Utilization of granite scraps and minor clay tailings to prepare closed-pore foam ceramic was investigated using SiC as foaming agent. The foam ceramic presented promising results with a bulk density of 237.4 kg/m 3 , compressive strength of 0.85 MPa, flexural strength of 0.42 MPa, porosity of 83.31%, water absorption of 2.21% and thermal conductivity of 0.051 W/(m k), which had good potential application in the field of building insulation.
