Accurate, rapid methods for controlling and determining composition are necessary to aid in classification of cements and for correlation of performance characteristics with composition. XRF is used to adjust the raw material proportions and to control the process conditions. The aim of this study was to establish a reliable analytical programme by XRF, 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 property 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.
