100% virgin homopolymer polyvinyl-alcohol monofilament fiber
Feature:
Color: Light yellow
Diameter: 16μm (2.0±0.25dtex)
Length of fiber: 6mm,8mm, 12mm
Specific gravity: 1.30g/cm3
Elongation at break: 7-15%
Shape: Bunchy monofilament
Tensile strength: ≥ 11.5cn/dtex
Elastic modulus: 31-40Gpa
Alkali, Acid&sal resistance: High
Decrease the plastic shrinkage of concrete, reduce more than 90% of concrete plastic shrinkage
Increase more than 70% of the concrete impact resistance
Increase anti-permeability of concrete to S12
Increase 5-10% of its bending strength
Increase the toughness and extensibility of the concrete
Application
Pavement of expressway and road
Industrial and residential building
Airport runways and aprons
Concretes structures in the area of water conservancy
Shot-concrete for inner wall of tunnels and mines
Bridge structures and deck pavement
Products use:
Mixing design and procedures: PVA fiber reinforcing is a mechanical, not a chemical process,
The addition of PVA fiber may have an effect on slump, the use of other admixtures may be necessary to maintain both slump and workability.
PVA fiber are added to the mixer after batching the other concrete material, before the addition of water
Mixing time should be a little longer than that without the additional of fibers
The standard application rate for PVA fibers is 1.2kg per cubic mater of concrete
