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.

Review on the Durability of Polypropylene Fibre-Reinforced ...

Polypropylene fibre (PPF) is a kind of polymer material with light weight, high strength, and corrosion resistance. The crack resistance of concrete can be improved by adding PPFs. PPF can optimize the pore size distribution of concrete. As a result, the durability of concrete is significantly enhanced since PPF can block the penetration of water or harmful ions in concrete.

Shrinkage Behaviour of Fibre Reinforced Concrete with ...

Different types of fibres are often used in concrete to prevent microcracking due to shrinkage, and polypropylene fibres are among the most often used ones. If not prevented, microcracks can lead to the development of larger cracks as drying shrinkage occurs, enabling penetration of aggressive substances from the environment and reducing durability of concrete structures.
