This standard specifies the determination of loss of ignition (LOI),SO3,insoluble residue (IR),SiO2,Fe2O3,Al2O3,CaO,MgO,TiO2,Cl-,K2O,Na2O,S2-,MnO,P2O5,CO2,ZnO,F-,free calcium oxide (fCaO),and SrO by chemical analysis methods of cement,X-ray fluorescence analysis method and inductively coupled plasma emission spectrometry.The chemical analysis methods of cement are divided into reference method and alternative method.If multiple determination methods are listed for the same composition,the reference method shall prevail in case of any disputes.
This document describes methods which apply principally to common portland cement,but which can also be applied to its clinker and raw meal.They can also be applied to other kinds of cement and materials,the standards for which call up these methods.
