Summary:PROBLEM TO BE SOLVED: To provide a method capable of easily and accurately determining the quantity of an admixture in mixed cement.SOLUTION: The quantity determining method of an admixture in mixed cement employs an X-ray diffraction Rietveld method. In this method, an external standard method based on the X-ray diffraction Rietveld method is used, and portland cement contained in the mixed cement is used as a standard substance in the external standard method. Preferably, the quantity determining method includes a process of calculating the G factor in the portland cement, and a process of calculating the mass ratio in each of crystal phases constituting the mixed cement.SELECTED DRAWING: None 【課題】簡便でかつ高精度に混合セメント中の混合材を定量することができる方法を提供する。【解決手段】Ｘ線回折リートベルト法を用いた、混合セメント中の混合材の定量方法であって、上記Ｘ線回折リートベルト法に基づいた外部標準法を用い、かつ、上記外部標準法における標準物質として、上記混合セメントに含まれているポルトランドセメントを用いる、混合セメント中の混合材の定量方法。該定量方法は、上記ポルトランドセメントのＧファクターを算出する工程と、上記混合セメントを構成する各結晶相の質量割合を算出する工程を含むことが好ましい。【選択図】なし
