Abstract

An analysis apparatus, an analysis method, and an analysis program by which even unskilled ones can perform quantitative analysis of a composition of high-performance cement with high precision. An analysis apparatusfor performing quantitative analysis of components of cement, includes: a content percentage conversion unitfor converting content percentages of major elements of a cement sample to content ratios of main crystal phases composing the cement sample by predetermined formulae, the content percentages being obtained as an elemental analysis result; a scale factor estimation unitfor estimating initial values of scale factors of Rietveld analysis from the content ratios of main crystal phases obtained in the conversion; and a Rietveld analysis unitfor performing Rietveld analysis with respect to an X-ray diffraction measurement result of the cement sample using the initial values of scale factors previously been estimated to calculate content percentages of respective phases of the cement sample.
