Calcium silicate slag is the residue of process of pre-desilication alkali lime sintering applied in the high-alumina fly ash to extract the alumina. The quantitative phase analysis （QPA） of the calcium silicate slag has been performed by the Rietveld method based on the powder X-ray diffraction （XR...
