Product Description

SPECTER™ 3.5 Synthetic Micro Fiber is a true “Best-in-Class” fiber for reinforcement of concrete. FABPRO’s unique technology combines ultra-thin diameter with ultra-high strength, resulting in the highest level of plastic shrinkage crack reduction at only 0.75 lbs per cubic yard of concrete. Millions of high tensile, high modulus filaments in every yard create an extremely dense, three-dimensional network in most cementitious applications. SPECTER™ 3.5’s superior ability to reduce early age cracking can be accomplished at a minimum dosage as low as 0.50 lbs per cubic yard, with optimum results at the recommended and engineered dosage rate of 0.75 lbs per cubic yard of concrete.

ENGINEERING SPECIFICATIONS

SPECTER™ 3.5 Synthetic Micro Fiber, when used at an appropriate dosage, provides excellent plastic shrinkage and early age crack reduction. The fiber is rust proof, alkali resistant, and compliant with industry codes when used in concrete mixed in accordance with ASTM C94/C94M.

SPECTER™ 3.5 Synthetic Micro Fiber should be specified for use in concrete slabs:

To control bleed water
To reduce plastic shrinkage cracking
To increase abrasion resistance
To improve impact resistance
To reduce permeability

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™ 3.5 Synthetic Micro Fiber is 0.75 lb/yd³ (0.45 kg/m³). It can be used at dosage rates from 0.5 lb/yd³ (0.3 kg/m³) up to 1.0 lb/yd³ (0.6 kg/ m³).

MIXING

SPECTER™ 3.5 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 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™ 3.5 Fibers.

PACKAGING

SPECTER™ 3.5 Synthetic Micro Fibers are packaged in pre-weighed degradable 0.5 lb (0.23 kg), 0.75 lb (0.34 kg) and 1.0 lb (0.45 kg) bags that can be added directly to the mixing system.

SPECTER™ 3.5 Fibers are packaged in ultra-durable, double-walled boxes, palletized and stretch-wrapped with corner boards to prevent damage from shipping and handling.
