Performance characteristics of polyolefin fiber reinforced concrete
This paper presents an evaluation of the performance characteristics of a recently developed polyolefin fiber reinforced concrete. The performance of fresh concretes and the properties of hardened concretes with and without fibers are compared. A comparison is also made between the non-metallic polyolefin fiber reinforced concrete and steel fiber reinforced concrete. The test program on fresh concrete included: slump, concrete temperature, air content, vebe time, and unit weight. The hardened concrete properties evaluated were: compressive strength, static modulus, modulus of rupture, load-deflection curves, first crack toughness, strength and post crack behavior, ASTM toughness indices, Japanese toughness index, equivalent flexural strength, fatigue strength and impact strength. Polyolefin fibers performed well in the mixing sequence without causing any balling or segregation. The hardened concrete properties evaluated were: compressive strength, static modulus, modulus of rupture, ductility and toughness were greatly improved over the plain and steel fiber reinforced concrete.
