Accurate, rapid methods for controlling and determining composition are necessary to aid in classification of cements and for correlation of performance characteristics with composition. X-ray fluorescence (XRF) is used to adjust the raw material proportions and to control the process conditions. The aim of the present study was to establish a reliable analytical program by X-ray fluorescence spectrometry, based on the choice of a well-defined range of standards, which are used to control the quality of the clinker. The results showed a second order polynomial regression model that could properly interpret the experimental data with an R2 value >0.97 even after correction for some elements. The results obtained indicate the reliability, reproducibility, and the ease of use of the established program.
