UNE 80-265-1988 Chemical analysis and testing methods of cement. Determination of more than three components and cement-forming compounds (by means of selective dilution method)
The purpose of this standard is to describe a test method to determine the content of compounds in cements with more than three components. The method is applied to cements that have several components: clinker, secondary compounds (hydraulic, pozzolanic or inert) and setting regulator. The results obtained by this method can be considered quantitative if one of the following two conditions is met:
——that the slag content in the cement is zero;
——that the clinker content in the cement is greater than 60%. Note - This standard will be reviewed when the corresponding CEN standard comes into force.
