Tests for geometrical properties of aggregates - Part 8: Assessment of fines - Sand equivalent test

This European Standard describes the reference method used for type testing and in case of dispute for the determination of the sand equivalent value of 0/2 mm fraction (for 0/4 mm, see Annex A) in fine aggregates or all-in aggregates. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established.

Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 8: Beurteilung von Feinanteilen - Sandäquivalent-Verfahren

Diese Europäische Norm beschreibt das Referenzverfahren, das für die Erstprüfung und im Streitfall für die Bestimmung des Sandäquivalent-Werts für die Kornklasse 0/2 mm (für 0/4 mm, siehe Anhang A) in feinen Gesteinskörnungen angewendet wird. Für andere Zwecke, speziell im Rahmen der werkseigenen Produk-tionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang mit dem Referenzverfahren nachgewiesen wurde.

Essais pour déterminer les caractéristiques géométriques des granulats - Partie 8 : Evaluation des fines - Equivalent de sable

La présente norme européenne décrit la méthode de référence utilisée pour les essais de type
initiaux ainsi qu’en cas de litige dans le but de déterminer l’équivalent de sable de la fraction 0/2 mm
(pour 0/4 mm, voir l’Annexe A) des sables et des graves. A d’autres fins, en particulier pour la
maîtrise de la production des granulats, d’autres méthodes peuvent être utilisées à condition qu’il
existe une relation entre ces dernières et la méthode de référence.

Preskusi geometričnih lastnosti agregatov - 8. del: Ugotavljanje finih delcev - Ekvivalent peska

Ta evropski standard opisuje referenčno metodo, ki se uporablja za tipsko preskušanje in v primeru spora za ugotavljanje vrednosti ekvivalenta peska deleža 0/2 mm (za 0/4 mm glejte Dodatek A) v finih agregatih ali nesepariranih agregatih. Za druge namene, zlasti za kontrolo proizvodnje v obratu, se lahko uporabijo druge metode, če obstaja primerna delovna povezava z referenčno metodo.

The other parts of EN 933, Tests for geometrical properties of aggregates, will be:

 Part 1: Determination of particle size distribution — Sieving method;

 Part 2: Determination of particle size distribution — Test sieves, nominal size of apertures;

 Part 3: Determination of particle shape — Flakiness index;
 Part 4: Determination of particle shape — Shape index;

 Part 5: Determination of percentage of crushed and broken surfaces in coarse aggregate

particles;

 Part 6: Assessment of surface characteristics — Flow coefficient of aggregates;

3.6
test specimen

sample used in a single determination when a test method requires more than one determination of a

property
4 Principle

A 0/2 mm test specimen of aggregate with a maximum fines content of 10 % (either natural or

obtained after grading curve adjustment) and a small quantity of washing and flocculating solution are

poured into a graduated cylinder and are agitated to loosen the clay coatings from the coarser

particles in the test portion. The aggregate is then ‘irrigated’ using additional washing and flocculating

solution forcing the fine particles into suspension. After a fixed time, the sand equivalent value

(SE(10)) is calculated as the height of sediment expressed as a percentage of the total height of

sediment and suspension in the cylinder.
5 Reagents
5.1 Concentrated solution, made up of:

a) crystalline calcium chloride, CaCl .6H O or anhydrous calcium chloride, CaCl ;

2 2 2
b) glycerine, 99 % glycerol, laboratory reagent quality;
c) formaldehyde solution, 40 % by volume, laboratory reagent quality;
d) distilled or demineralised water.

Dissolve (219 ± 2) g of crystalline calcium chloride in (350 ± 50) ml of distilled or demineralised water,

cool to room temperature and if necessary filter through a medium or coarse grade filter paper. Add

(480 ± 5) g of glycerine and (12,5 ± 0,5) g of formaldehyde solution and dilute to 1 l of solution with

distilled or demineralised water and mix thoroughly.

NOTE 1 219 g CaCl .6H 0 6H O is equivalent to 111 g anhydrous calcium chloride CaCl .

NOTE 2 It is recommended that the concentrated solution is stored protected from light in glass or plastics

flasks containing (125 ± 1) ml.

NOTE 3 Sodium hypochlorite (bleach) with 2,6 % active chloride can be used instead of formaldehyde. In

case of dispute, use formaldehyde.

5.2 Washing and flocculating solution, prepared by diluting (125 ± 1) ml concentrated

solution (5.1) to (5,00 ± 0,01) l using distilled or demineralised water.

NOTE In preparing the washing solution, the concentrated solution should first be vigorously shaken and

subsequently its container should be rinsed several times u
