In this paper, a new type of foam concrete (FC) incorporating ceramsite as a lightweight coarse aggregate was prepared, i.e. ceramsite cellular concrete (CCC). An experimental research was conducted on its thermal properties to clarify the correlation between thermal conductivity and density, compressive strength, thermal storage coefficient and to discuss the influence of ceramsite volume proportion on CCC. Results showed that predictable polynomial models between thermal conductivity and density, compressive strength, and a good linear dependence of thermal storage coefficient on the thermal conductivity can be attained. In addition, it was corroborated that, for the CCC with the design density of 600 kg/m3, the appropriate volume proportion of ceramsite was 45% to present the better influence on thermal conductivity and compressive strength.
