SPECTER™ Monofilament Fibers are specially designed to minimize early-age cracking in concrete. Millions of high tensile, high modulus filaments in every yard create an extremely dense, three-dimensional network in most cementitious applications. SPECTER™ Monofilament Fibers have the unique ability to reduce explosive spalling and damage in the event of a fire.
- Benefits
- Inhibits and controls the formation of intrinsic cracking in concrete.
- Reduces plastic shrinkage cracking by an average of 75% at a dosage rate of one pound per cubic yard, along with helping to prevent settlement cracking.
- Measurably reduces concrete permeability, thus increasing the durability and service life of the concrete.
- Provides three-dimensional reinforcement against micro-cracking.
- Increases the impact and abrasion resistance of the concrete
Applications & Uses
- Applications
- Recommended for Use in
- Slab-on-ground construction
- Concrete pavement
- Whitetopping and overlays
- Architectural precast
- Shotcrete
- Decorative concrete
- Stucco
- Reducing explosive spalling in the event of a fire
- Marine elements
- Engineering Specifications
SPECTER™ Monofilament Fibers, when used at an appropriate dosage, provide excellent plastic shrinkage and crack reduction for concrete in the plastic state. SPECTER™ Monofilament Fibers are rust proof, alkali resistant, and compliant with industry codes when used in concrete mixed in accordance with ASTM C94/C94M. SPECTER™ Monofilament Fiber should be specified for use in concrete slabs, precast and shotcrete:
- To help control bleed water
- To reduce plastic shrinkage cracking
- To increase abrasion resistance
- To improve impact resistance
- To reduce explosive spalling in case of a fire
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 SPECTER™ Monofilament Fiber is 1.0 lb/yd3 (0.6 kg/m3 ).
- Mixing: SPECTER™ Monofilament Fibers are packaged in preweighed, 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. Standard practices detailed in ACI 302 for placing, finishing and curing concrete should be followed when using SPECTER™ Fibers.

Packaging & Availability
- Packaging Type
- Packaging
SPECTER™ Monofilament Fibers are packaged in pre-weighed degradable 0.5 lb (0.23 kg) to 1.5 lb (0.68 kg) bags that can be added directly to the mixing system.
Storage & Handling
- Storage and Handling
SPECTER™ Monofilament Fibers 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.
