Reuse of Municipal Solid Waste Incineration Fly Ash in Ceramic Brick

摘要：

In this work, macro-performance and leaching toxicity of ceramic bricks using MSWI fly ash (municipal solid waste incineration fly ash) as a blending were studied. It is found that ceramic bricks, with 25％ fly ash added and sintered between 960℃ and 1000℃, register compressive strengths between 20.1 Mpa and 18.2 Mpa, and water absorptions between 7.3％ and 6.7％. Besides, the bricks show excellent resistance against leaching, in accordance with HVEP standard, of heavy metals with Cd and Hg below the low detection limit, Pb<0.0141ppm and Zn<0.138 ppm. These results as a whole suggest that reuse of MSWI fly ash in ceramic brick is a potential means of adding value.
