A tired perforated light-weight material is prepared with red mud, fly ash, silica fume as the main raw materials, and a certain amount of foam as additive, then shaped and tided. The influence of tiring temperature on the flexural strength, compressive strength, shrinkage and other properties of sample is studied. The firing mechanism is studied by scanning electron microscopy （SEM）. The results show that the optimum firing temperature is 1150 ℃, and for the best sample, its bulk density is 691 kg/m3, compressive and flexural strength are 4.2 MPa and 3.2 MPa, thermal conductivity coefficient is 0.110 W/（m· K）, firing shrinkage is 3.9 %.
