    Abstract：The small particle size of waste expanded perlite is used to prepare lightweight partition board. The influence law of small expanded perlite admixture，fly ash content and total water/binder ratio on volume density，compressive strength and thermal conductivity of lightweight partition board is studied. The content of the small expanded perlite is in the range of 33.3%~41.7%.The content of fly ash is in 39%. The scope of the total water/binder ratio is 1.1~1.4. The production shows that the compressive strength ranges from 3.8~6.9 MPa，the dry density ranges from 706~827 kg/m3，the thermal conductivity is in a range of 0.1513~0.1859 W/（m·K）.
