PLEXUS™ Synthetic Macrofibers are uniquely engineered for shotcrete 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.
FABPRO’s proprietary parallel packaging system aligns all of the fibers in the bag to ensure outstanding fiber distribution in the concrete mix and creates a compact package that results in the lowest possible product freight and storage costs.
PLEXUS™ 54F Synthetic Macrofibers are high tensile fibers manufactured from a blend of 100% virgin polyolefin resins. FABPRO’s PLEXUS™ Macrofibers meet the requirements of ASTM C1116/C1116M “Standard Specification for Fiber-Reinforced Concrete”.
- Eliminates the need for WWF and rebar used as secondary reinforcement in most applications.
- Delivers tight crack control.
- Reduces rebound.
- Reduces construction time, and overall labor and material costs.
- Increases flexural toughness, impact and abrasion resistance.
Features / Properties
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.
Guidelines for Use
The minimum dosage rate for PLEXUS™ Synthetic Macrofibers is 3 lb/yd³ (1.8 kg/m³). PLEXUS™ Fibers can be used at dosage rates from 3 lb/yd³ (1.8 kg/m³) up to 13 lb/yd³ (7.7 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.
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.
PLEXUS™ Fibers are packaged in compact, pre-weighed degradable 5 lb (2.3 kg), 11 lb (5.0 kg) and 15.4 lb (7.0 kg) bags that can be added directly to the mixing system.
