Abstract
To realize the utilization of andesite tailings and solve the environmental problems caused by municipal solid waste incineration (MSWI) fly ash, both of them were selectively used as raw materials to prepare glass ceramics by sintering process. The effects of components on the properties of glass ceramics were analyzed. The results showed that glass-ceramic sample 21 prepared from andesite tailings and MSWI fly ash had the best performance, the bending strength was 94.8Mpa. At the same time, its acid and alkali resistance were the best, while the thermal conductivity was the lowest. The leaching of heavy metal elements in all the samples met the Chinese national standard. These results will provide some reference for the resource utilization of andesite tailings and MSWI fly ash.
