Abstract: This paper addresses a sustainable development of an Ultra-High Performance Fibres Reinforced Concrete (UHPFRC), focusing on an efficient utilization of fibres. The design of the concrete mixtures is based on the aim to achieve a densely compacted cementitious matrix, employing the modified Andreasen & Andersen particle packing model. The binary and ternary fibres hybridization is designed to reinforce the concrete matrix. Then, the flexural behaviour and toughness of the developed UHPFRC are measured and analysed. The results show that the UHPFRC with hybrid fibres has much better flexural behaviour than the mixture with a single type of fibre. Nevertheless, the flexural toughness of UHPFRC is dominated by the hooked steel fibres. Due to the specific characteristics of UHPFRC, the JSCE SF-4 standard is found more suitable than ASTM C1018-97 to be used to evaluate the flexural toughness property of the sustainable UHPFRC.
