Suitability of selected natural fibres for concrete performance improvement.

Abstract

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.
