DESCRIPTION

MACRO-PROTM is a highly modified fibrillated polyolefin tape fiber, which meets the definition of the new generation FRC, (i.e. macrosynthetic fibers). Macrosynthetic fibers move the envelope forward in 3-dimensional reinforcement performance. Standard fiber lengths are 1.5” and 2.0” and the dosage range is 3.0 to 11.0 pcy. Confidently embrace this new generation of concrete reinforcement with MACRO-PROTM.

Macrosynthetic Fibers are designed to perform at a higher level than the first- generation microsynthetic fibers. Two of the primary sources of improvement are the result of: one, an increased fiber length, a minimum of 1.5” (38mm) versus 0.75” (19mm) for microsynthetic fibers and, two, enhanced mechanical bonding due to an improved configuration.

The higher level of measured performance is demonstrated in post-first crack toughness where the fibers actually carry load across a crack created by an externally applied load. MACRO-PRO fibers have been designed to utilize the physical properties of both polypropylene and polyethylene resins in a highly modified fibrillated tape, where the main fibrils have been increased in cross-section versus conventional fibrillated products.

The modified fibrillation pattern paired with the blend of resins yields outstanding post first crack toughness numbers as measured by ASTM Test Methods C1399, C1550 and/or C1609. MACRO-PRO is a very versatile macrosynthetic fiber, showing excellent mixing and distribution properties. This product has a sparkling five (5) year record of use ranging from commercial to industrial and warehouse slab-on-ground and elevated steel deck applications as well as exterior slabs-on-ground such as roadways and truck terminals and precast products that include septic tanks and utility vaults.

MACRO-PRO replaces conventional secondary reinforcement, which includes wire mesh and #3 and #4 rebar when used as temperature-shrinkage reinforcement. The in-place cost differential always favors MACRO-PRO particularly when all of the cost components of placing the conventional secondary reinforcement are considered (including the concrete pump when calculating costs for slabs-on-ground). MACRO-PRO Fiber complies with ICC-ES AC32 where applicable, ASTM C1116 Type III, Section 4.1.3 and Note 2. ASTM C1399 and C1609 test data for the MACRO-PRO product are available.

ENGINEERING SPECIFICATIONS

Conforms to: ASTM C1116, Section 4.1.3 and Note 2.

Fiber Reinforcement and Concrete Additives: The UL Certificate of Compliance Number 20130305-R19202 (Report Reference R19202-20130305) certifies that representative samples of macrosynthetic fibers designated as Macro Pro have been investigated by UL in accordance with the Standard(s) indicated on this certificate.

Standards for Safety: UL263 Fire Tests of Building Construction and Materials. See UL Online Certifications Directory at www.ul.com/database for additional information.

GENERAL SPECIFICATIONS

MACRO-PRO Fibers should be added per engineer’s instructions or per standard government agency specifications with the dosage rate established by testing or as dictated by a standard specification. MACRO-PRO Fibers are packaged in pre-measured degradable bags that can be added directly to the mix. The weight of the pre-measured bags can be adjusted to meet the specific dosage rate established for a given project.

INSTRUCTIONS FOR USE

Concrete mixing plant personnel should establish the correct mix design based on the quantity of MACRO-PRO Fibers being added to the mix. Adjustments to the mix may be required and a mid-range or hi-range water reducer is recommended. MACRO-PRO fibers may be added to the concrete at any time before, during or after the batching process, with a single exception...bags may not be added at the same time as the cement. Minimum increase in mixing time may be needed to ensure complete dispersion of the fibers. Follow ASTM C-94, “Standard Specifications for Ready-Mixed Concrete” in assembling a homogeneous mix.
