Constituents of cement covered by this document shall fulfil the requirements specified in Clause 5 of
EN 197-1:2011.
However, the following requirement for limestone (L, LL) replacing 5.2.6 a) of EN 197-1:2011 shall apply:
The calcium carbonate (CaCO3) content calculated from the calcium oxide content shall be at least 40 % by mass and the sum of calcium carbonate and magnesium carbonate (CaCO3 and MgCO3) content calculated from the calcium oxide and magnesium oxide content respectively shall be at least 75 % by mass.
The composition of Portland-composite cement CEM II/C-M and Composite cement CEM VI covered by this document is specified in Table 1.
5 Requirements
Cements covered by this document shall fulfil the requirements specified in 7.1, 7.2 and 7.4.1 of EN 197-1:2011.
The requirements listed in Table3 of EN 197-1:2011 for low early strength, indicated by L, are applicable for CEM II/C-M and CEM VI cements.
In addition, cements covered by this document shall conform to the requirements listed in Table 2.
6 Standard designation
Cements covered by this document shall be designated by at least the notation of the cement type as specified in Table 1 and the Figures 32,5, 42,5 or 52,5 indicating the strength class. In order to indicate the early strength class the letter L, N or R shall be added as appropriate.
When in the same factory a manufacturer produces different cements complying with the same standard designation, these cements receive an additional identification in the form of a number or of two lower case letters, between brackets, in order to distinguish these cements from each other. For the numbering system, this number should be 1 for the second certified cement, 2 for the next, and so on. For the lettering system, the letters shall be chosen in such a way as to avoid confusion.
Low heat cement in accordance with 7.2.3 of EN 197-1:2011 shall be additionally designated by the notation LH.
EXAMPLE 1
Portland-composite cement CEM ll/C-M containing in total a quantity of silicious fly ash (V) of between 16 % and 44 % by mass and a quantity of limestone (LL) of between 6 % and 20 % by mass and of strength class 32,5 with high early strength and a low heat of hydration is designated by:

EXAMPLE 3
Composite cement CEM VI containing in total a quantity of granulated blast furnace slag (S) of between 31 % and 59 % by mass and limestone (L) of between 6% and 20% by mass and of strength class 32,5 with high early strength is designated by:
Composite cement EN 197-5 – CEM VI (S-L) 32,5 R
EXAMPLE 4
Composite cement CEM VI containing in total a quantity of granulated blast furnace slag (S) of between 31% and 59% by mass and natural pozzolana (P) of between 6% and 20% by mass and of strength class 42,5 with low early strength is designated by:
Composite cement EN 197-5 – CEM VI (S-P) 42,5 L
7 Conformity criteria
For cements covered by this document the conformity criteria specified in Table 2 and in Clause 9 of
EN 197-1:2011 shall apply. In particular, conformity criteria specified for “all cements” in
EN 197-1:2011 shall also apply for cement covered by this document.
The conformity of cements covered by this document should be demonstrated by:
— factory production control, including product assessment, in accordance with Clause 4 of
EN 197-2:2020;
— assessment of the performance of the cement in accordance with 5.1 of EN 197-2:2020;
