This standard specifies the chemical analysis method and X-ray analysis method of cement. Cement chemical analysis is divided into benchmark method and substitution method. In case of dispute, the benchmark cement chemistry method shall prevail. This standard is applicable to general-purpose Portland cement, clinker and raw meal for the preparation of the above cement, and other cements and materials designated to adopt this standard.
