Tests for geometrical properties of aggregates - Part 5: Determination of percentage of crushed particles in coarse and all-in natural aggregates
This document specifies the reference method, used for type testing and in case of dispute, for the determination of the percentages of crushed particles, totally crushed particles and totally rounded particles in coarse and all-in natural 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.
NOTE 1 Examples of advanced test methods can be found in the Bibliography.
This document applies to coarse aggregates comprising particles within size fraction 4/63 mm. It does not apply to lightweight aggregates.
NOTE 2 For coarse aggregate between 4 mm and 20 mm the percentages of crushed surfaces are linked to the flow coefficient and can therefore be used in association with the test method specified in EN 933 6.
Clause 7.1 specifies the procedure for test portions consisting of one size fraction and Clause 7.2 specifies the procedure for test portions consisting of two or more size fractions.
Guidance for the estimated mass of various size fractions with about 100 particles is given in informative Annex A.
Examples of application of the test procedure and an example of a test data sheet are given in informative Annexes B and C.
Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 5: Bestimmung des prozentualen Anteils an gebrochenen Körnern in groben Gesteinskörnungen und Gesteinskörnungsgemischen
Dieses Dokument legt das für die Erstprüfung und im Streitfall anzuwendende Referenzverfahren für die Bestimmung des prozentualen Anteils an gebrochenen Körnern, vollständig gebrochenen Körnern und vollständig gerundeten Körnern in groben Gesteinskörnungen und natürlichen Gesteinskörnungsgemischen fest. Für andere Zwecke, speziell im Rahmen der werkseigenen Produktionskontrolle, können andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang mit dem Referenzverfahren nachgewiesen wurde.
ANMERKUNG 1 Beispiele für erweiterte Prüfverfahren können in den Literaturhinweisen gefunden werden.
Das vorliegende Dokument ist anzuwenden für grobe Gesteinskörnungen mit Körnern in der Kornklasse 4/63 mm. Es ist nicht anzuwenden für leichte Gesteinskörnungen.
ANMERKUNG 2 Bei einer groben Gesteinskörnung zwischen 4 mm und 20 mm hängt der Prozentsatz an gebrochenen Oberflächen mit dem Fließkoeffizienten zusammen und kann deshalb als alternatives Prüfverfahren zu dem in EN 933 6 beschriebenen Verfahren angewendet werden.
In 7.1 wird das Verfahren für Messproben, die aus einer Kornklasse bestehen, und in 7.2 das Verfahren für Messproben, die aus zwei oder mehr Kornklassen bestehen, festgelegt.
Leitlinien für die geschätzte Masse unterschiedlicher Kornklassen mit ungefähr 100 Körnern sind im informativen Anhang A aufgeführt.
Beispiele für die Anwendung des Prüfverfahrens und ein Beispiel eines Prüf-Datenblattes werden im informativen Anhang B und im informativen Anhang C aufgeführt.
Essais pour déterminer les caractéristiques géométriques des granulats - Partie 5 : Détermination du pourcentage de surfaces cassées dans les gravillons et graves naturelles
Le présent document spécifie la méthode de référence, utilisée pour les essais de type et en cas de litige, pour la détermination des pourcentages de grains semi-concassés, de grains entièrement concassés et de grains entièrement roulés de gravillons et de graves naturels. D’autres méthodes peuvent être utilisées à d’autres fins, telles que le contrôle de la production en usine, à condition qu’une relation de travail appropriée ait été établie avec la méthode de référence.
NOTE 1 Des exemples de méthodes d’essai avancées sont présentés dans la Bibliographie.
Le présent document s’applique aux gravillons dont la taille est comprise dans la fraction 4/63 mm. Il ne s’applique pas aux granulats légers.
NOTE 2 Pour les gravillons de taille comprise entre 4 mm et 20 mm, les pourcentages de surfaces cassées sont liés au coefficient d’écoulement et peuvent donc être utilisés en association avec la méthode d’essai spécifiée dans l’EN 933-6.
L’article 7.1 spécifie le mode opératoire pour les prises d’essai constituées d’une fraction granulaire et l’article 7.2 spécifie le mode opératoire pour les prises d’essai constituées d’au moins deux fractions granulaires.
Des indications sur la masse estimée de différentes fractions granulaires contenant environ 100 particules sont données dans l’Annexe A informative.
Des exemples d’application du mode opératoire d’essai et un exemple de feuille d’essai sont donnés dans les Annexes B et C informatives.

3.3
constant mass
mass determined after successive weighings at least 1 h apart not differing by more than 0,1 %
Note 1 to entry: In many cases constant mass can be achieved after a test portion has been dried for a pre-
determined period in a specified oven at (110 ± 5) °C. Test laboratories can determine the time required to achieve
constant mass for specific types and sizes of sample dependent upon the drying capacity of the oven used.
3.4
crushed surface
surface of a particle with angular fractured planar faces and often distinct corners and edges
Note 1 to entry: The crushed surface is usually produced by mechanical processing, but it can also consist of the
original surface of a gravel particle, formed by geological action (breaking without any subsequent significant wear
and weathering of the gravel particle).

totally crushed particle
particle with more than 90 % of its surface crushed (tc)

3.8
totally rounded particle
particle with more than 90 % of its surface rounded (tr)
4 Principle
The test consists of sorting by hand a coarse test portion of natural aggregates into crushed particles,
totally crushed particles and totally rounded particles.
The masses of crushed particles, totally crushed particles and totally rounded particles are determined
and expressed as percentages of the test portion mass.

글 제목: EN 933-5:2022 - 총제철 및 거짓둥근 입자의 비율 결정을 위한 암석 집합물의 기하학적 특성 검사 - 제5부 기사 내용: 이 문서는 거친 암석 집합물과 종합 암석 집합물에서 총제철 입자, 완전히 제철 입자 및 완전히 둥근 입자의 비율을 결정하기 위한 참조 방법을 규정합니다. 기타 용도(공장 생산 통제 등)의 경우 어떤 방법이든 참조 방법과 적절한 작업 관계를 갖추었다면 사용할 수 있습니다. 비고 1: 고급 실험 방법의 예는 참고 문헌에서 찾을 수 있습니다. 이 문서는 사이즈 분획 4/63mm 내에 있는 입자로 구성된 거친 암석 집합물에 적용됩니다. 가벼운 암석 집합물에는 적용되지 않습니다. 비고 2: 4mm부터 20mm까지의 거친 암석 집합물에 대해 제철 면적의 비율은 유동 계수와 연결되어 있으며, 따라서 EN 933-6에 명시된 시험 방법과 함께 사용할 수 있습니다. 7.1항은 하나의 크기 분획으로 이루어진 시험 샘플에 대한 절차를 규정하고, 7.2항은 두 개 이상의 크기 분획으로 이루어진 시험 샘플에 대한 절차를 규정합니다. 알찬 부록 A에서는 약 100개의 입자를 포함하는 다양한 크기 분획의 예상 질량에 대한 지침이 제공됩니다. 시험 절차의 응용 예 및 시험 데이터 시트에 대한 예시를 설명하는 부록 B 및 C도 제공됩니다.
The article discusses EN 933-5:2022, a standard that specifies the method for determining the percentage of crushed particles in coarse and all-in natural aggregates. This method is used for type testing and dispute resolution. Other methods can be used for different purposes as long as they are compatible with the reference method. The standard applies to coarse aggregates within the size range of 4/63 mm and does not cover lightweight aggregates. The article also provides details on test procedures for different size fractions and includes informative annexes with guidance and examples of applying the test procedure.
