| 英文摘要 | In this study, the compressive strength of a coal metakaolin Bayer red mud complex (referred to as CMK-RM complex) was tested by varying the coal metakaolin content. The compressive strength of the CMK-RM complex increased with the increase in the coal metakaolin content and age. The Gauss Markov linear model was used to establish a binary prediction model for the compressive strength of the CMK-RM complex. The relationship between the compressive strength of the CMK-RM complex and the coal metakaolin content, along with age, was established. The error between the measured and predicted values was approximately 5%. In addition, combined with X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and chemical hydrated reactions of coal metakaolin, the phase composition and microstructure of the CMK-RM complex were analyzed. Thus, the strength mechanism of the coal metakaolin-solidified Bayer red mud was clarified. This study explains the reasons for the change in the compressive strength of the CMK-RM complex in terms of the strength mechanism. |
