MasterFiber 343

Hybrid Synthetic Fibre for Crack Control in the Early and Late Stages of Cast Concrete Applications

How Does MasterFiber 343 Work?

MasterFiber 343 is a blend of engineered synthetic macro and microfibres to control early age and hardened shrinkage cracking. MasterFiber 343 has been developed to provide post-crack flexural strength to enable the replacement and/or supplementation of existing concrete reinforcement products.
MasterFiber 343 conforms to the requirements of EN 14889.2 Class II.

Areas of Application:

MasterFiber 343 applications include, but are not limited to:

• Industrial and warehouse hardstands

• Residential and commercial slabs-on-ground

• Concrete pavements and footpaths

• Architectural precast panels

What Are the Benefits of MasterFiber 343?

• Allows for full or partial substitution of steel mesh reinforcement

• Reduces plastic shrinkage and settlement cracking

• Improves concrete green strength

• Enhances ductility, durability, and post-crack flexural strength

• Decreased construction time and overall reduced labour and material costs

• Provides effective crack control

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