Abstract: This paper studies the improve effects of three admixtures on the shrinkage property of ultra-high performance concrete (UHPC), and studies the influence of the mechanical properties. The results show that compound calcium sulphoaluminate hydrate-calcium hydroxide expansive agents with magnesium oxide expansion agent into UHPC, has no adverse effects to the mechanical properties of UHPC, also improves shrinkage properties; Super absorbent polymer (SAP) improves shrinkage properties of UHPC, but has adverse effect on the mechanical properties, the optimum mix amount should be determined in practical applications.
