- Features
PERFORMAX™ HT Synthetic High Tensile Macro Fibers are uniquely engineered with higher tensile strength to provide better “Built-In Reinforcement” as a replacement for steel fibers, welded-wire fabric (WWF) and conventional reinforcing bars in a variety of secondary reinforcement applications. In addition, PERFORMAX™ HT Synthetic High Tensile Macro Fibers help to minimize temperature shrinkage cracking, plastic settlement and plastic shrinkage cracking. Other features include:
- Improved worksite safety by eliminating handling of WWF and light rebar
- Uniform distribution of fibers throughout the concrete matrix
- Excellent finish-ability
- Superb post-first crack performance
- Benefits
- Eliminates the need for WWF and conventional steel bars as a secondary form of reinforcement. Does not replace primary/structural reinforcement.
- Delivers 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 abrasion resistance.

- Engineering Specifications
PERFORMAX™ HT Synthetic Macro Fiber, when used at an appropriate dosage, is an option for the replacement of WWF and rebar as a safe and easy-to-use reinforcing system. The fiber is rust proof, alkali resistant, and compliant with industry codes when used in concrete mixed in accordance with ASTM C94/C94M. PERFORMAX™ HT Synthetic Macro Fiber should be specified for use in concrete slabs:
- To enhance residual strength, toughness and durability
- To reduce plastic shrinkage cracking
- To increase abrasion resistance
- To improve impact resistance
- To reduce permeability
FABPRO POLYMERS does not recommend this fiber for use in slabs as a substitute for primary/structural reinforcement.
- Guidelines for Use
- Dosage: The recommended dosage for the PERFORMAX™ HT Synthetic Macro Fibers is 3 lb/yd3 (1.8 kg/m3 ). It can be used at dosage rates from 3 lb/yd3 (1.8 kg/m3 ) up to 13 lb/yd3 (7.8 kg/m3 ) or the equivalent dosage of 0.2% to 0.9% by volume, unless otherwise specified. For composite metal deck applications, minimum dosage is 4 lb/yd3 (2.4 kg/m3 ) as recommended by the Steel Deck Institute (SDI C-1.0) design code provisions.
- Mixing: PERFORMAX™ HT Synthetic Macro Fibers are packaged in pre-weighed, ready-to-use, degradable bags which are designed to be introduced at any time before or during mixing of concrete produced in accordance with procedures specified in ASTM C94/C94M.
