Classification4.1 This specification applies to the following types ofblended cement that generally are intended for use as indicated.4.1.1 Blended hydraulic c

18、ements for general concrete con-struction.4.1.1.1 Type ISPortland blast-furnace slag cement.4.1.1.2 Type IPPortland-pozzolan cement.4.1.1.3 Type ITTernary blended cement.4.2 Reporting:4.2.1 The naming practice for blended cements shall bemade by adding the suffix (X) to the type designation under4.1

19、.1, where (X) equals the targeted percentage of slag orpozzolan in the product expressed as a whole number by massof the final blended product, within the allowable variation asstated in 14.3.4.2.2 The naming practice for ternary blended cements shallbe made by adding the suffixes (AX) and (BY) to t

20、he Type ITdesignation under 4.1.1, where:A is either “S” for slag cement, or “P” for pozzolan,whichever is present in larger amount by mass, andX is the targeted percentage by mass of constituent A, andB is either “S” for slag cement, or “P” for pozzolan, andY is the targeted percentage by mass of c

21、onstituent B.Both X and Y values are expressed as a whole number bymass of the final blended product, within the allowablevariation as stated in 14.3.
