Effect of curing conditions on mechanical and shrinkage properties of UHPC

In recent years, ultra-high performance concrete has become a hot spot in the research and development of civil engineering technology, and curing conditions are one of the key links in the performance research of ultra-high performance concrete. In this paper, the effects of different curing temperatures at home and abroad on compressive strength, tensile strength and shrinkage values are mainly expounded. Through literature research, it can be seen that high-temperature steam curing, hot water curing, dry heat curing and combined curing can significantly improve the compressive strength and tensile strength of UHPC. Different curing temperatures have great influence on the shrinkage of UHPC, and with the increase of curing temperature, the shrinkage of UHPC will decrease, and most of the shrinkage occurs 14 days before curing.
