| Abstract: | This paper studied the influence of hollow cenospheres and perlite to the thermal insulation mortar by replacing cement to hollow cenospheres and vitrified beads to perlite.The experiment of the performance of hardened mortar（density,intensity,ratio of compressive strength,water absorption,thermal conductivity coefficient,ect.） has been carried based on keeping the fluidity of fresh mortar.The research shows that,when the replace rate of hollow cenospheres is 25% and the replace rate of perlite is 45%,the performance of the mortar could meet the requirements of the JG/T283-2010 to light mortar,at the same time,the thermal conductivity coefficient has reached a lower value. |
