    Abstract：New cement-based composite wall material with bulk density of 800 kg/m3 is prepared by using cement as cementing material，fly ash and slag as admixture，sand and cellular glass beads as fine aggregate，and inorganic insulation fireproof coarse aggregate as insulation fireproof coarse aggregate. Based on the requirements on strength，water absorption and thermal performance，orthogonal experiment method is used to select the optimal mix，and the influence law of insulation fireproof coarse aggregate，air entraining agent content，glass beads and sand content on the physical properties and thermal insulation properties of the material is discussed. The results show that by optimizing composite wall material both with excellent physical properties and good thermal insulation properties can be developed.
