Typically the dosage rate will be 1 1/2 lbs/cu. yd. of concrete. Mixing of the fibers needs to be done at the job site as excessive mixing time can cause damage to the fibers.

This chopped strand is design for use in Fiber Reinforced Concrete (FRC) for plastic shrinkage crack control. It is not intended for general use in GFRC
13H103 Chopped Strand
Designed for fast dispersion into individual filaments on mixing in aqueous slurries. Particularly suitable for asbestos replacement applications and can be incorporated into face mix slurries to
help reduce surface crazing. Strand is wet cut and has
residual moisture.
Available in 6 and 13mm (1/4 and ? inch) lengths.
S750
The letter P in the product code states that the filament diameter is 18 microns as opposed to all other products which have 13 micron filament diameters. This makes it our heaviest available
strand. It has the highest integrity and is most resistant to filamentization during mixing and processing. It is particularly suitable for spray-premix.
Available in 13, 19 and 25 mm (1/2, ? and 1 inch) lengths.
PH901X
High integrity strand, designed for lower glassfiber content applications, such as stucco and surface bonding. It has half the number of filaments per strand that H530X, so it provides twice the
number of strands for same weight content as H530X. This can create workability difficulties at higher fiber contents. However, this feature can maximize strengths in low fiber content composites.
The finer strand is less visible at the surface, which is of benefit in stucco applications.
Available in 13mm (1/2 inch) length.
H350Y
High integrity strand, designed for premix applications such as premix casting and premix spraying. Available in 13, 25 and 38 mm lengths (1/2, 1 and 1 1/2 inch). Strand length is given by the
first one or two digits in the product code.
Example: 13H530X = 13 mm (1/2 inch) product.
H530X
Basically determines the number of strands per unit volume for a given weight percent. Generally the more strands per unit volume the higher the flexural strength but mix workability is usually
reduced.
The last letter in the product code gives the number of filaments per strand as follows: (Z = 50 Filaments per strand, Y = 100 Filaments per Strand, X = 200 Filaments per Strand)
Number of Filaments per Strand.
These products are usually confined to low fiber content mixes (< 2% by weight), or high water content mixes where the excess water is removed, such as in vacuum de-watering processes commonly used to manufacture asbestos cement and calcium silicate products.
These are water dispersible Strands that are designed to break down into individual filaments when it is added to water or aqueous mixes.
Strands designated by S in the product code.
These are high integrity strands that are designed to resist breaking down during mixing and processing so that it stays basically as a bundle of filaments. These products are particularly suitable for Premix and other mortar and concrete reinforcement applications.
Strands designated by H in the product code.
