The poor tensile strength and brittle nature of cementitious composites restrict their use in civil engineering. The addition of fibres strengthens and increases the ductility of the composites. The random distribution of fibres in concrete prevents the initiation and propagation of cracks in concrete. In this study, experiments were conducted to assess the mechanical and fracture properties of a composite reinforced with polypropylene (PP) fibres. In the proposed study, polypropylene fibre with a cut-length of 12 mm is used to create composites. Five different PP fibre volume fractions 0, 2, 3, 4, and 5% were used. Cubes, modified briquette, and single edge notched bend (SENB) specimens were casted. The fracture properties of composites have been assessed in the current work using closed loop servo-controlled system. In order to get the load versus crack mouth opening displacement curves and to assess fracture toughness, the test was carried out under displacement control. Compressive strength, tensile strength, and fracture toughness tests were assessed on the composite specimens. The findings showed that PP fibres significantly enhanced post-peak behaviour and fracture toughness in a composite.
