1, Description:
ELT-TWIST This newer class of fibers has emerged over the last 15 years as a suitable alternative to steel fibers when dosed properly.
Typical materials include polypropylene and other polymer blends with the same physical characteristics (e.g., length, shape) as steel fibers.
These fibers can be dosed from 3 to 20 lbs/yd (1.8 to 12 kg/m3).
ELT-TWIST is a 100% virgin blended copolymer synthetic Structural macro-fiber successfully used as an alternate to steel fibers, welded wire mesh
and conventional reinforcing bars in a wide variety of secondary reinforcement applications.
Benefits and characteristics
- It has the common advantages of steel fiber and synthetic fiber.
- Excellent dispersion
- It is suitable for both dry spray and wet spray process.
- Improving toughness and durability of concrete
- Improve the strength of concrete and prevent rebound
- Alkali and acid resistance, no rust, not easy to corrosion
- Lower dosage and lower use cost
- The surface does not need to be trimmed, and the operation is safe and easy.
