Methods of testing cement - Part 3: Determination of setting times and soundness
This document specifies the methods for determining standard consistence, setting times and soundness of cements.
The method applies to common cements and to other cements and materials, the standards for which call up this method. It may not apply to other cement types that have, for example, a very short initial setting time. The method is used for assessing whether the setting time and soundness of a cement is in conformity with its specification.
This document describes the reference methods and allows the use of alternative procedures and equipment, as indicated in notes, provided that they have been calibrated against the reference methods. In the event of a dispute, only the reference equipment and procedures are used.
Prüfverfahren für Zement - Teil 3: Bestimmung der Erstarrungszeiten und der Raumbeständigkeit
Dieses Dokument legt die Verfahren zur Bestimmung der Normsteife, der Erstarrungszeiten und der
Raumbeständigkeit von Zement fest.
Das Verfahren gilt für Normalzemente; ferner gilt sie für andere Zemente und Baustoffe, wenn in den
entsprechenden Normen auf das Verfahren verwiesen wird. Unter Umständen gilt das Verfahren nicht für
Zementarten, bei denen beispielsweise der Erstarrungsbeginn sehr rasch einsetzt. Das Verfahren wird
angewendet, um beurteilen zu können, ob Zemente die gestellten Anforderungen hinsichtlich der
Erstarrungszeiten und der Raumbeständigkeit erfüllen.
Dieses Dokument beschreibt die Referenzverfahren; andere Verfahren und Geräte ? sofern in Anmerkungen
darauf hingewiesen ist ? dürfen angewendet werden, wenn sie nachweislich zu den gleichen Prüfergebnissen
führen wie die vorgeschriebenen Verfahren und Geräte. Im Streitfall sind die Referenzgeräte und das
Referenzverfahren maßgebend.
Méthodes d'essais des ciments - Partie 3: Détermination du temps de prise et de la stabilité
Le présent document spécifie les méthodes permettant de déterminer la consistance normalisée, les temps de prise et la stabilité des ciments.
La méthode s’applique aux ciments courants et a d’autres ciments et matériaux, pour lesquels les normes prescrivent ces méthodes. Elle ne doit pas s’appliquer aux autres types de ciments, qui ont, par exemple, un temps de début de prise tres court. La méthode est utilisée pour juger si le temps de prise et la stabilité d’un ciment sont conformes a sa spécification.
Le présent document décrit les méthodes de référence et, comme indiqué dans les notes, autorise l'utilisation de variantes pour les modes opératoires et l’équipement, a condition que ces variantes aient été étalonnées par rapport aux méthodes de référence. En cas de litige, on doit utiliser seulement l’équipement et les modes opératoires de référence.

1 Scope
This document specifies the methods for determining standard consistence, setting times and
soundness of cements.
The method applies to common cements and to other cements and materials, the standards for which
call up this method. It may not apply to other cement types that have, for example, a very short initial
setting time. The method is used for assessing whether the setting time and soundness of a cement is
in conformity with its specification.
This document describes the reference methods and allows the use of alternative procedures and
equipment, as indicated in notes, provided that they have been calibrated against the reference
methods. In the event of a dispute, only the reference equipment and procedures are used.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 196-1, Methods of testing cement — Part 1: Determination of strength
3 Principles
Cement paste of standard consistence has a specified resistance to penetration by a standard
plunger. The water required for such a paste is determined by trial penetrations of pastes with
different water contents.
The setting time is determined by observing the penetration of a needle into cement paste of standard
consistence until it reaches a specified value.
The soundness is determined by observing the volume expansion of cement paste of standard
consistence as indicated by the relative movement of two needles.
4 Laboratory, equipment and materials
4.1 Laboratory
The laboratory in which specimens are prepared and tested shall be maintained at a temperature of
(20 ± 2) °C and a relative humidity of not less than 50 %.
The temperature and relative humidity of the air in the laboratory and the temperature of the water in
the storage containers shall be recorded at least once per day during working hours.
Cement, water and apparatus used to make and test specimens shall be at a temperature of
(20 ± 2) °C.
Where temperature ranges are given, the target temperature at which the controls are set shall be the
middle value of the range.

4.2 Equipment and materials
4.2.1 General requirements
The tolerances shown in Figures 1 and 2 are important for correct operation of the equipment in the
testing procedure. When regular control measurements show that the tolerances are not met, the
equipment shall be rejected, adjusted or repaired. Records of control measurements shall be kept.
Acceptance measurements on new equipment shall cover mass, volume, and dimensions to the
extent that these are indicated in this document paying particular attention to those critical dimensions
for which tolerances are specified.
In those cases where the material of the equipment can influence the results, the material is specified
and shall be used.
The approximate dimensions shown in the figures are provided as guidance to equipment
manufacturers or operators. Dimensions which include tolerances are obligatory.
4.2.2 Balance, capable of weighing to an accuracy of ± 1 g.
4.2.3 Graduated cylinder or burette, capable of dispensing to an accuracy of ± 1 ml.
4.2.4 Mixer, conforming to EN 196-1.
NOTE A more homogeneous paste is produced at the lower limit of tolerance for the clearance between the
blade and the bowl.
4.2.5 Water, distilled or deionized water shall be used for making the specimens. Drinking water
may be used for storing and boiling specimens.
4.2.6 Timer, capable of measuring to an accuracy of ± 1 s.
4.2.7 Ruler, capable of measuring to an accuracy of ± 0,5 mm.
5 Standard consistence test
5.1 Apparatus
Use the manual Vicat apparatus as shown in Figure 1 a) and 1 b) with the plunger shown in
Figure 1 c). The plunger shall be of non-corrodible metal in the form of a right cylinder of at least
45 mm effective length and of (10,00 ± 0,05) mm diameter. The total mass of moving parts shall be
(300 ± 1) g. Their movement shall be truly vertical and without appreciable friction, and their axis shall
coincide with that of the plunger.
The Vicat mould (see Figure 1 a)) to contain the paste under test shall be of hard rubber, plastics or
brass. It shall be of cylindrical or preferably truncated conical form (40,0 ± 0,2) mm deep and shall
have an internal diameter of (75 ± 10) mm. It shall be adequately rigid and shall be provided with a
base-plate larger than the mould and at least 2,5 mm thick, constructed of impermeable material
resistant to attack by cement paste, e.g. plane glass.
NOTE 1 Moulds of other metal may be used provided that they are of the specified depth and that their use
has been calibrated against the specified mould.
NOTE 2 It is recommended that a laboratory uses base plates of equal thickness in order that the scale of the
Vicat apparatus has only to be adjusted once for several determinations.

5.2 Procedure
5.2.1 Mixing the cement paste
Weigh, to an accuracy of ±1 g, by means of the balance (4.2.2), 500 g of cement and a quantity of

it shall be dispensed to an accuracy of ± 1 ml. Mix each batch of paste mechanically using the mixer
(4.2.4). The t
