Putz- und Mauerbinder - Teil 1: Zusammensetzung, Anforderungen und Konformitätskriterien
Diese Europäische Norm legt die Definition und die Zusammensetzung von Putz- und Mauerbindern, die üblicherweise in Europa für Putz- und Mauerarbeiten verwendet werden, fest. Sie enthält physikalische, mechanische und chemische Anforderungen und definiert Festigkeitsklassen. Darüber hinaus enthält EN 413-1 die Konformitäts¬kriterien und die damit verbundenen Regeln sowie notwendige Anforderungen an die Dauerhaftigkeit.
ANMERKUNG In der Regel sind die in EN 413-1, EN 998-1 und EN 998-2 enthaltenen Angaben für die übliche Anwendung ausreichend. In besonderen Fällen kann jedoch ein Austausch von zusätzlichen Informationen zwischen dem Hersteller von Putz- und Mauerbindern und dem Abnehmer hilfreich sein. Die Einzelheiten eines solchen Informationsaustauschs sind nicht Gegenstand von EN 413-1; sie sollten in Übereinstimmung mit nationalen Normen oder mit anderen Regelungen festgelegt werden oder können zwischen den betreffenden Parteien vereinbart werden.

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 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

FprEN 413-1:2010 (E) 3 Foreword This document (FprEN 413-1:2010) has been prepared by Technical Committee CEN/TC 51 "Cement and building limes", the secretariat of which is held by NBN. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede 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 SO3 content is increased. 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. kSIST FprEN 413-1:2010
FprEN 413-1:2010 (E) 4 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. kSIST FprEN 413-1:2010
FprEN 413-1:2010 (E) 5 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. kSIST FprEN 413-1:2010
FprEN 413-1:2010 (E) 6 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

FprEN 413-1:2010 (E) 8 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. kSIST FprEN 413-1:2010

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
(35 ± 3) mm using the plunger apparatus as the reference method. The flow table test is the alternative method. The test results shall meet the requirements given in Table 2. kSIST FprEN 413-1:2010

NOTE An air-entraining agent is incorporated into masonry cements to improve their workability and durability. An upper limit is set for air content to maintain good bond strength to masonry units. The water retention limits are specified for all classes of masonry cement to provide a performance suitable for use with high suction masonry units. 5.3.6 Compressive strength The compressive strength when determined in accordance with EN 196-1, at the fixed water/masonry cement ratio of 0,50 shall have the values given in Table 3.

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 Directive 1907/2006 sets limits on water-soluble hexavalent chromium determined in accordance with EN 196-10. kSIST FprEN 413-1:2010
