Tests for mechanical and physical properties of aggregates - Part 6: Determination of particle density and water absorption

This document specifies the reference methods used for type testing and in case of dispute, for the determination of particle density and water absorption of normal weight and lightweight aggregates. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. For convenience, some of these other methods are also described in this document.
The reference methods for normal weight aggregates are:
-   a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for railway ballast which uses Annex B);
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the 4 mm test sieve (Clause 8);
-   a pyknometer method for aggregate particles passing the 4 mm test sieve and retained on the 0,063 mm test sieve (Clause 9).
In Clauses 7, 8 and 9, three different particle density parameters (oven-dried particle density, saturated and surface-dried particle density and apparent particle density) and water absorption are determined after a soaking period of 24 h. In Annex B, the oven-dried particle density parameter is determined after soaking in water to constant mass.
For aggregate particles passing the 31,5 mm test sieve and retained on the 4 mm test sieve, the wire basket method in Clause 7 can be used as an alternative to the pyknometer method in Clause 8.
NOTE 1   The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve.
NOTE 2   The pyknometer method described in Clause 8 can be used as an alternative for aggregates passing the 4 mm sieve and retained on the 2 mm sieve.
The reference methods for lightweight aggregates are:
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the 4 mm test sieve (Annex C). Three different particle density parameters (oven-dried particle density, saturated and surface-dried particle density and apparent particle density) and water absorption are determined after pre-drying and a soaking period of 24 h;
-   a method for aggregate particles passing the 4 mm test sieve, mixed with water and filtered in a Büchner funnel (Annex D). The three particle densities and water absorption are determined using a vacuum in the range of 50 mbar to 100 mbar for at least five minutes.
Three other methods for normal weight aggregates can be used to determine the pre-dried particle density, as specified in normative Annexes A and H:
-   a wire basket method for aggregate particles passing the 63 mm test sieve and retained on the 31,5 mm test sieve (A.3);
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the 0,063 mm test sieve (A.4);
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve, including the 0/0,063 mm size fraction (Annex H).
NOTE 3   If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the pre-dried particle density method as defined in Annex A.
The quick method in normative Annex E can be used in factory production control to determine the apparent particle density of lightweight aggregates.
The method in informative Annex F can be used to determine the particle density and water absorption of aggregates particles passing the 4 mm test sieve.
Data on the density of water at various temperatures is specified in normative Annex G.
Guidance on the significance and use of the various density and water absorption parameters is given in informative Annex I.
Annex J (informative) contains precision data.

Prüfverfahren für mechanische und physikalische Eigenschaften von Gesteinskörnungen - Teil 6: Bestimmung der Rohdichte und der Wasseraufnahme

Dieses Dokument legt das für die Erstprüfung und in Streitfällen anzuwendende Referenzverfahren für die Bestimmung der Rohdichte und der Wasseraufnahme von normalschweren und leichten Gesteinskörnungen fest. Für andere Zwecke, z. B. die werkseigene Produktionskontrolle, können andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang zum Referenzverfahren nachgewiesen wurde. Der Einfachheit halber sind einige dieser anderen Verfahren ebenfalls in diesem Dokument beschrieben.
Die Referenzverfahren für normalschwere Gesteinskörnungen sind
-   ein Drahtkorbverfahren für Gesteinskörnungen, die vom 31,5 mm Sieb zurückgehalten werden (Abschnitt 7, außer für Gleisschotter, hier Anhang B verwenden),
-   ein Pyknometer-Verfahren für Gesteinskörnungen, die durch das 31,5 mm Analysensieb hindurchgehen und vom 4 mm Analysensieb zurückgehalten werden (Abschnitt 8) und
-   ein Pyknometer-Verfahren für Gesteinskörnungen, die durch das 4 mm Analysensieb hindurchgehen und vom 0,063 mm Analysensieb zurückgehalten werden (Abschnitt 9).
In Abschnitt 7, Abschnitt 8 und Abschnitt 9 werden drei verschiedene Parameter der Rohdichte (Rohdichte auf ofentrockener Basis, Rohdichte auf wassergesättigter und oberflächentrockener Basis und scheinbare Rohdichte) und die Wasseraufnahme nach einer Eintauchzeit von 24 h bestimmt. In Anhang B wird der Parameter der Rohdichte auf ofentrockener Basis nach dem Eintauchen in Wasser bis zur Massenkonstanz bestimmt.
Für Gesteinskörnungen, die durch das 31,5 mm Analysensieb hindurchgehen und vom 4 mm Analysensieb zurückgehalten werden, kann das Drahtkorbverfahren aus Abschnitt 7 als Alternative zum Pyknometer-Verfahren aus Abschnitt 8 verwendet werden.
ANMERKUNG 1   Das Drahtkorbverfahren kann auch für einzelne Gesteinskörner angewendet werden, die von einem 63 mm Sieb zurückgehalten werden.
ANMERKUNG 2   Das in Abschnitt 8 beschriebene Pyknometer-Verfahren kann als eine Alternative für Gesteins-körnungen angewendet werden, die durch das 4 mm Sieb hindurchgehen und vom 2 mm Sieb zurückgehalten werden.
Die Referenzverfahren für leichte Gesteinskörnungen sind
-   ein Pyknometer-Verfahren für Gesteinskörnungen, die durch das 31,5 mm Analysensieb hindurchgehen und vom 4 mm Analysensieb zurückgehalten werden (Anhang C). Es werden drei verschiedene Parameter der Rohdichte (Rohdichte auf ofentrockener Basis, Rohdichte auf wassergesättigter und oberflächentrockener Basis und scheinbare Rohdichte) und die Wasseraufnahme nach dem Vortrocknen und einer Eintauchzeit von 24 h bestimmt;
-   ein Verfahren für Gesteinskörnungen, die durch das 4 mm Analysensieb hindurchgehen, mit Wasser vermischt und in einem Büchner-Trichter gefiltert werden (Anhang D). Die drei Rohdichten und die Wasseraufnahme werden unter einem Vakuum im Bereich von 50 mbar bis 100 mbar über mindestens fünf Minuten bestimmt.
Zur Bestimmung der Trockenrohdichte von normalschweren Gesteinskörnungen können auch drei andere Verfahren angewendet werden, die im normativen Anhang A und im normativen Anhang H festgelegt sind:
-   ein Drahtkorbverfahren für Gesteinskörnungen, die durch das 63 mm Analysensieb hindurchgehen und vom 31,5 mm Analysensieb zurückgehalten werden (A.3);
-   ein Pyknometer-Verfahren für Gesteinskörnungen, die durch das 31,5 mm Analysensieb hindurchgehen und vom 0,063 mm Analysensieb zurückgehalten werden (A.4);
-   ein Pyknometer-Verfahren für Gesteinskörnungen, die durch das 31,5 mm Analysensieb hindurch-gehen, einschließlich der Kornklasse 0/0,063 mm (Anhang H).
ANMERKUNG 3   Wenn die Wasseraufnahme geringer als etwa 1,5 % ist, kann die scheinbare Rohdichte durch Verwendung des Verfahrens der Trockenrohdichte, wie in Anhang A definiert, abgeschätzt werden.
Das Schnellverfahren im normativen Anhang E kann in der werkseigenen Produktionskontrolle zur Bestimmung der scheinbaren Rohdichte von leichten Gesteinskörnungen angewendet werden.
Das Verfahren im informativen Anhang F

Essais pour déterminer les caractéristiques mécaniques et physiques des granulats - Partie 6 : Détermination de la masse volumique et du coefficient d'absorption d'eau

Le présent document spécifie les méthodes de référence utilisées pour les essais de type et en cas de contestation pour la détermination de la masse volumique et du coefficient d'absorption d'eau de granulats courants et légers. D'autres méthodes peuvent être utilisées à d'autres fins, telles que la maîtrise de la production des granulats, à condition que des corrélations appropriées avec la méthode de référence aient été établies. Certaines de ces autres méthodes sont également décrites dans le présent document à des fins pratiques.
Les méthodes de référence pour des granulats courants sont :
-   la méthode du panier en treillis pour les granulats refusés au tamis de 31,5 mm (Article 7, excepté pour les ballasts de voies ferrées qui utilisent l’Annexe B) ;
-   la méthode au pycnomètre pour les granulats passant au tamis de 31,5 mm et refusés au tamis de 4 mm (Article 8) ;
-   la méthode au pycnomètre pour les granulats passant au tamis de 4 mm et refusés au tamis de 0,063 mm (Article 9).
Dans les Articles 7, 8 et 9, trois paramètres différents de masse volumique (masse volumique réelle après séchage à l’étuve, masse volumique réelle saturée surface sèche et masse volumique absolue) et le coefficient d’absorption d’eau sont déterminés après immersion pendant 24 heures. Dans l’Annexe B, le paramètre de masse volumique réelle après séchage à l’étuve est déterminé après immersion dans l’eau jusqu’à masse constante.
Pour les granulats passant au tamis de 31,5 mm et refusés au tamis de 4 mm, la méthode du panier en treillis de l’article 7 peut remplacer la méthode au pycnomètre dans l’article 8.
NOTE 1   La méthode du panier en treillis peut également être utilisée pour des particules isolées refusées au tamis de 63 mm.
NOTE 2   La méthode au pycnomètre décrite à l’Article 8 peut également être utilisée pour les granulats passant au tamis de 4 mm et refusés au tamis de 2 mm.
Les méthodes de référence pour les granulats légers sont :
-   la méthode au pycnomètre pour des granulats passant au tamis de 31,5 mm et refusés au tamis de 4 mm (Annexe C). Trois types de masses volumiques (masse volumique réelle séchée à l’étuve, masse volumique réelle saturée surface sèche et masse volumique absolue) et le coefficient d’absorption d’eau sont déterminés après pré-séchage puis immersion dans l’eau pendant 24 h ;
-   la méthode pour les granulats passant le tamis d'essai de 4 mm, mélangées à de l'eau et filtrées dans un entonnoir Büchner (annexe D). Les trois densités de particules et le coefficient d'absorption d'eau sont déterminés en utilisant un vide dans la gamme de 50 mbar à 100 mbar pendant au moins cinq minutes.
Trois autres méthodes peuvent être utilisées avec des granulats courants en vue de déterminer la masse volumique réelle pré-séchée, comme spécifié dans les annexes normatives A et H :
-   la méthode du panier en treillis pour des granulats passant au tamis de 63 mm et refusés au tamis de 31,5 mm (Article A.3) ;
-   la méthode au pycnomètre pour des granulats passant au tamis de 31,5 mm et refusés au tamis de 0,063 mm (Article A.4) ;
-   la méthode au pycnomètre pour des granulats passant au tamis de 31,5 mm, y compris la classe granulaire 0/0,063 mm (Annexe H).
NOTE 3   Si le coefficient d’absorption d’eau est inférieur à environ 1,5 %, la masse volumique absolue peut être déterminée en utilisant la méthode pour la masse volumique réelle pré-séchée définie à l’Annexe A.
La méthode rapide décrite dans l’Annexe normative E peut être utilisée pour la maîtrise de la production des granulats afin de déterminer la masse volumique absolue des granulats légers.
La méthode décrite à l'annexe informative F peut être utilisée pour déterminer la masse volumique et le coefficient d'absorption d'eau des granulats qui passent le tamis de 4 mm.

Preskusi mehanskih in fizikalnih lastnosti agregatov - 6. del: Določevanje prostorninske mase zrn in vpijanja vode

Ta dokument določa referenčne metode, ki se uporabljajo za tipsko preskušanje in v primeru spora za določevanje prostorninske mase zrn in vpijanja vode agregatov z običajno težo in lahkih agregatov. Za druge namene, na primer za kontrolo proizvodnje v obratu, je mogoče uporabiti druge metode, če obstaja primerna delovna povezava z referenčno metodo. Za lažjo uporabo so v tem dokumentu opisane tudi nekatere druge metode.
Referenčne metode za agregate z običajno težo so:
–   metoda z žično košaro za zrna agregatov, ki ostanejo na situ 31,5 mm (točka 7, razen za grede železniških prog, za katere se uporablja dodatek B);
–   metoda s piknometrom za zrna agregatov, ki gredo skozi preskusno sito 31,5 mm in ostanejo na preskusnem situ 4 mm (točka 8);
–   metoda s piknometrom za zrna agregatov, ki gredo skozi preskusno sito 4 mm in ostanejo na preskusnem situ 0,063 mm (točka 9).
V točkah 7, 8 in 9 so določeni trije različni parametri prostorninske mase zrn (prostorninska masa sušenih zrn, prostorninska masa zrn z nasičeno suho površino in dejanska prostorninska masa zrn) in vpijanje vode po 24-urnem namakanju. V dodatku B je določen parameter prostorninske mase sušenih zrn po namakanju v vodi do stalne mase.
Za zrna agregatov, ki gredo skozi preskusno sito 31,5 mm in ostanejo na preskusnem situ 4 mm, je mogoče namesto metode s piknometrom iz točke 8 uporabiti metodo z žično košaro iz točke 7.
OPOMBA 1:   Metodo z žično košaro je mogoče uporabiti tudi za posamezna zrna agregatov, ki ostanejo na situ 63 mm.
OPOMBA 2:   Metodo s piknometrom, ki je opisana v točki 8, je mogoče uporabiti kot alternativo za agregate, ki gredo skozi sito 4 mm in ostanejo na situ 2 mm.
Referenčne metode za lahke agregate so:
–   metoda s piknometrom za zrna agregatov, ki gredo skozi preskusno sito 31,5 mm in ostanejo na preskusnem situ 4 mm (dodatek C). Trije različni parametri prostorninske mase zrn (prostorninska masa sušenih zrn, prostorninska masa zrn z nasičeno suho površino in dejanska prostorninska masa zrn) in vpijanje vode se določijo po predhodnem sušenju in 24-urnem namakanju;
–   metoda za zrna agregatov, ki gredo skozi preskusno sito 4 mm, pri čemer se zmešajo z vodo in filtrirajo skozi Büchnerjev lijak (dodatek D). Tri prostorninske mase zrn in vpijanje vode se določijo z uporabo vakuuma v razponu od 50 do 100 mbar za najmanj pet minut.
Za določanje prostorninske mase predhodno sušenih zrn agregatov z običajno težo se lahko uporabijo tri druge metode, ki so določene v normativnih dodatkih A in H:
–   metoda z žično košaro za zrna agregatov, ki gredo skozi preskusno sito 63 mm in ostanejo na preskusnem situ 31,5 mm (A.3);
–   metoda s piknometrom za zrna agregatov, ki gredo skozi preskusno sito 31,5 mm in ostanejo na preskusnem situ 0,063 mm (A.4);
–   metoda s piknometrom za zrna agregatov, ki gredo skozi preskusno sito 31,5 mm, vključno z deležem velikosti 0/0,063 (dodatek H).
OPOMBA 3:   Če je vpijanje vode manjše od 1,5 %, je mogoče dejansko prostorninsko maso zrn oceniti z uporabo metode za prostorninsko maso predhodno sušenih zrn, kot je določeno v dodatku A.
Hitra metoda v normativnem dodatku E se lahko uporabi pri kontroli proizvodnje v obratu za določevanje dejanske prostorninske mase zrn lahkih agregatov.
Metoda v informativnem dodatku F se lahko uporabi za določevanje prostorninske mase in vpijanja vode pri zrnih agregatov, ki gredo skozi preskusno sito 4 mm.
Podatki o gostoti vode pri različnih temperaturah so navedeni v normativnem dodatku G.
Napotki o pomembnosti in uporabi različnih parametrov prostorninske mase in vpijanja vode so podani v informativnem dodatku I.
Dodatek J (informativni) vsebuje podatke o natančnosti.

European foreword
This document (EN 1097-6:2022) has been prepared by Technical Committee CEN/TC 154
“Aggregates”, the secretariat of which is held by BSI.
This document shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by August 2022, and conflicting national standards shall be
withdrawn at the latest by August 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1097-6:2013.
In comparison with the previous edition, the following technical modifications have been made:
a) Normative references has been extended with EN 1097-5 (used in Annex D). EN 932-1 has been
deleted from the clause since sampling is out of the scope, as for other standards;
b) the definitions of laboratory sample and subsample have been added in Clause 3;
c) the glass funnel in 6.4.4 has been deleted since it is part of the pyknometer in 6.5.1. The minimum
volume of the pyknometer in 6.5.1 has been changed from 250 ml to 500 ml. New 6.8 and 6.10
have been added and describe special apparatus referenced in new Annexes D and F;
d) Clause 9 has been extended with an illustration of the surface-dry state assessment using the
cone test;
e) the possibility to remove air from the pyknometer by applying a vacuum has been added in A.4.3;
f) in Annex B, the test portion mass for single aggregates (B.2.2) and the temperature requirement
in B.3 have been clarified. In addition, the time needed for achieving constant mass during
suction has been clarified;
g) the Note in C.1 has been revised to say that the method can also be used for aggregate particles
passing the 4 mm sieve and retained on the 1 mm sieve. Soaking times for the water absorption
determination have been added in C.1. A new paragraph has been added in C.1, saying that for
concrete applications the water absorption of coarse lightweight aggregate shall be determined
in the as-used moisture state instead of the oven-dry state. In C.4, a Note about using vibrating
table as a vibration means has been added. Precision of individual values has been defined in C.5;
h) a new normative Annex D has been designed to determine the particle density and water
absorption of fine lightweight aggregates. Consequently, Annex C has been retitled to only apply
to coarse lightweight aggregates;
i) the title of Annex E has been shorted. The Note in E.1 has been revised to say that the method

1 Scope
This document specifies the reference methods used for type testing and in case of dispute, for the
determination of particle density and water absorption of normal weight and lightweight aggregates.
Other methods can be used for other purposes, such as factory production control, provided that an
appropriate working relationship with the reference method has been established. For convenience,
some of these other methods are also described in this document.
The reference methods for normal weight aggregates are:
— a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for
railway ballast which uses Annex B);
— a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the
4 mm sieve (Clause 8);
— a pyknometer method for aggregate particles passing the 4 mm sieve and retained on the
0,063 mm sieve (Clause 9).
In Clauses 7, 8 and 9, three different particle densities (oven-dried particle density, saturated and
surface-dried particle density and apparent particle density) and water absorption are determined
after a soaking period of 24 h. In Annex B, the oven-dried particle density is determined after soaking
in water to constant mass.
For aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve, the wire basket
method in Clause 7 can be used as an alternative to the pyknometer method in Clause 8.
NOTE 1 The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve.
NOTE 2 The pyknometer method described in Clause 8 can be used as an alternative for aggregates passing
the 4 mm sieve and retained on the 2 mm sieve.
The reference methods for lightweight aggregates are:
— a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the
4 mm sieve (Annex C). Three different particle densities (oven-dried; saturated and surface-
dried; apparent) and water absorption are determined after pre-drying and a soaking period of
24 h;
— a method, using a Büchner funnel, for aggregate particles passing the 4 mm sieve (Annex D). The
three particle densities and water absorption are determined using a vacuum in the range of 50
mbar to 100 mbar for at least five minutes.
Three other methods for normal weight aggregates can be used to determine the pre-dried
particle density, as specified in normative Annexes A and H:
— a wire basket method for aggregate particles passing the 63 mm sieve and retained on the
31,5 mm sieve (A.3);
— a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the
0,063 mm sieve (A.4);
— a pyknometer method for aggregate particles passing the 31,5 mm sieve, including the
0/0,063 mm size fraction (Annex H).
NOTE 3 If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the
pre-dried particle density method as defined in Annex A.

1 Scope
This document specifies the reference methods used for type testing and in case of dispute, for the
determination of particle density and water absorption of normal weight and lightweight aggregates.
Other methods can be used for other purposes, such as factory production control, provided that an
appropriate working relationship with the reference method has been established. For convenience,
some of these other methods are also described in this document.
The reference methods for normal weight aggregates are:
— a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for
railway ballast which uses Annex B);
— a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the
4 mm test sieve (Clause 8);
— a pyknometer method for aggregate particles passing the 4 mm test sieve and retained on the
0,063 mm test sieve (Clause 9).
In Clauses 7, 8 and 9, three different particle density parameters (oven-dried particle density,
saturated and surface-dried particle density and apparent particle density) and water absorption are
determined after a soaking period of 24 h. In Annex B, the oven-dried particle density parameter is
determined after soaking in water to constant mass.
For aggregate particles passing the 31,5 mm test sieve and retained on the 4 mm test sieve, the wire
basket method in Clause 7 can be used as an alternative to the pyknometer method in Clause 8.
NOTE 1 The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve.

the 4 mm sieve and retained on the 2 mm sieve.
The reference methods for lightweight aggregates are:
— a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the
4 mm test sieve (Annex C). Three different particle density parameters (oven-dried particle
density, saturated and surface-dried particle density and apparent particle density) and water
absorption are determined after pre-drying and a soaking period of 24 h;
— a method for aggregate particles passing the 4 mm test sieve, mixed with water and filtered in a
Büchner funnel (Annex D). The three particle densities and water absorption are determined
using a vacuum in the range of 50 mbar to 100 mbar for at least five minutes.
Three other methods for normal weight aggregates can be used to determine the pre-dried
particle density, as specified in normative Annexes A and H:
— a wire basket method for aggregate particles passing the 63 mm test sieve and retained on the
31,5 mm test sieve (A.3);
— a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the
0,063 mm test sieve (A.4);
— a pyknometer method for aggregate particles passing the 31,5 mm test sieve, including the
0/0,063 mm size fraction (Annex H).
NOTE 3 If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the
pre-dried particle density method as defined in Annex A.
