为研究尾矿中硅酸盐矿物在蒸压建筑材料体系中的作用,通过 X 射线衍射、热重、扫描电子显微镜、能谱分析和红外光谱分析,对角闪石、拉长石、钠长石和黑云母的蒸压反应活性进行了探讨。结果表明：在180℃蒸压8 h 的条件下,拉长石和钠长石具有蒸压反应活性,角闪石和黑云母不具有蒸压反应活性；拉长石的蒸压产物有水钙铝榴石和斜托贝莫来石,钠长石的蒸压产物有托贝莫来石,蒸压产物相互连接有助于提高结构致密性；反应生成的托贝莫来石矿物均含有 Na,具有一定的固碱作用。

To study the effect of silicate minerals in tailings on autoclaving construction materials, the autoclaving reaction activity of hornblende, labradorite, albite, and biotite was analyzed by X-ray diffraction, thermogravimetry, scanning electron microscopy, energy dispersive X-ray spectroscopy, and infrared spectrometry. The results show that at 180 ℃ for 8 h, labradorite and albite have autoclaving reaction activity, but hornblende and biotite do not. Autoclaving products in the labradorite system contain hibschite and clinotobermorite, while in the albite system contain tobermorite. These products connect together, which helps to improve structural compactness. Na exists in tobermorite minerals, indicating that the minerals have the function of alkali binding.
