Mechanical performance of concrete reinforced with polypropylene fibers (PPFs)

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