Major oxides in finished cement

AppNote 1157: the analysis of finished Portland cement is demonstrated using the empirical approach.

Background

X-ray fluorescence (XRF) spectroscopy is a well established technique used in cement plants around the world. The technique is ideal for quality control (QA/QC) throughout the cement production process. Energy dispersive X-ray fluorescence (EDXRF) spectrometry is a routinely employed screening and quality control tool employed to ensure proper composition of incoming feedstocks, raw meal mixture balances, addition of gypsum and throughout the manufacturing process. EDXRF analyzers are also commonly deployed as backup instruments for WDXRF spectrometers used for final QC and certification.
