- Features
PLEXUS™ Synthetic Macrofibers are uniquely engineered for slab-on-ground and precast applications 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, PLEXUS™ Fibers help to minimize temperature shrinkage cracking, plastic settlement and plastic shrinkage cracking. PLEXUS™ Fibers distribute uniformly throughout the concrete matrix and deliver excellent finish-ability.
- Benefits
- Eliminates the need for WWF and rebar used as secondary reinforcement in most applications.
- Delivers tight crack control.
- Improves green strengths and 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
PLEXUS™ Synthetic Macrofibers, when used at an appropriate dosage, are an excellent 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.
Note: The ASTM C1609 test was run with a dosage rate of 5 lbs/yd³ (2.97 kg/m³) of the PLEXUS™ 44F Fibers, and resulted in an average Re,3 of 25.9% over the 3 panels. The ASTM C1550 test was run with a dosage rate of 10.5 lbs/yd3 (6.23 kg/m3 ) of the PLEXUS™ 54F Fibers, and resulted in an average of 430 joules over the 3 panels.
- Guidelines for Use
- Dosage: The minimum dosage rate for PLEXUS™ Synthetic Macrofibers is 3 lb/yd3 (1.78 kg/m3 ). PLEXUS™ Fibers can be used at dosage rates from 3 lb/yd3 (1.78 kg/m3 ) up to 13 lb/yd3 (7.71 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 (2.37 kg/m3 ) as recommended by the Steel Deck Institute (SDI C-1.0) design code provisions.
- Mixing: PLEXUS™ 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.

Packaging & Availability
- Packaging Type
- Packaging
PLEXUS™ Fibers are packaged in compact, pre-weighed degradable bags weighing from 3 - 15.4 lbs that can be added directly to the mixing system.
Storage & Handling
- Storage and Handling
PLEXUS™ Synthetic Macrofiber should be stored at temperatures below 140°F (60°C). Avoid storing near strong oxidizers and avoid sources of ignition. Use caution when stacking to avoid unstable conditions. Store in a sprinkled warehouse.
