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
