本文采用选择性溶液化学分析、X射线粉末衍射结合Rietveld法和核磁共振三种技术对两种F型粉煤灰的各种（玻璃态和结晶态）成分进行了定量分析。研究结果证实了技术的适用性，以追求的目标，同时提供进一步的洞察到灰的玻璃相的化学成分，以及这些材料的热历史的理解。最后，该文件证实了在先前的研究中建立的理由，关于灰的玻璃质成分是在控制其碱的反应性在制造过程中的“碱性水泥”。(C)2005爱思唯尔有限公司保留所有权利。
The various (vitreous and crystalline) components of two type F fly ashes are quantified in this paper using three techniques: chemical analysis with selective solutions, X-ray powder diffraction combined with the Rietveld method and nuclear magnetic resonance. The findings confirm the suitability of the techniques to pursue the objectives while providing further insight into the chemical composition of the vitreous phase of the ash as well as an understanding of the thermal history of these materials. Finally, the paper corroborates the grounds established in prior research for regarding the glassy constituents of an ash to be instrumental in the control of its alkali reactivity during the manufacture of 'alkaline cements'.
