摘　　要：利用XRD、DTA等手段研究了江西红泥岩的物相组成和热分解特征,测定了不同温度活化红泥岩的火山灰活性及活化红泥岩胶凝材料的物理力学性能。研究结果表明,江西红泥岩的主导粘土矿物为白云母,其适宜活化温度为900℃;活化红泥岩在水泥熟料激发条件下呈现优良的胶凝性能。The physical phase composition and thermal dessociation characteristics of the red mudstone from JiangXi were investigated by XRD, DTA method. The pozzuolana activity of the red mustone activated in different temperature has been measured. The physical and mechanical properties of cementing material using red mudstone has also been tested. The results show that the main clay mineral of red mudstone is muscovite. The optimum burning temperature of red mudstone is 900℃.The red mudstone at action of cement clinker shows good cementing properties.
