Application Note: Determination of Limestone Addition in Cement Manufacture
7 March 2013

There is a growing demand and interest in the cement industry to monitor the concentration of limestone, of which calcium carbonate (CaCO3) is the main constituent in the final product. In this application note it is demonstrated that the combination of XRF and XRD in the same instrument can provide complete quality control of clinker and cement. Separate instruments or methods are no longer required resulting in significant savings from increased operator efficiency and lower running costs.
