27、DIN EN 933-1:2012-03 EN 933-1:2012 (E) 4 1 Scope This European Standard describes the reference washing and dry sieving method used for type testing and in case of dispute, for determination of the particle size distribution of aggregates. For other purposes, in particular factory production control

28、, other methods may be used, provided that an appropriate working relationship with the reference method has been established. It applies to all aggregates, including lightweight aggregates, up to 90 mm nominal size, but excluding filler. NOTE 1 The determination of the grading of fillers is specifi

NOTE 2 Dry sieving without washing may be used for aggregates free from particles which cause agglomeration. 2 Normative references The following referenced documents are indispensable for the application of this doc

33、red or recycled 3.2 test portion sample used as a whole in a single test 3.3 constant mass mass determined by successive weighings performed at least 1 h apart and 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-determin

34、ed period in a specified oven (see 5.3) at (110 5) C. Test laboratories may determine the time required to achieve constant mass for specific types and sizes of sample dependent upon the drying capacity of the oven used. DIN EN 933-1:2012-03 EN 933-1:2012 (E) 5 4 Principle The test consists of divid

35、ing and separating a material into several particle size classifications of decreasing sizes by means of a series of sieves,. The aperture sizes and the number of sieves are selected in accordance with the nature of the sample and the accuracy required. The method adopted is washing and dry sieving.

36、 When washing can alter the physical properties of a lightweight aggregate, dry sieving shall be used and the procedure specified in 7.1 shall not be applied. The mass of the particles retained on the various sieves is related to the initial mass of the material. The cumulative percentages passing e

37、ach sieve are reported in numerical form and, when required, in graphical form (see Annex D). 5 Apparatus Unless otherwise stated, all apparatus shall conform to the general requirements of EN 932-5. 5.1 Test sieves, with apertures as specified in EN 933-2 and conforming to the requirements of ISO 3

38、310-1 and ISO 3310-2. 5.2 Tightly fitting pan and lid, for the sieves. 5.3 Ventilated oven, thermostatically controlled to maintain a temperature of (110 5) C, or other suitable equipment for drying the aggregates, if it does not cause any particle size breakdown. 5.4 Washing equipment. 5.5 Balances

39、 or scales, accurate to 0,1 % of test portion mass. 5.6 Trays, brushes. 5.7 Sieving machine, (optional). 6 Preparation of test portions Samples shall be reduced in accordance with EN 932-2 to produce the required number of test portions. NOTE It may be necessary to moisten samples containing substan

40、tial amounts of fines before reduction to minimise segregation and loss of dust. The size of each test portion shall be as specified in Table 1. DIN EN 933-1:2012-03 EN 933-1:2012 (E) 6 Table 1 Minimum size of test portions Aggregate size D mass of aggregates volume of lightweight aggregates (litres

41、) (maximum) mm kg 90 80 -32 10 2,116 2,6 1,7 8 0,6 0,8 4 0,2 0,3 NOTE 1 For aggregates of other sizes below 90 mm, the minimum test portion mass may be interpolated from the masses given in Table 1 using the following formulae: M = (D/10)2where M = minimum mass of test portion in kg D = aggregate si

42、ze in mm NOTE 2 The precision of the test method may be reduced if the test portion size is less than the value in Table 1. In such a case, the test portion size should be stated in the test report (9.2). NOTE 3 For aggregates of particle density higher than 3,00 Mg/m3(see EN 1097-6), an appropriate

43、 correction should be applied to the test portion masses given in Table 1 based on the density ratio, in order to produce a test portion of approximately the same volume as those for aggregates of normal density. NOTE 4 For lightweight aggregates complying with EN 13055, use the volume column to cho

44、ose the appropriate minimum size of test portions. The volumes for other aggregate sizes may be interpolated. Sample reduction shall yield a test portion of size larger than the minimum but not of an exact predetermined value. Dry the test portion by heating at a temperature of (110 5) C to constant

45、 mass. Allow to cool, weigh and record the mass as M1. For some types of aggregate, drying at 110 C binds particles together sufficiently strongly to prevent separation of single particles during subsequent washing and/or sieving procedures. For such aggregates the procedure given in Annex B shall b

46、e adopted. For all-in aggregates with D equal to 31,5 mm or larger, the procedure described in Annex A may be used. 7 Procedure 7.1 Washing Place the test portion in a container and add sufficient water to cover the test portion. NOTE 1 A storage period of 24 h under water is helpful in breaking dow

47、n lumps. A dispersion agent may be used. Agitate the sample with sufficient vigour to result in complete separation and suspension of the fines. Wet both sides of a 0,063 mm sieve reserved for use in this test only, and fit a guard sieve (e.g. 1 mm or 2 mm) on top. Mount the sieves in such a way tha

48、t the suspension passing the test sieve can be run to DIN EN 933-1:2012-03 EN 933-1:2012 (E) 7 waste or, when required, collected in a suitable vessel. Pour the contents of the container on to the top sieve. Continue washing until the water passing the 0,063 mm test sieve is clear. NOTE 2 Care should be taken to prevent overloading, overflowing or damagin
