| Abstract: | In this paper, the chemical and mineral composition of the coal gangue from Huangshi City, Hubei Province, was systemically analyzed, and its quality and grade were evaluated. Experiments with different proportions of coal gangues as raw materials were carried out. The measurement and analysis of water absorption rate and rupture modulus of the porcelain bodies were made under the conditions of different dosages and sintering temperatures. The integrated analysis of performance indexes shows that the coal gangue of iron_rich sandstone from Huangshi City can be used to produce porcelain brick, with the quality consistent with the corresponding national quality standards on water absorption rate and rupture modulus of the porcelain bodies. The content of coal gangue in the porcelain brick can be as high as 80%. The water absorption rate of the porcelain bodies is lower than 0.3%, their rupture modulus is higher than 35 MPa, and their colors change from light red through dark red to purple brown. |
