Résumé
[EN] Fibers are one of the most prevalent methods to enhance the tensile capacity of concrete. Most researchers focus
on steel fiber reinforced concrete which is costly and easily corroded. This study aims to examine the performance
of polypropylene fiber reinforced concrete through different tests. PPFs were added into concrete blends in a
percentage of 1.0%, 2.0%, 3.0%, and 4.0% by weight of cement to offset its objectionable brittle nature and improve
its tensile capacity. The fresh property was evaluated through slump cone test and while mechanical strength was
evaluated through compressive strength, split tensile strength flexure strength, and flexure cracking behaviors after
7-, 14-, and 28-days curing. Results indicate that slump decrease with the addition of PPFs while fresh density increase
up to 2.0% in addition to PPFs and then decreases. Similarly, strength (compressive strength; split tensile strength,
and flexure strength) was increased up to 2.0% addition of PPFs and then decrease gradually. It also suggests that
Ductility; first crack load, maximum crack width, and load-deflection inter-relations were considerably improved due
to incorporations of PPFs.
