Polypropylene (PP) Fiber
Polypropylene fibers are filaments that are extruded from homopolymer or isotactic polypropylene polmers. They are cheap, abundantly available, and like all manmade fibers of a consistent quality.
Concrete offers many advantages regarding mechanical characteristics and economic aspects of the building. However the brittle behavior of the material is a negative characteristic in regards to seismic and other applications where flexible behavior is essentially required.
Adding flexible fibers into concrete mixtures is a common and effective way to counteract the brittle characteristics of concrete. PP fibers in concrete increase tensile strength, flexural strength, workability, bond strength, fracture properties, creep strain, and bleeding properties.
