Ultra-high performance concrete (UHPC) is a cement-based composite building material with excellent durability and mechanical properties, but its autogenous shrinkage and drying shrinkage phenomenon have become a common problem in practical engineering. In order to solve this practical problem, new mineral admixtures and admixtures are usually added to UHPC, and the shrinkage of UHPC is effectively improved.
