    Abstract：The production of aerated concrete block using ceramic powder waste is studied in this work. Raw material properties，raw material ratio，foaming agent dosage，water slurry ratio，and maintenance methods are discussed. The optimum process parameters are determined. When the content of raw materials is 73.5% of powder waste，18% of quick lime，7% of cement，1.5% of gypsum，and dosage of aluminite powder is 0.9 kg/m3，water slurry ratio is 0.6，thermostatic steam pressure is 1.2~1.4 MPa，the produced aerated concrete block has the desiccated bulk density of less than 560 kg/m3 and compressive strength of more than 3.7 MPa.
