Overview
EN 197-5:2021 (CEN) specifies requirements for two cement types not covered by EN 197-1: Portland‑composite cement CEM II/C‑M and Composite cement CEM VI. Its scope covers cements intended for the preparation of concrete, mortar, grout and similar products while excluding common cements (EN 197-1), very low heat special cements (EN 14216), supersulfated cements (EN 15743), calcium aluminate cements (EN 14647) and masonry cements (EN 413-1). The standard supports sustainability objectives by enabling lower clinker content through defined combinations of supplementary cementitious materials (SCMs) and limestone.
Key topics and technical requirements
- Composition and constituents: Defines permitted mixes of clinker, SCMs (granulated blast‑furnace slag, fly ash, pozzolana, calcined clays, silica fume) and limestone. Typical composition ranges cover lower clinker content (about 35–64% depending on cement type) with SCMs and limestone making up the balance (SCM proportions up to ~59% and limestone up to 20% where applicable).
- Strength classes and early strength: Uses the familiar EN strength classes (32,5 / 42,5 / 52,5) with early strength designations L, N, R and optional low‑heat notation LH.
- Chemical limits: Limits on sulfate (SO3) and chloride contents apply; sulfate can be up to around 4.5% in certain compositions and chloride is normally limited to ≤ 0.10% by mass unless otherwise declared for specific CEM VI formulations.
- Testing & conformity: References EN 196‑2 for chemical analysis and EN 197‑2:2020 for assessment and verification of constancy of performance (factory production control, initial inspection, continuing surveillance, audit testing).
- Designation, marking & labelling: Specifies how to designate product type (e.g., “CEM II/C‑M (S‑V) 42,5 N – LH”), and what information must appear on packaging or delivery documents (standard designation, manufacturer/plant, weight, certification body).
Practical applications
- Use in structural and non-structural concrete, mortars and grouts where reduced clinker content or specific SCM combinations are desired.
- Supports sustainable construction by enabling cement formulations with lower embodied CO2 through higher SCM/limestone content.
- Informs material selection for engineers, specifiers and contractors needing compliance with European cement standards and project durability requirements.
Who uses this standard
- Cement manufacturers and formulators developing CEM II/C‑M and CEM VI products
- Construction materials laboratories and test houses
- Specifiers, structural engineers and architects selecting cements for concrete and mortar
- Certification bodies and regulatory authorities performing conformity assessment

European foreword
This document (EN 197-5:2021) has been prepared by Technical Committee CEN/TC 51 “Cement and
building lime”, the secretariat of which is held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2021, and conflicting national standards
shall be withdrawn at the latest by November 2021.
The purpose of this document is to specify the requirements for the two more recently developed
cement types, Portland-composite cement CEM II/C-M and Composite cement CEM VI, which are not
covered by the European Standard EN 197-1:2011. The fitness of these cement types for the intended
use to produce structural concrete (reinforced or not) has been experimentally assessed by testing
programs developed in the frame of CEN/TC 51/WG 6, the results of which have been included in three
dossiers [5, 6, 7] approved by CEN/TC 51.
The cement types and strength classes defined in this document allow the specifier and/or the user to
fulfil objectives of sustainability for cement-based constructions and to minimize the use of natural
resources in accordance with local conditions of production.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Introduction
It is recognized that different cements have different properties and performance. The performance
tests available at the time of publication of this document (i.e. for the determination of setting time,
strength, soundness and heat of hydration) have been included in this standard. In addition, work is
being carried out by CEN/TC 51 to identify any additional tests which are needed to specify further
performance characteristics of cement. Until further performance tests are available it is necessary that
the choice of cement, especially the type and/or strength class in relation to the requirements for
durability depending on exposure class and type of construction in which it is incorporated, follows the
appropriate standards and/or regulations for concrete, mortar, grout etc. valid in the place of use.
The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent concerning Portland limestone calcined
clay cement given in Clause 4 as a possible CEM II/C-M cement and which is claimed to be relevant for
the following clauses of this document: Clause 1 and Clause 4.
CEN takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured CEN that he/she is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this
respect, the statement of the holder of this patent right is registered with CEN. Information may be
obtained from:
Aalborg Portland A/S, 9220 Aalborg Ost, Denmark.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those identified above. CEN shall not be held responsible for identifying any or
all such patent rights.
