7. Are there color-custom fibers for architectural applications? Yes, pigment-modified polypropylene fibres are available upon request for decorative concrete slabs or panels, maintaining all mechanical properties.
