MasterFiber MAC 100

Synthetic macrofiber

How does MasterFiber MAC 100 work?

MasterFiber MAC 100 product, a synthetic macrofiber, is manufactured from a proprietary blend of polypropylene resins, in compliance with ASTM C 1116/C 1116M. MasterFiber MAC 100 product is specifically engineered for use as shrinkage and temperature (secondary) reinforcement and provides excellent plastic shrinkage control and reduced settlement cracking.

Recommended uses:

• Industrial and warehouse floors
• Commercial slab construction
• Concrete pavement
• White topping and overlays
• Thin wall precast concrete
• Shotcrete
• Composite metal decks

What are the unique features of MasterFiber MAC 100?

• Tensile strength of 60,000 psi (415 MPa)
• Meets the requirements of ASTM C 1116/C 1116M “Standard Specification for Fiber-Reinforced Concrete”
• Uniform distribution throughout the concrete mixture
• Excellent finishability
• Excellent post-first crack performance

What are the benefits of MasterFiber MAC 100?

• Eliminates the need for welded-wire reinforcement (WWR) and small diameter bars used as secondary reinforcement, depending on the application
• Effective tight crack control
• Provides excellent plastic shrinkage crack reduction and settlement control
• Improves green strengths – permits earlier stripping of forms with less rejection
• Reduces construction time and overall labor and material costs
• Increases flexural toughness, impact and shatter resistance?
