Abstract:Fibre-reinforced self-compacting concrete uses the flowability of fresh concrete to improve fibre orientation, thereby enhancing toughness and energy absorption capacity. In the past few years there has been a boost in the development of concretes with macro-synthetic fibres added. In this paper, the mechanical properties of self-compacting concrete with low, medium and high fibre contents of macro polyolefin fibres are studied. Their fracture behaviour is compared with plain self-compacting concrete. It is possible to fit this behaviour within the existing standards requirements. Dispersion obtained for mean fracture values among the different amounts was analysed using a fracture surface analysis and the amount and distribution of fibres.
