MasterFiber™ MAC200F  

MasterFiber MAC200F synthetic macro reinforcing fiber is manufactured from a proprietary blend of polypropylene resins, in compliance with ASTM C1116/C 1116M, “Standard Specification for Fiber- Reinforced Concrete.” MasterFiber MAC200F is specifically engineered for use as secondary reinforcement and provides excellent plastic shrinkage control and reduced settlement cracking. MasterFiber MAC200F provides increased flexural toughness and increased impact, shatter and abrasion resistance, improving the concrete’s longterm durability and integrity. MasterFiber MAC200F is a true replacement for welded wire reinforcement, conventional light gauge steel reinforcement and steel fiber. It is specifically designed for use in shotcrete applications and slab-on-grade.

Features

• Excellent post-first crack performance
• Excellent finishability
• Optimal passage through grates and pumps due to its helical shape and structural
• integrity

Benefits

• Eliminates the need for welded wire reinforcement (WWR) and conventional steel bars as secondary reinforcement, depending on the application
• Effective tight crack control
• Provides excellent plastic shrinkage crack reduction and settlement control
• Reduces production time and overall labor and material costs
• Improves green strengths – permits earlier stripping of forms with less rejection
• Reduces handling and transportation stresses
