AR Glass Fibers
$17.50 - $6,800.00
PVA (Polyvinyl Alcohol) fibers are an ultra high performance fiber for concrete and are unique in their ability to create a fully-engaged molecular bond with mortar and concrete that is 300% greater than other fibers. Specifically designed for use in concrete products for the purpose of controlling plastic shrinkage, thermal cracking and improving abrasion resistance they meet the requirements of ASTM C-1116, Sec. 4.1.3 and AC-32 at 1.0 lb ( .45kg) per CY.
Mixing - add directly to the mixing system during or after the batching of the ingredients and mix at high speed for a minimum of five minutes. Additional mixing does not adversely affect the distribution or overall performance of the fibers. A water reducer or super-plasticizer is recommended in concrete products where improved workability and finish are desired.
Storage & Shelf Life - store in a dry location, protect product from the rain.

PVA fiber troweled table top
In a recent troweled a concrete tabletop, I evaluated the performance of PVA fiber within my mix design, and the results were impressive. I used PVA Fiber 15 at a 0.25% loading rate and PVA 100 at 0.7% (by dry weight). Both grades blended seamlessly into the mix, showing excellent stealth characteristics. Virtually invisible in the finished surface while still providing noticeable internal reinforcement. During placement and troweling, the fibers remained well-dispersed with no visible fiber fuzz or surface disruption, maintaining a clean, professional finish. The addition of PVA fiber enhanced crack resistance, surface cohesion, and structural integrity of the slab without sacrificing workability. When combined with C64, the mix showed perfect wet-out, improved cream migration, and significantly reduced air entrapment, leading to a smoother, denser surface. Overall, PVA fiber performed exceptionally well, delivering both functional reinforcement and aesthetic quality — a true “stealth fiber” solution for high-performance decorative and structural concrete applications.
