MasterFiber MAC 320

Synthetic Macrofiber

How does MasterFiber MAC 320 work?

​MasterFiber MAC 320 product is a high-performance polyolefin synthetic macrofiber with a twisted shape structure, engineered for use as a secondary reinforcement to control shrinkge and temperature cracking, and settlement cracking. MasterFiber MAC 320 product has been created specifically to replace welded-wire reinforcement (WWR) and reinforcing bars that are typically used as temperature and shrinkage reinforcement.​

Recommended uses

Typical applications include, but are not limited to, the following:

• Hard

  -troweled concrete

• Industrial and warehouse floors

• Residential and commercial slabs-on ground

• Concrete pavements

• Composite metal decks

• Architectural panels

What are the unique features of MasterFiber MAC 320 synthetic macrofiber?

• Uniform distribution throughout the concrete matrix

• Exceptional finishability

• Improves green strengths
  

• Alkali resistant and rust proof

What are the benefits of MasterFiber MAC 320 synthetic macrofiber?

• Eliminates the need for welded-wire reinforcement (WWR) and conventional steel bars used as shrinkage and temperature reinforcement, depending on application

• Effective tight crack control
  

• Reduces carbon footprint compared to convetional steel reinforcement
  

• Increases speed of construction
  

• Improves job site safety
  

• Reduces overall labor and material costs​
  

• Lower paste demand compared to traditional synthetic macrofibers
