What is Twisted Bundle PP Fiber?

Twisted Bundle PP Fiber (also called “bundled PP macro fiber”) is produced by precision drawing and surface treatment so that each bundle separates rapidly during mixing and forms a dense 3D reinforcement network. Compared with plain monofilament, the twisted bundle delivers faster opening, stronger mechanical anchorage and higher efficiency at the same dosage. It is chemically inert, non-corrosive, lightweight, and causes zero wear to mixers and pumps.

ECOCRETE™ Twisted Bundle PP Fiber is engineered from premium polypropylene and processed to open quickly in mixing, dispersing into thousands of micro-filaments that bridge micro-cracks and toughen the matrix. It improves crack control, anti-seepage, impact resistance and durability across floors, roads, tunnels and water structures.

Key Benefits of Twisted Bundle PP Fiber

  1. Crack Control: Bridges micro-cracks during plastic and drying shrinkage; reduces crack width and density.
  2. Anti-Seepage & Durability: Lowers connected porosity for better water-tightness, freeze–thaw and chloride resistance.
  3. Toughness & Impact: Increases post-crack load capacity, flexural strength, impact and fatigue resistance.
  4. Chemical & Corrosion Proof: Non-rusting, non-conductive, excellent resistance to salts, alkali and acids.
  5. Easy Mixing: Rapid opening from bundle to filaments; uniform dispersion; no balling; no equipment abrasion.
  6. Cost-Efficient Alternative: Reduces risk of surface cracking and maintenance; can replace part of secondary steel mesh in many applications.

Applications of Twisted Bundle PP Fiber

  1. Industrial Floors & Pavements: warehouses, logistics hubs, cold rooms, sports courts
  2. Roads & Bridges: pavements, parapets, barriers, overlays
  3. Shotcrete: tunnels, mines, slope stabilization, culverts
  4. Water & Municipal Works: dams, tanks, canals, water-retaining and anti-seepage structures
  5. Precast Elements: pipes, panels, manholes, modular components
  6. Marine & Chemical Environments: coastal works, chemical plants, corrosion-prone areas

How to Use & Recommended Dosage

  • Typical Dosage (general crack control): 1.0–1.5 kg/m³
  • Enhanced Toughness / Shotcrete: 3.0–6.0 kg/m³
  • Hybrid Recommendation: For surface crack control on slabs, combine Twisted Bundle PP Fiber 1.0 kg/m³ with PP Mesh/Monofilament 0.4–0.6 kg/m³ for optimized micro- and macro-crack bridging.
  • Mixing Procedure: Add aggregates → add Twisted Bundle PP Fiber → add cement → add water/admixtures → mix until full dispersion; adjust water or admixture for target workability.
  • Compatibility: Works with standard ready-mix, pumping and shotcreting equipment; compatible with common admixtures.
