| Abstract: |
| This study explored the feasibility of dried biogas sludge as a blowing agent in sintered block's material system to produce energy-efficient porous sintered shale block. The influences of biogas sludge dose, sintering temperature and soaking time on physical, mechanical and working properties of the sintered wall materials were studied. Results showed that biogas sludge could be used as raw material to product sintered block with excellent plastic forming ability. The blocks sintered with biogas sludge dose of 10% in mass at 1000 ℃ for 3 hours showed the best mechanical properties. All performance indexes of the product met the requirements of the national standards for sintered common bricks[MU10(GB 5101-2003)] and the environmental protection standards. These results could shed light on new utilization of biogas sludge. |
