FABPRO POLYMERS’ SPECTER™ HP Synthetic Micro Fiber is a “Best-in-Class” new generation of polypropylene microfiber for concrete reinforcement. FABPRO’S unique technology combines ultra-thin diameter with high strength, resulting in the highest level of plastic shrinkage crack prevention available. Over one hundred million high tensile and high modulus filaments per yard of SPECTER™ HP create an extremely dense, three dimensional network in any cementitious application.
SPECTER™ HP’s superior ability to reduce early age cracking is accomplished at an engineered dosage rate of only 0.5 lb/yd3 (0.3 kg/m3 ) of fibers. Independent test results have consistently confirmed that only 0.5 lb (0.23 kg) of SPECTER™ HP consistently produces superior PSCR results compared to other monofilament fibers at a typical 1.0 lb/yd3 (0.6 kg/m3) dosage rate – providing better performance at a significantly reduced in-place cost.
- Benefits
- Inhibits and controls the formation of intrinsic cracking in concrete.
- Reduces plastic shrinkage cracking by an average of 90% at a dosage rate of 0.5 lb/yd3 (0.6 kg/m3) with over 110 million fibers.
- 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.
- Performs as an excellent companion in blends with macro synthetic fibers and steel fibers.

- Engineering Specifications
SPECTER™ HP Synthetic Micro Fibers are specifically engineered for reducing plastic shrinkage cracking in concrete and mortars. The fibers control cracking caused by plastic shrinkage, plastic settlement, thermal expansion and contraction in concrete. SPECTER™ HP fibers also contribute to reduced water migration, and to increased surface resistance to impacts, abrasion and shattering. The fiber manufacturer must document evidence of compliance with building codes in accordance with ICC-ES AC32, and ASTM C1116/C1116M, Section 4.1.3, Type III. SPECTER™ HP Synthetic Micro 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 decrease rebound
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™ HP Synthetic Micro Fiber is 0.5 lb/yd3 (0.3 kg/m3 ).
- Mixing: SPECTER™ HP Synthetic Micro 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. When using SPECTER™ HP Fibers, please follow standard mixing procedures as specified in ASTM C94/C94M. Standard practices detailed in ACI 302 for placing, finishing and curing concrete should be followed when using SPECTER™ HP Fibers.
