La présente Norme européenne décrit une méthode simple d’examen des gravillons recyclés afin d’identifier
et d’estimer les proportions relatives des différents constituants. Il convient d’utiliser cette méthode d’essai de
référence pour tous les essais de type, de même qu’en cas de litige. Á d’autres fins, en particulier pour le
contrôle de la production en usine, d’autres méthodes peuvent être utilisées à condition qu’il existe une
relation entre ces dernières et la méthode de référence.

Overview

EN 933-11:2009 - Tests for geometrical properties of aggregates, Part 11 - provides a reference classification test for the constituents of coarse recycled aggregate. Published by CEN, this standard describes a simple, reproducible method for identifying and estimating the relative proportions of constituents in coarse recycled aggregates (e.g., concrete, masonry, unbound rock, bituminous material, glass, and miscellaneous items). It is intended as a reference method for type testing and dispute resolution; alternative methods may be used for factory production control if an appropriate working relationship with this reference method is established.

Key topics and technical requirements

• Scope and limits: Applies to coarse recycled aggregates (4 mm – 63 mm fractions). Not appropriate for lightweight aggregates covered by EN 13055.
• Sample preparation: Sampling and reduction in accordance with EN 932-1 and EN 932-2. Test portion masses are specified (e.g., minimum 50 kg for D = 63 mm; 20 kg for D ≤ 32 mm).
• Sieving: Use 63 mm and 4 mm sieves (EN 933-2) to isolate the 4/D fraction to be examined.
• Drying: Dry to constant mass at (40 ± 5) °C (or 110 ± 5 °C where appropriate) and record drying temperature.
• Constituent sorting: Hand-sort non-floating particles into defined classes (Rc concrete/mortar, Ru unbound aggregate, Rb clay masonry, Ra bituminous, Rg glass, X other/cohesive). Clay/soil are separated and recorded.
• Floating particles: Floating constituents are collected by immersion and their volume V determined using a graduated cylinder and plunger; results expressed as volume per unit mass (cm3/kg). Formulae for calculating proportions are provided (e.g., FL (cm3/kg) = 1000 × V / M1).
• Reporting and rounding: Constituent proportions are reported by mass (%) except floating particles. Percentages rounded to one decimal (except ≥10 % - no decimal). Test report must reference EN 933-11 and include sample and lab identification, drying temperature, date, and constituent proportions.
• Annex A: Procedure for improved precision when floating particles are present in very low proportions (large test portions and water-content correction).

Applications and users

• Quality control and type testing of recycled coarse aggregates for concrete and construction products
• Independent testing laboratories and national testing authorities for dispute resolution
• Aggregate producers, concrete manufacturers, precast plants and specifiers establishing compliance and material composition
• Product certification bodies and environmental/recycling managers monitoring recycled aggregate quality

Related standards

• EN 933 series (other parts cover particle size, shape indices, fines, etc.)
• EN 932 series (sampling and sample reduction)
• EN 933-2 (test sieves) and EN 932-5 (equipment and calibration)
• Note: EN 13055 for lightweight aggregates (method not applicable)

3 Terms and Definitions
For the purpose of this standard, the following terms and definitions apply:
3.1
aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D
NOTE This designation accepts the presence of some particles which will be retained on the upper sieve
(oversize) and some which will pass the lower sieve (undersize).
3.2
particle size fraction d /D
i i
fraction of an aggregate passing the larger (D ) of two sieves and retained on the smaller (d)
i i
3.3
constant mass
successive weighings after drying at least 1 h apart not differing by more than 0,1 %
NOTE 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 capacit
