ADVANTAGES
Advantage Macrosynthetic Fibers
♦
meet the requirements of ASTM C1116, Section 4.1.3 and Note 2 for Synthetic Fiber Reinforced Concrete.
Advantage Macrosynthetic Fiber utilizes to the ultimate the four unique properties of macrosynthetic fibers; chemistry configuration, length and dosage rate in a special package that yields excellent ASTM Test Method C1609 results. 1. Chemistry - A blend of polypropylene and polyethylene resins. 2. Configuration - An embossed tape fiber with critical width and thickness dimensions to maximize bond. 3. Length - Available in 2 lengths; 1.5” and 2.0”. 4. Dosage Rate - Minimum recommended dosage rate of 3.0 pcy, with a typical working range of 3.0 pcy to 6 pcy and an upper limit of 16 pcy.
There is an available series of engineering test reports providing results of ASTM Test Method C1609 or ASTM Test Method C1399. These reports provide a set of comprehensive results at a number of dosage levels that will provide the engineer an opportunity to select the optimum dosage level for a given application. For further assistance please contact GRT Technical Support.
Optimizing these properties produces a macrosynthetic fiber with excellent dispersion and finishing properties.
Dosage will vary from 3-10 lbs. per cubic yard.
GRT Recommends that when using macrosynthetic fibers that a trial mix be fabricated at the ready mixer’s laboratory using the ingredients and proportions approved for the project. GRT suggests the use of a mid-range or hi-range water reducer. A vibrating screed or laser screed will promote uniform density of the concrete and ensure fiber encapsulation at the slab surface.
ADDITION RATES GRT will provide technical support in selecting the appropriate Advantage Macrosynthetic Fiber dosage based on the specification of the project and the requirements of the engineer.
