A). No agglomeration and easily spread around in mortar or concrete. Guarantee crack resistance effectively.
The economic costs of polypropylene monofilament fibers primarily include material purchase, construction/mixing impacts, and long‑term maintenance savings. Key points and typical figures (for reference only—check local market prices):
1. Purchase cost
Price(/kg) | 1.5–6.0 | |
Dosage(kg/m³) | 0.6–2.0 | |
Cost | 0.6kg/m³ | $0.9-$3.6 |
2.0kg/m³ | $1.2-$4.0 | |
2. Other direct or indirect costs/impacts:
You might need to mix longer or tweak the additives, which adds a bit of labor and additive costs.
1. It can reduce plastic cracking and lower maintenance/repair costs; in some jobs, it can partially replace thin steel fibers or allow you to use less rebar/mesh, saving on materials and labor.
2. Better impact resistance and durability can make structures last longer and reduce lifecycle costs.
Normal packing is 0.6 kg, 0.9 kg, or 1.0 kg per film bag; 18 kg/carton; or 20 kg/plastic woven bag. A water-soluble paper bag is available.
1. Q: How to disperse monofilament fibers evenly in a mixer?
A: Add fibers gradually during batching, extend mixing time slightly, and avoid pre-clumping. Use automatic dosing for large-scale
production.
2. Q: How do monofilament PP fibers improve concrete crack resistance?
A: Monofilament fibers bridge microcracks, redistribute stresses, and reduce plastic and drying shrinkage cracks, improving
residual strength and durability.
3. Q: What is monofilament polypropylene fiber used for?
A: Suitable for industrial floors, screeds, precast elements, repair mortars, overlays, and shotcrete where crack control and
durability are needed.
4. Q: How do you guarantee stable quality of micro synthetic fibers?
A: We inspect virgin PP raw materials first, produce with automated spinning lines, conduct standard surface treatment and batch
sampling tests. Every lot of polypropylene monofilament fibers comes with full test reports.
5. Q: What is the standard mixing dosage of polypropylene monofilament fibers?
A: The regular dosage of polypropylene monofilament fibers ranges from 0.6kg/m³ to 1.2kg/m³. Adjust the amount of addition
according to anti-crack requirements and the types of construction materials.
