Overview

EN 413-1:2011 - Masonry cement: Part 1: Composition, specifications and conformity criteria is the CEN European standard that defines what masonry cement is, what it may contain, and the performance and conformity requirements for masonry cements commonly used in Europe for producing mortar for bricklaying, blocklaying, rendering and plastering. The standard establishes compositional limits, physical/mechanical/chemical requirements, strength classes and durability guidance, and sets out conformity assessment rules for manufacturers.

Key topics and requirements

• Definition & composition: Masonry cement is a factory-made finely powdered hydraulic binder relying mainly on Portland cement clinker, with permitted inorganic constituents (natural minerals, clinker-derived materials, hydrated/hydraulic limes) and approved additives. Small amounts of calcium sulfate are used to control setting. Organic pigments are not permitted; carbon black is discouraged because it affects air entrainment.
• Strength classes: Designation uses the prefix MC with strength classes (MC 5, MC 12,5 and MC 22,5). An air‑entrained variant is available (e.g., MC 22,5 with air‑entraining agent).
• Physical & mechanical properties: Requirements include fineness (sieve residue), initial and final setting times, soundness, fresh mortar characteristics (workability/cohesivity) and compressive strength measured on standard mortars.
• Chemical & durability requirements: Chemical limits and durability considerations (e.g., resistance to aggressive environments) are specified. Annex A addresses water‑soluble hexavalent chromium considerations.
• Conformity & testing: The standard defines manufacturer autocontrol testing, sampling plans, statistical conformity criteria (percentile-based characteristic values and acceptance probabilities), single-result limits and required testing frequencies. Reference test methods are given in EN 413-2 and relevant parts of EN 196.

Practical applications & users

• Who uses EN 413-1:2011
  • Masonry cement producers (composition, production control and factory testing)
  • Specifiers, architects and engineers (selection of cement class for masonry works)
  • Masonry contractors and plasterers (ensuring mortar performance and durability)
  • Test laboratories and conformity assessors (statistical evaluation, sample testing)
  • Regulators and procurement bodies (harmonised product specifications)
• Why it matters
  • Ensures consistent mortar performance (strength, workability, durability) for bricklaying, blockwork and rendering
  • Helps select the correct masonry cement class for environmental exposure and structural requirements
  • Provides the conformity framework used for factory production control and CE-marking procedures

Related standards

• EN 413-2 - Masonry cement: Test methods (reference for laboratory procedures)
• EN 196 (Parts 1–7) - Methods of testing cement (strength, chemical analysis, setting, fineness, sampling)
• EN 998-1 / EN 998-2 - Mortar specifications for masonry and rendering (selection guidance)
• EN 197-1, EN 459-1, EN 12878 - Related cement, lime and pigment standards
• EN 1996-1-1 (Eurocode 6) - Design rules for masonry where masonry cement selection affects durability

Practical takeaway: Use EN 413-1:2011 to specify and verify masonry cement composition, performance and conformity so mortar used in masonry and rendering meets required strength and durability for the intended application.

This document supersedes EN 413-1:2004.
The European Standard, EN 413, “Masonry cement”, consists of the following parts:
Part 1: Composition, specifications and conformity criteria;
Part 2: Test methods.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
EN 413-1 has been prepared to provide a range of materials from which users of EN 998-1, EN 998-2
and EN 1996-1-1 (Eurocode 6) can select with confidence to achieve the level of strength and
durability required of masonry and rendering.
The main changes from EN 413-1:2004 are as follows:
- introduction of a class MC 22,5 (air-entrained) cement;
- removal of references to EN 459-2 for compressive strength testing;
- the upper limit for SO content is increased.
According to the CEN/CENELEC Internal Regulations, the national standards organizations 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,

Introduction
Masonry cement should be defined and specified precisely with sufficiently stringent requirements to
satisfy those who are responsible for the design and construction of buildings and other structures for
maximum safety and durability.
This European Standard is a carefully balanced document that has been thoroughly discussed, taking
into account the need to provide clear definitions and specifications and to arrive at a usable standard.
The requirements of this European Standard are, where appropriate, based on the results from tests on
masonry cement in accordance with EN 196 'Methods of testing cement'. Strength is measured on a
standard mortar prepared in accordance with EN 196-1 with a fixed water/cement ratio and compacted
using the equipment described in EN 196-1. However, some additional tests have been found necessary
and these tests are described in EN 413-2.
CEN/TC 51 recognises the importance of workability (cohesivity at standard consistence) of mortars
prepared from masonry cements. A test method is available in CR 13933, and in which results of a test
programme are also given. This test method was not found valid for standard requirement purposes due
to its lack of reproducibility, however it provides valuable information for the manufacturers and users on
the property in use of masonry cements.
The properties of bond and durability (resistance to frost and/or chemical attack) of mortars are very
important and appropriate mortar tests are being developed by CEN/TC 125, Masonry. In many
applications, particularly in severe environmental conditions, the choice of the type/class of masonry
cement from EN 413-1 can influence the durability of mortar, e.g. in respect of frost and chemical
resistance.
1 Scope
This European Standard specifies the definition and composition of masonry cements as commonly used
in Europe for the production of mortar for bricklaying and blocklaying and for rendering and plastering. It
includes physical, mechanical and chemical requirements and defines strength classes. EN 413-1 also
states the conformity criteria and the related rules. Necessary durability requirements are also given.
NOTE For normal applications the information given in EN 413-1, in EN 998-1 and in EN 998-2 is generally
sufficient. However, in special cases, an exchange of additional information between the masonry cement
producer and user can be helpful. The details of such an exchange are not within the scope of EN 413-1 but
should be dealt with in accordance with national standards or other regulations or can be agreed between the
parties concerned.

4 Notation
Masonry cement is designated by the term 'MC'.
There are three strength classes of masonry cement, 5, 12,5 and 22,5.
The term 'X' designates masonry cements in which an air entraining agent is not incorporated.
5 Requirements
5.1 General
The physical, mechanical and chemical properties of masonry cements shall be measured by the test
methods described in EN 413-2 and in the relevant parts of EN 196. These European Standards give
alternative test methods for some properties but in the event of a dispute only the reference methods
shall be used. Where allowed in the relevant part of EN 196, different methods may be used provided
they give correlated and equivalent values to those obtained using the reference method.
The CEN Standard sand (see EN 196-1) used to make the mortars for the tests required by 5.3.5 and
5.3.6 shall have a silica content (as quartz) of not less than 93 %.
NOTE EN 196-1 permits the use of CEN Standard sands that have been assessed against the CEN
Reference sand in respect of their strength characteristics. According to this standard the CEN Standard sand is
used in mortar for tests other than that for strength. These tests have only been evaluated using CEN Standard
sand based essentially on silica.
All requirements are specified as characteristic values. They serve to define the performance level
and classification of the masonry cements.
5.2 Constituents and composition
Masonry cement shall comprise Portland cement clinker, inorganic constituents and where
appropriate additive(s) as given in Table 1. Calcium sulfate is added in small quantities to the other
constituents of masonry cement during its manufacture to control setting.
The inorganic constituents of masonry cements conforming to EN 413-1 shall be materials selected
from:
 natural mineral materials;
 mineral materials used for or derived from the clinker production process;
 hydrated and/or hydraulic building limes conforming to EN 459-1;
 constituents specified in EN 197-1;
 inorganic pigments (except those containing carbon black) conforming to EN 12878.
NOTE Carbon black has a detrimental effect upon the air entrainment.
Additives shall not promote corrosion of embedded metal such as reinforcement and wall ties or
impair the properties, including behaviour in fire, of the mortar made from the masonry cement.
Organic pigments are not permitted.

The quantity of organic additives on a dry basis shall not exceed 0,5 % by mass of the masonry cement.

The manufacturing process and its control shall ensure that the composition of masonry cement is kept
within the limits fixed in EN 413-1. Masonry cements consist ultimately of individual small grains of
different materials and are statistically homogeneous in composition resulting from quality assured
production and material handling processes.
A high degree of uniformity in all masonry cement properties shall be obtained through mass production
processes, in particular, adequate grinding and homogenization. Qualified and skilled personnel and the
facilities to test, evaluate and adjust product quality are indispensable for producing masonry cement in
accordance with this European Standard.
5.3 Physical and mechanical requirements
5.3.1 Fineness (sieve residue)
The residue on a 90 µm sieve shall be not more than 15 % by mass when determined in accordance
with EN 196-6.
5.3.2 Initial setting time
The initial setting time shall be not less than 60 min when determined in accordance with EN 413-2.
5.3.3 Final setting time
Where the initial setting time is less than 6 h, there is no requirement for final setting time. Where the
initial setting time is 6 h or more, the final setting time shall be not more than 15 h when determined in
accordance with EN 413-2.
5.3.4 Soundness
The expansion shall be not more than 10 mm when determined in accordance with EN 196-3.
5.3.5 Fresh mortar requirements
The properties of air content and water retention of fresh mortar shall be measured in accordance with
EN 413-2, on a mortar of standard consistence that shall have a value of penetration of

Should it not be possible to remove the prisms from the moulds after 24 h, it is permitted to remove
them at 48 h. Where the prisms are demoulded at 48 h this shall be recorded.
EN 196-1 gives repeatability and reproducibility values for 28 day strength. On account of their lower
strengths, values of 4 % and 8 % respectively are appropriate for masonry cements conforming to this
European Standard.
5.4 Chemical requirements
The properties of the masonry cement shall conform to the requirements given in Table 4 when
determined by the method indicated in this table.
NOTE The REACH Regulation 1907/2006 sets limits on water-soluble hexavalent chromium determined in
accordance with EN 196-10.
