摘　　要：在研究利用赤泥制备胶凝材料的基础上,向其中掺加煤矸石、粉煤灰、矿渣等矿物掺加料,利用XRD、SEM等现代测试技术,对混合胶凝材料体系的水化过程、水化产物及显微形态进行了分析和研究,揭示了煤矸石等掺加料对赤泥基胶凝材料体系力学性能的影响及其机理。On the basis of preparing cementitious material by the red mud, mineral admixture including coal gangue, fly ash and slag were added into the material. The hydration process, hydration produets and mierostrueture of the mixed eementitious system were analyzed and researched by using modem testing method as XRD and SEM etc. It revealed the influence and mechanism of mechanical properties of the mineral admixture on the red mud based cementitious material.
