MasterFiber MAC 244 | Synthetic Macrofiber

How does MasterFiber MAC 244 synthetic fibers work?

MasterFiber MAC 244 product, a synthetic macrofiber, is manufactured from a proprietary blend of polypropylene resins, in compliance with ASTM D7508/D7508M “Standard Specification for Polyolefin Chopped Strands for Use in Concrete”. MasterFiber MAC 244 product can be used in producing Type III Synthetic Fiber-Reinforced Concrete meeting the requirements of ASTM C1116/C1116M “Standard Specification for Fiber-Reinforced Concrete”. MasterFiber MAC 244 product also meets the requirements of CSA B66-10 “Design, material, and manufacturing requirements for prefabricated septic tanks and sewage holding tanks.”

Recommended concrete applications:

• Industrial and warehouse floors

• Pavements

• Residential and commercial slabs-on-ground

• Mass concrete

• Thin walled-precast

• Whitetopping/Overlays

What are the unique features of MasterFiber MAC 244?

MasterFiber MAC 244 product is engineered for use as secondary reinforcement to control shrinkage and temperature cracking, and settlement cracking. MasterFiber MAC 244 product was created specifically to replace welded-wire reinforcement (WWR) and reinforcing bars that are typically used as temperature and shrinkage reinforcement.

MasterFiber MAC 244 product has the following features:

• Uniform distribution throughout the concrete matrix

• Excellent flexural performance

• Excellent finishability

• Improved green strengths

• Alkali resistant and rust proof

What are the benefits of MasterFiber MAC 244?

• Eliminates the need for welded-wire reinforcement and reinforcing bars used as secondary reinforcement, depending on the application

• Effective tight crack control

• Provides excellent control of settlement cracking

• Permits earlier stripping of forms with less rejection

• Reduces construction time and overall labor and material costs

• Reduces the effects of handling and transportation stresses

• Increases flexural toughness, impact and shatter resistance
