Ultra high performance concrete(UHPC)is a new type of cement based composites with high strength and excellent durability.Firstly,this paper introduces the development history and technical performance of UHPC,then application of UHPC in lifeline engineering is summarized: the UHPC application examples of 18 bridges abroad; the application of UHPC in bridge joints and bridge deck pavemen; advantages of its anti-permeability and frost resistance in combination with the durability of UHPC in pipeline transportation.Based on this,the paper makes an improvement on the UHPC concrete formula,which makes it easier to be popularized in China,and 2 sets of UHPC-ECC composite pipe specimens were designed and tested for the first time.Experiments showed that the composite pipe has advantage of high strength,corrosion resistance,no leakage,and it can be widely used in the field of petroleum and hazardous chemicals transportation and so on.
