Ultra high performance concrete (UHPC) is a composite material that consists of Portland cement, silica fume, ultra-fine quartz powder, super- plasticizer and small sized steel fibers with low water to binder ratio and absence of coarse aggregates. Compared to conventional concrete, UHPC has superior properties such as strength, toughness and durability. In this paper, the principles for mixture design and properties including mechanical properties, dimensional stability and durability of UHPC are reviewed. The findings of this paper have significance for the manufacture and application of UHPC.
