摘要：
The dry density and thermal conductivity of foamed concrete, of which dry density is less than 300kg/m3 were tested. The air-void structures of the foamed concretes were investigated by X-CT. The tested results were analyzed by using theoretical models for thermal conductivity of two-phase materials. The new equation was proposed and verified and it was applied to foamed concrete of which dry density is less than 300kg/m3. The results indicate that the predicted values agreed well with experimental ones. © 2020, Editorial Department of Journal of Building Materials. All right reserved.
