Abstract： When preparing the shale pottery cement mortar,the glazed hollow bead constant volume was used to replace the shale pottery ranging the rate from 0% to 100%,and their effects on the workability,mechanical property,durability and thermal insulation performance were studied.The experiment results showed that the glazed hollow bead could be reduced segregation degree and improved compressive strength of the mortar when the replacing rate was less than 50%,but the density and thermal conductivity of the mortar was increased.The consistency,bond strength and shrinkage rate of the mortar was increased with the increasing of replacing rate of the glazed hollow bead.
