Polyester fiber can help a concrete mixture bridge cracks and retain useful behavior as the material deforms. Its effect depends on the fiber grade, shape, amount, dispersion, and bond with the cement matrix. For contractors and producers, the useful question is which measurable property the finished mixture needs to achieve.
