Abstract: A kind of high performance fiber reinforced cementitious composite, Ultra High Toughness Cementitious Composite (UHTCC), has attracted a lot of attention in the past two decades. This paper summarizes the research status that relates to the application of UHTCC in civil engineering structures, and introduces basic mechanical performance and durability of UHTCC firstly. To fulfill the requirements of different projects, UHTCC with various added functions and process have been developed. UHTCC has a good prospect of application and extension because of the special mechanical behavior, excellent durability and variety of processing. Current research achievements in the potential structural application of UHTCC and some practical application examples are emphasized, such as the novel use of UHTCC as protection cover to improve structural durability and as energy-dissipating material to strengthen structural seismic capacity, and for retrofit and repair of concrete structures.
