Analysis apparatus, analysis method and analysis program

An analysis method for performing quantitative analysis of components of cement, comprising the steps of:

• receiving an elemental analysis result of cement sample, which is different from an X-ray diffraction result, and storing the received elemental analysis result;
• receiving the X-ray diffraction measurement result and storing the received X-ray diffraction measurement result;
• converting content percentages of major elements in a cement sample to content ratios of main crystal phases composing the cement sample by predetermined formulae, the content percentages being obtained from the elemental analysis result;
• executing an algorithm to estimate initial values of scale factors of Rietveld analysis based on a correlation between a content ratio of each crystal phase obtained by the conversion, which is the weight ratio of each main crystal phase, and the scale factor ratio of each main crystal phase;
• performing Rietveld analysis with respect to the X-ray diffraction measurement result of the cement sample using the estimated initial values of scale factors to calculate content percentages of respective phases of the cement sample;
• and
• outputting the content percentages as the Rietveld analysis result.
