MasterFiber 142 - Macro polypropylene fiber for reinforcement in sprayed and cast concrete applications as alternative and/or supplement to existing concrete reinforcement
What is MasterFiber 142?
MasterFiber 142 is a fiber extruded from
polypropylene complying to EN 14889-2 Class II
and ASTM C1116 / C1116M. It is formed into an
embossed fiber that can be used in concrete mixes
for both sprayed and cast in-situ applications. The
inclusion of fibers in a concrete mix will contribute
to improving the durability of concrete by increased
crack propagation resistance and by its energy
absorption characteristics. The fibers will disperse
uniformly throughout the concrete mix and
effectively act as an anchoring mechanism within
the cement matrix thereby improving the toughness
and ductility of the material.
MasterFiber 142 can maximize concrete service
life by providing superior resistance to attack from
damaging environmental elements such as water,
chlorides, and corrosive environments such as
sewerage conduits and/or saline water.
What is MasterFiber 142 used for?
Recommended for use in:
- Wet shotcrete applications in tunneling or mining applications
- Any subsurface construction
- Any structure where impact toughness shall be increased
What are the benefits of MasterFiber 142?
- Easy to dose either at the batch plant or on site concrete mixer truck prior to application
- Only minor impact on flow & slump properties of fresh concrete
- High resistance to acid/alkalis attack suitable for use in wet underground conditions and subsurface constructions exposed to damp conditions
- Reduces construction time compared to a
solution with conventional reinforcement
