MasterFiber 143

Polypropylene Fibre for Reinforcing Sprayed and Cast Concrete

How Does MasterFiber 143 Work?

MasterFiber 143 is engineered for use as a secondary reinforcement to control shrinkage, settlement, and temperature cracking both in sprayed and cast-in-situ applications. The inclusion of MasterFiber 143 in a concrete mix will contribute to improving the durability of concrete by increased crack propagation resistance and by its energy absorption characteristics. The fibres will disperse uniformly throughout the concrete mix and act as an anchoring mechanism within the cement matrix, thereby improving the toughness and ductility of the material.

Recommended Uses:

MasterFiber 143 is appropriate for use in ground-supported slabs, industrial flooring, pavement, and precast elements. MasterFiber 143 can also be used in shotcrete applications for increased energy absorption and reduced rebound.

MasterFiber 143 Increases:

• Concrete durability

• Toughness

• Post-residual flexural strength

MasterFiber 143 Decreases:

• Hardened shrinkage

• Shotcrete rebound

• Manual labour

What Are the Unique Features of MasterFiber 143?

MasterFiber 143 can maximise 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 Are the Benefits of MasterFiber 143?

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

• Only minor impact on flow and slump properties of fresh concrete

• High resistance to acid/alkali attack suitable for use in wet underground conditions and subsurface constructions exposed to damp conditions

• Reduces labour, construction, transport, and storage costs compared to a solution with conventional reinforcement
