Researches demonstrate that fibers boost performance of concrete
incredibly. It’s determined that in literature steel fibers increase flexural
strength and energy absorption capacity of the cementitious composites. However
concrete highways consist of steel fibers in corrosive conditions eliminate
fiber’s effect. Therefore producers of polymeric fibers launch fibers which can
withstand corrosive environments and chemicals, and launch polyester and
polypropylene fibers alternative to steel fibers. This research intends to
determine the performance of concretes consist of polyester fiber,
polypropylene fiber and steel fiber against traditional concrete. For this
reason, fresh and hardened concrete properties of the concrete mixtures
produced with 0%, 1% and 2% are determined by laboratory tests. The mechanical
behaviors of these concrete specimens are investigated by compressive strength
and tensile strength tests on 150x150x150 mm cubic and 100x100x500 mm prismatic
specimens respectively. The abrasion resistance of the pavement concrete is
measured by Bohme abrasion test on 70x70x70 mm cubic specimens. Test results
showed that fibers are reinforced concrete against external effects which can be
occurred during the service life of the rigid pavements. Significant
developments are determined with the polymer fiber additives on concrete
abrasion resistance and mechanical behavior of concrete.
