<p><P>PROBLEM TO BE SOLVED: To provide a method for producing cement clinker by using waste materials such as nonferrous slag and coal ash as raw materials in which the cement produced by using the obtained cement clinker is prevented from occurrence of a phenomenon that the mortar compressive strength lowers. <P>SOLUTION: The method for producing cement clinker comprises the steps of: measuring the Ti content of each of raw materials (minerals, waste materials, etc.) to be used for producing the cement clinker by X-ray fluorescence analysis; and adjusting a mixing ratio of each of raw materials so that the Ti content of the cement clinker obtained by firing becomes≤1.0 mass% in terms of TiO<SB>2</SB>. When titanium slag having high Ti content is used as the raw material, a good result can be achieved particularly according to this method. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
