Jun 08,  · 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.

We conclude that the use of polypropylene fiber generates the following changes in the properties of the concrete: 1) Increase in its tensile capacity; 2) Decrease in the workability of the concrete and, 3) Increased ductility of the concrete. Keywords: Compressive strength - concrete - polypropylene fibers.

with polypropylene fiber reinforced concrete as that in tensile strength, but the difference that dosage amount for which best result is achieved is 0.25%. There is about 80% increase in flexure strength by adding 0.20% fibers in concrete after which strength starts reducing with further increment in fiber ratios.

from high fiber surface area, close fiber spacing, excellent bonding within the cement matrix, high fiber tensile strength, and easy dispersion in concrete so it is always positioned correctly.
