SikaFiber®-142

(former MFiber 142)

POLYPROPYLENE MACRO FIBRES FOR CONCRETE AND SHOTCRETE

SikaFiber®-142 is a fiber extruded from polypropylene. 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.
SikaFiber®-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.

  • Easy to dose either at the batch plant or on site concrete mixer truck prior to application
  • 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
