摘要：Steel slag, fly ash and lime were chosen as pretreatment and grinding materials of fluorgypsum, then the grinding effect and cementitious property of fluorgypsum were studied. PH of pretreatment fluorgypsum increased to 8 when 1.5% lime, 5% steel slag and 12.9% fly ash were added. Specific surface area, fractal dimension and medium diameter of the modified fluorgypsum reveal that the best grinding aid is steel slag. SEM analysis show that there were still large particles when 1.5% lime or 12.9% fly ash were added in fluorgypsum and grinding, the fluorgypsum particles sizing were small with distribution uniformity after grinding when it was pretreated by 5% steel slag. Mortar strength results show that the fluorgypsum with 5% steel slag had good strength after pretreating and grinding.
