Part 1: Composition, specifications and conformity criteria
This European Standard specifies the definition and composition of masonry cements as commonly used in Europe for the production of mortar for brick laying and block laying 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.

For the purposes of this document, the following terms and definitions apply.
3.1 masonry cement
factory made finely powdered hydraulic binder which relies essentially upon the presence of Portland cement clinker to develop strength. When mixed with sand and water only and without the addition of further materials it produces a workable mortar suitable for use in rendering, plastering and masonry work
3.2 additives
constituents which are added to improve the manufacture or the properties of the masonry cement, e.g.grinding aids, air-entraining agents
3.3 autocontrol testing
continual testing by the manufacturer, of masonry cement spot samples taken at the point(s) of release from the factory/depot
3.4 control period
period of production and dispatch identified for the evaluation of the autocontrol test results
3.5 3.6 3.7 3.8 3.9 3.10 4 3.5 characteristic value
value of a required property outside of which lies a specified percentage, the percentile P k , of all the values of the population
3.6 specified characteristic value
characteristic value of a mechanical, physical or chemical property which in the case of an upper limit is not to be exceeded or, in the case of a lower limit is, as a minimum, to be reached
3.7 single result limit value
value of a mechanical, physical or chemical property which, for any single test result as in the case of an upper limit is not to be exceeded or, in the case of a lower limit is, as a minimum, to be reached
3.8 allowable probability of acceptance CR for a given sampling plan, the allowed probability of acceptance of masonry cement with a characteristic value outside the specified characteristic value
3.9 sampling plan
specific plan which states the (statistical) sample size(s) to be used, the percentile P k and the allowable probability of acceptance CR
3.10 spot sample
sample taken at the same time and from one and the same place, relating to the intended tests. It can be obtained by combining one or more immediately consecutive increments (see EN 196-7)
Masonry cement is designated by the term ' 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.
5.1 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 Standardsand 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 whereapprop- riate 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 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 ofdifferent 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 inaccordance with this European Standard.
a The quantity of organic additives on a drybasis shall not exceed 0,5 % by mass of the masonry cement.
5.3 5.3.1 5.3 Physical and mechanical requirements
5.3.1 Fineness (sieve residue)
The residue on a 90 pm sieve shall be not more than 15 % by mass when determined in accordance with EN 196-6.
5.3.2 5.3.3 5.3.4 5.3.5 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 inaccordance 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 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. MC 12,5 > 8 MC 22,5 X <6 a >75 a 5.3.6 5.3.6 Compressive strength
The compressive strength when determined in accordance with EN 196-1, at the fixed water/ma- sonry cement ratio of 0,50 shall have the values 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. Table 3 - Compressive strength requirements given as characteristic values
MC 22,5 X > 10 >22,5 <42,5 a
5.4 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.
