| 摘要: |
| 以钢渣和废黏土砖为主要原料,制备了CaO-SiO2-Fe2O3系固废陶瓷,旨在减轻环境压力,降低瓷质陶瓷砖的生产成本。并通过同步热分析(TG-DSC)、X射线衍射(XRD)和扫描电子显微镜(SEM)等表征手段系统研究了升温速率对固废陶瓷砖的微观结构及宏观力学性能的影响。结果表明:当烧结温度达到1 190 ℃时,陶瓷试样的吸水率达到最优值0.057%,并且断裂模数显著提高,达到69.21 MPa。当0~1 000 ℃的升温速率为25 ℃/min,1 000~1 190 ℃的升温速率为1.5 ℃/min时,制备的陶瓷试样具有最优的吸水率0.091%和断裂模数72.45 MPa。研究结果为钢渣和废黏土砖陶瓷材料的制备工艺优化提供了参考。 |

| Abstract: |
| CaO-SiO2-Fe2O3 solid waste ceramics were prepared from steel slag and waste clay bricks as the main raw materials with the aim of alleviating environmental pressure and reducing the production costs of porcelain tiles.The effects of heating rate on the microstructure and macroscopic mechanical properties of solid waste ceramic bricks were systematically studied by simultaneous thermal analysis (TG-DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM).The results show that when the sintering temperature reaches 1 190 ℃, the water absorption rate of the ceramic specimen reaches an optimal value of 0.057%, and the flexural strength is significantly increased to 69.21 MPa. When the heating rate of is 25 ℃/min from 0 to 1 000 ℃ and 1.5 ℃/min from 1 000 to 1 190 ℃, the prepared ceramic specimen exhibits an optimal water absorption rate of 0.055% and a flexural strength of 72.45 MPa. The results of this paper provide valuable insights for the optimization of the preparation process of steel slag and waste clay brick ceramic materials. |
