MasterFiber 151 SPA - Polypropylene fiber for reinforcement in sprayed concrete and cast concrete applications as alternative and/or supplement to existing concrete reinforcement products
What is MasterFiber 151 SPA?
MasterFiber 151 SPA is a fiber extruded from
polypropylene polymers and formed into a flat fiber
that can be used in concrete mixes for both spray
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 151 SPA 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
What is MasterFiber 151 SPA used for?
Recommended for use in:
- Wet shotcrete applications in tunneling or
- Any subsurface construction
- Any structure where impact toughness shall be
What are the benefits of MasterFiber 151 SPA?
- 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
- High resistance to acid/alkalis attack suitable for
use in wet underground conditions and
subsurface constructions exposed to damp
- Reduces construction time compared to a
solution with conventional reinforcement
