    Ultra-high performance concrete (UHPC) is a new cement-based composite material with ultra-high strength, high toughness, and excellent durability. Low water-to-binder ratio and large amount of fine particles in UHPC lead to some problems like high viscosity of fresh paste, fiber cluster issue, and difficulty in pumping, etc.. This is not beneficial to the homogeneity of concrete and fiber strengthening and toughening of UHPC, and restricts the in-situ placing and application of UHPC. This review represented the rheological properties of UHPC from aspects of rheological parameters and models. Based on the influence of water-to-binder ratio, chemical admixtures, mineral admixtures, fiber and aggregate characteristics on the rheological properties of UHPC, the techniques in regulating the rheological behavior of UHPC were analyzed. Such techniques include regulating water film thickness, regulating paste film thickness, reducing viscosity of interstitial fluid, adding viscosity modifier, and changing fiber characteristics. In addition, the rheology regulation mechanisms associated with these techniques were also discussed.
