【摘要】 研究了测定熟料中二次游离氧化钙的条件。结果表明 :只要增大分析试样的细度 ,保证足够长的萃取时间 ,用甘油 乙醇法和乙二醇 乙醇法都能测定出熟料中的二次f CaO ,乙二醇 乙醇比甘油 乙醇萃取速度快。更多还原

【Abstract】 The method of measuring the content of secondary free lime is discussed in this paper.The results show that the content of secondary free lime in cement clinker can be measured through increasing the fineness of cement clinker by two methods,glycering ethanol method and glycolethanol method.Moreover,glycol ethanol method is more sensitive for measuring the content of secondary free lime than glycerine ethanol method.更多还原
