The addition of fibres to reinforce concrete (FRC) is required when concrete structures may be submitted to other types of stresses beyond
the compressive. Post-crack tensile strength, resistance to abrasion and additional plastic deformation are examples of additional physical
and mechanical properties that can be required from concrete elements. Steel, glass and polymer fibres are the most common concrete
fibres at present. However, their high cost and low durability under abrasive conditions, along with their environmental impact are
disadvantages associated with these materials[1-3]. This work examines the potential replacement of these synthetic fibres with more sustainable natural fibres.
