SPECTER™ Monofilament Fibers are manufactured from 100% virgin, homopolymer polypropylene resin and meet the requirements of ASTM C1116/C1116M “Standard Specification for Fiber-Reinforced Concrete”, ASTM D7508/D7508M “Standard Specification for Polyolefin Chopped Strands for use in Concrete” and the requirements of ICC ES AC32 Sections 3.1.1 for plastic shrinkage reinforcement.
Features / Properties
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
The recommended dosage for the SPECTER™ Monofilament Fiber is 1.0 lb/yd3 (0.60 kg/m3).
SPECTER™ Monofilament 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. Standard practices detailed in ACI 302 for placing, finishing and curing concrete should be followed when using SPECTER™ Fibers.
SPECTER™ Monofilament Fibers are packaged in pre-weighed degradable 0.50 lb (0.23 kg) to 1.5 lb (0.68 kg) bags that can be added directly to the mixing system.
