Foreword
This European Standard (EN 413-2:2005) has been prepared by Technical Committee CEN/TC 51
“Cement and building limes”, the secretariat of which is held by IBN.
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 December 2005, and conflicting national standards
shall be withdrawn at the latest by December 2005.
This European Standard supersedes EN 413-2:1994.
EN 413 Masonry cement consists of the following Parts.
Part 1: Composition, specifications and conformity criteria
Part 2: Test methods
The main differences between this European Standard and EN 413-2:1994 are:
Exclusion of workability (cohesivity).
Introduction of an optional setting time procedure using the specimen storage conditions (in air)
that were previously specified in EN 196-3:1994. This is necessary because the (under water)
method specified in EN 196-3:2005, is not suitable for some masonry cements which have low
clinker contents.
Diameter of filter paper used in the water retention test increased from 100 mm to the more
readily available 110 mm size.
Specification introduced for non-woven tissue to be used in the water absorption test.
Weighing precision in water content test increased from 1 g to 0,1 g.
Improved description of procedure for filling of air content test apparatus.
Introduction of precision statements for determination of mortar standard consistency, water
retention and air content.
Clarification of requirements for retesting if mortar flow does not lie within the required range.
Clarification of requirements for retesting if pairs of results for water retention or air content differ
by more than twice the standard deviation of repeatability.
Clarification of calibration procedures for flow table and air content apparatus.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,
Spain, Sweden, Switzerland and United Kingdom.

3.4 Number of tests
Where the test is one of a series subject to statistical control, determination of each property by a
single test shall be the minimum required.
Where the test is not part of a series subject to statistical control, two tests shall be performed to
determine each property.
4 Determination of setting time
4.1 General
The setting time is determined by observing the penetration of a needle into a cement paste of
standard consistence until it reaches a specified value.
The setting time is determined in accordance with either method A (4.2) or method B (4.3).
Method B is the reference method.
4.2 Method A
The setting time is determined in accordance with EN 196-3.
NOTE Experience has shown that the method specified in EN 196-3, in which the specimens are tested
under water, is not suitable for some masonry cements which have low clinker contents.
4.3 Method B
4.3.1 Test principle
The equipment used and the specimen preparation procedures are as described in EN 196-3 but with
the additional requirement for a room or a humidity cabinet of adequate size and maintained at (20 ±
1) °C and not less than 90 % relative humidity.
4.3.2 Initial setting time procedure
Calibrate the Vicat apparatus with the needle, attached in advance of the test, by lowering the needle
to rest on the base-plate to be used and adjusting the pointer to read zero on the scale. Raise the
needle to the stand-by position. Fill a Vicat mould in accordance with 5.2.2 of EN 196-3:2005 with
paste of standard consistence mixed in accordance with 5.2.1 of EN 196-3:2005.
Place the filled mould and base-plate in the room or humidity cabinet and after a suitable time,
position the mould, base-plate and container under the needle of the Vicat apparatus. Lower the
needle gently until it is in contact with the paste. Pause in that position for between 1 s and 2 s in
order to avoid initial velocity or forced acceleration of the moving parts. Then release the moving parts
quickly and allow the needle to penetrate vertically into the paste. Read the scale when penetration
has ceased, or 30 s after the release of the needle, whichever is the earlier.
Record the scale reading, which indicates the distance between the end of the needle and the base-
plate, together with the time from zero. Repeat the penetration on the same specimen at conveniently
spaced positions, not less than 8 mm from the rim of the mould or 5mm from each other and at least
10 mm from the last penetration position, at conveniently spaced intervals of time, e.g. at 10 min
intervals. Between penetrations keep the specimen in a room or humidity cabinet. Clean the Vicat
needle immediately after each penetration. Retain the specimen if determination of the final setting
time is to be made.

4.3.3 Report – initial setting time
Report the time measured from zero at which the distance between the needle and the base-plate is
(6 ± 3) mm as the initial setting time of the cement to the nearest 5 min.
If the initial setting time exceeds 6h determine the final setting time.
4.3.4 Final setting time procedure
Invert the filled mould and follow the procedure described in 6.3 of EN 196-3:2005 with the specimen
held in the room or humidity cabinet at controlled humidity rather than under water.
4.3.5 Report – final setting time
Report the time measured from zero at which the needle first penetrates only 0,5 mm into the
specimen as the final setting time of the cement, to the nearest 15 min.
5 Preparation of standard mortar
5.1 Principle
The properties of fresh mortar made with masonry cement are assessed on standard mortar prepared
in accordance with EN 196-1, but with the water content necessary for the standard consistence.
The consistence is measured using the plunger apparatus (see 5.2) as the reference method to
achieve the required value of penetration.
A flow table test (see 5.3) is allowed as an alternative to the plunger test but it is important that the
flow table spread equivalent to the required value of penetration is established, using the same type
of masonry cement as that which is to be tested.
5.2 Consistence of fresh mortar by plunger apparatus (reference method)
5.2.1 Apparatus
The mixer and ancillary equipment shall be as described in EN 196-1.
The plunger apparatus shown in Figure 1 shall conform to the dimensions specified.
The shape of the baseplate (1) shall enable the mortar container (8) to be placed centrally below the
plunger (7). The plunger shall have a hemispherical lower end, be resistant to corrosion and not
attacked by mortar. The total mass of the rod (6) and plunger (7) shall be (90 ± 2) g. A release
mechanism (5) holds the measuring rod in its initial position so that the lower end of the plunger is
(100 ± 0,5) mm above the mortar surface prior to commencing the test (the initial position in 5.2.2).
The tamper (see Figure 2) shall consist of a round rod made of impermeable material with sheet metal
protection and shall weigh (250 ± 15) g.
5.2.2 Procedure
Prepare the mortar according to the procedure described in EN 196-1 except that the water content
shall be that determined to give the consistence required.
Before the start of each test wipe the plunger with a damp cloth.
Fill the container in two layers immediately after completing the mixing procedure. Compact each
layer with 10 light strokes of the tamper.
