| Abstract: | With Wuhan municipal wastewater treatment plant sludge and fly ash to prepare lightweight aggregate. Calcined in a certain system, adjust the ratio of raw materials, the lightweight aggregate＇s packing density can he prepared as 763 kg/m3 , water absorption is less than 6%, cylinder compressive strength is 6. 9 MPa. The resource utilization of sewage sludge is effectived. |
