Relationship of Polypropylene Fiber Reinforced Concrete to ...

1988-8-1  A new term, "Perm Point," explains the influence of the fibers on permeability. Subsidence cracking over steel reinforcement increases permeability and accelerates corrosion, whereas polypropylene fiber reinforced concrete reduces this phenomenon. Results suggest an interrelationship exists among permeability, cracking, and steel corrosion.
