PVA reinforcing fibers

PVA Reinforcing Fibers, 5 lb bag 

Item #PV50001

• 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.
