Abstract：The effect of dielectric materials on the properties of ultra-high performance concrete(UHPC)subjected to standard and microwave curing was analyzed and compared.The results showed that the mechanical properties and durability of UHPC were improved under microwave curing for a short time,and the properties of UHPC prepared with 0.3 mol/L NaCl solution and SiC sand were improved more obviously.In terms of microstructure,UHPC prepared by high dielectric materials can generate more hydration products with denser structure under microwave curing,so as to optimize the matrix structure,fill the pores and improve the development of performance.
