TL;DR: In this article, the authors investigated potential engineering benefits of the pioneering application of simply extruded recycled high-density polyethylene (HDPE) plastic fibres in structural concrete and found that the Fibres mainly contributed by providing the post-cracking flexural ductility and through improving serviceability properties of concrete such as the reduced plastic shrinkage cracking, drying shrinkage and water permeability.

...The reported residual post-cracking to peak strength ratios achieved by the HDPE FRC are satisfactory as they reach approximately 50% of the equivalent RL/Fcr strength ratio for steel fibre reinforced concrete and are about equal to the ratios reported for concrete reinforced with PP fibres [15, 31]....

TL;DR: In this article, the main concepts behind the structural rules for Fibre Reinforced Concrete structural design are briefly explained, and a New fib Model Code that aims to update the previous CEB-FIP Model Code 90, published in 1993, is presented.
Abstract: Although the use of Fibre Reinforced Concrete (FRC) for structural applications is continuously increasing, it is still limited with respect to its potentials, mainly due to the lack of International Building Codes for FRC structural elements. Within fib (Federation Internationale du Beton), the Special Activity Group 5 is preparing a New fib Model Code that aims to update the previous CEB-FIP Model Code 90, published in 1993, that can be considered as the reference document for Eurocode 2. The New Model Code includes several innovations and addresses among other topics, new materials for structural design. In this respect, FRC will be introduced. The Technical Groups fib TG 8.3 “Fibre reinforced concrete” and fib TG 8.6 “Ultra high performance FRC” are preparing some sections of the New Model Code, including regular and high performance FRC. This paper aims to briefly explain the main concepts behind the structural rules for FRC structural design.

TL;DR: In this paper, the number of fibers per unit cross-sectional area in steel fiber reinforced concrete specimens incorporating various volume fractions of fibers of different types was measured and the differences in fiber concentrations at different locations on the cross-section were assessed.
Abstract: Measurements were made on the number of fibers per unit cross-sectional area in steel fiber reinforced concrete specimens incorporating various volume fractions of fibers of different types. Based on statistical evaluation of the measured values, the differences in fiber concentrations at different locations on the cross section were assessed. Theoretical expressions were derived for the number of fibers per unit cross-sectional area in fiber reinforced concrete, with due consideration given to the effects of the surrounding boundaries. The effects of vibration on reorientation of steel fibers in concrete were investigated through comparisons betwen the computed and measured values of number of fibers per unit cross-sectional area.
