Tests for geometrical properties of aggregates - Part 9: Assessment of fines - Methylene blue test
This standard describes the reference method used for type testing and in cases of dispute for the determination of the methylene blue value of the 0/2 mm fraction in fine aggregates or all-in aggregates (MB). It also describes the reference method for the determination of the methylene blue value of the 0/0,125 mm fraction (MBF) in Annex A. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the suitable reference method has been established.
Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 9: Beurteilung von Feinanteilen-Methylenblau-Verfahren
Diese Norm legt das für die Erstprüfung und in Streitfällen anzuwendende Referenzverfahren für die Bestimmung
des Methylenblau-Werts für die Kornklasse 0/2 mm in feinen Gesteinskörnungen oder Korngemischen
fest. Ferner wird in Anhang A ein Referenzverfahren für die Bestimmung des Methylenblau-Werts für die
Kornklasse 0/0,125 mm (MBF) festgelegt. Für andere Zwecke, speziell im Rahmen der werkseigenen
Produktionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender
Zusammenhang zum Referenzverfahren nachgewiesen wurde.
Essais pour déterminer les caractéristiques géométriques des granulats - Partie 9 : Qualification des fines - Essai au bleu de méthylène
La présente norme décrit la méthode de référence utilisée pour les essais de type initial et, en cas de litige,
pour déterminer la valeur de bleu de méthylène de la fraction 0/2 mm dans les sables ou les graves (MB). Elle
décrit aussi la méthode de référence permettant de déterminer la valeur de bleu de méthylène de la
fraction 0/0,125 mm (MBF) dans l'Annexe A. Dans les autres cas, en particulier pour la maîtrise de la
production en usine, d’autres méthodes peuvent être utilisées sous réserve d’être en corrélation avec la
méthode de référence.

EN 933-9:2009 (E) 3 Foreword This document (EN 933-9:2009) has been prepared by Technical Committee CEN/TC 154 “Aggregates”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at the latest by January 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 933-9:1998. This Standard forms part of a series of tests for geometrical properties of aggregates. Test methods for other properties of aggregates will be covered by parts of the following European Standards: EN 932, Tests for general properties of aggregates EN 1097, Tests for mechanical and physical properties of aggregates EN 1367, Tests for thermal and weathering properties of aggregates EN 1744, Tests for chemical properties of aggregates EN 13179, Tests for filler aggregate used in bituminous mixtures The other parts of EN 933 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 for coarse aggregates Part 7: Determination of shell content — Percentage of shells in coarse aggregates Part 8: Assessment of fines — Sand equivalent test Part 10: Assessment of fines — Grading of fillers (air jet sieving) According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the suitable reference method has been established. 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 932-2, Tests for general properties of aggregates — Part 2: Methods for reducing laboratory samples EN 932-5, Tests for general properties of aggregates — Part 5: Common equipment and calibration 3 Terms and definitions For the purposes of this document the following terms and definitions apply. 3.1 subsample sample obtained by means of a sample reduction procedure 3.2 test portion sample used as a whole in a single test 3.3 fines particle size fraction of an aggregate which passes the 0,063 mm sieve 3.4 particle size fraction fraction of an aggregate passing the larger of two sieves and retained on the smaller NOTE The lower limit can be zero. 3.5 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 specimen 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. SIST EN 933-9:2009
EN 933-9:2009 (E) 5 4 Principle Increments of a solution of methylene blue are added successively to a suspension of the test portion in water. The adsorption of dye solution by the test portion is checked after each addition of solution by carrying out a stain test on filter paper to detect the presence of free dye. When the presence of free dye is confirmed the methylene blue value (MB or MBF) is calculated and expressed as grams of dye adsorbed per kilogram of the size fraction tested. NOTE A conformity check, adding a single quantity of dye solution equivalent to a specified limiting value and which may be used as part of a production control process, is described in Annex B. 5 Reagents 5.1 Dye solution, solution of standard or technical quality methylene blue, (10,0 ± 0,1) g/l (see Annex C). The maximum period of use of the solution shall be 28 days. It shall be stored away from light. 5.2 Distilled or demineralised water. 5.3 Kaolinite, of known methylene blue value (MBK) (see Annex D). NOTE Kaolinite of MBK value between 1 g and 2 g per 100 g of kaolinite is preferable in order to avoid excessive use of dye. 6 Apparatus All apparatus shall conform to the general requirements of EN 932-5. 6.1 Burette, with capacity of either 100 ml or 50 ml and graduation of either 1/10 ml or 1/5 ml, or one 5 ml and one 2 ml micro-pipette. 6.2 Filter paper, quantitative and ash-free (< 0,010 %); 95 g/m2; thickness 0,20 mm; filtration speed 75 s; pore size 8 µm. 6.3 Glass rod, length 300 mm; diameter 8 mm. 6.4 Impeller agitator, capable of controlled variable rotation rates up to (600 ± 60) min-1 with three or four impeller blades of (75 ± 10) mm diameter. NOTE Alternative types of mixer can be used if it can be shown that results obtained agree with results produced using an impeller agitator as specified above. 6.5 Balance, readable to 0,1 % of the mass to be weighed. 6.6 Stopwatch or stopclock, readable to 1 s. 6.7 Test sieve, 2 mm aperture, with guard sieve (if necessary). 6.8 Beaker, glass or plastic, capacity about 1 l or about 2 l. 6.9 Flask, glass, capacity 1 l. 6.10 Ventilated oven, thermostatically controlled to maintain a temperature of (110 ± 5) °C. 6.11 Thermometer, readable to 1 °C.
