PVA-7 Fibers, 1/4" (6mm) long - Sold by the lb

PVA reinforcing fibers-Long term shrinkage crack control

Fiber Length:  1/4" (6mm) long

Sold in 1 lb bag,

Recommended dose for face coats: .4% - .5% of cement weight

The only PVA fiber designed specifically for GFRC mist/face coats.  Reduces shrinkage cracks and increased impact strength while remaining invisable to the naked eye.  These PVA fibers are half the denier of our regular PVA's and are coated to disperse better reducing clumping.

• PVA fibers are a new, high performance fiber for concrete.  Like steel, these PVA fibers have high tensile strength and a greater modulus of elasticity than regular concrete.  Unlike steel, PVA fibers develop a molecular and chemical bond with the cement during hydration and curing.  This high bond strength makes PVA fibers very tough to pull out during bending or tension.  Studies published by University of Michigan researchers demonstrate PVA engineered cementitios composites with tensile strain capacity of 5% approximately 500 times that of normal concrete or fiber-reinforced concrete.
