DIN EN 933-11:2011-05 EN 933-11:2009 (E) 31 Scope This European Standard describes a simple method for the examination of coarse recycled aggregates for the purpose of identifying and estimating the

23、relative proportions of constituent materials. This reference test method should be used for type testing and in case of dispute. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has be

24、en established. NOTE 1 This method is not appropriate for lightweight aggregates covered by EN 13055 series. NOTE 2 If dangerous substances are found in while carrying out this method, they should be dealt with in accordance with regulations in the place of use. 2 Normative references The following

27、e size distribution Test sieves, nominal size of apertures 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 t

28、he 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 di/Difraction of an aggregate passing the larger (Di) of two sieves and retained on the smaller (di) 3.3 constant mass successive weighi

29、ngs 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 speci

30、fic types and sizes of sample dependent upon the drying capacity of the oven used. DIN EN 933-11:2011-05 EN 933-11:2009 (E) 43.4 floating particles particles that float in water 3.5 test portion sample used as a whole in a single test 4 Principle The test consists of hand sorting particles from a te

31、st portion of coarse recycled aggregate into a list of constituents. The proportion of each constituent in the test portion is then determined and expressed as a percentage by mass, except for the proportion of floating particles which is expressed as a volume by mass. 5 Apparatus Unless otherwise s

32、tated, all apparatus shall conform to the general requirements of EN 932-5. 5.1 Test sieves, 63 mm and 4 mm conforming to EN 933-2. 5.2 Tightly fitting pan and lid, for the sieves. 5.3 Ventilated oven, thermostatically controlled to maintain a temperature of (40 5) C or (110 5) C. 5.4 Balance or sca

34、for volume measurement). 5.12 Plunger, for the graduated cylinder. DIN EN 933-11:2011-05 EN 933-11:2009 (E) 56 Preparation of test portion The sample shall be taken in accordance with EN 932-1 and reduced in accordance with EN 932-2 to produce a test portion of minimum mass given in Table 1. Dry the

35、 sample at (40 5) C to constant mass. Weigh and record the dry mass of the sample as M0. NOTE In the absence of temperature sensitive constituents such as bituminous mixtures, the sample may be dried at (110 5) C. Record the drying temperature as T. Sieve the sample on the test sieves, agitating wit

36、h sufficient vigour to ensure complete separation of particles greater than 4 mm. Weigh and record the mass of particles retained on the 63 mm sieve as M63, and then discard them. Weigh and record the mass of particles passing the 4 mm sieve as M4, and then discard them. Record the mass of the obtai

37、ned test portion as M1. Table 1 Guidance on mass of test portion Upper Aggregate size D Test portion mass (minimum) mm Kg63 5032 and below 20 Note Higher test portion masses may be necessary to ensure sufficient precision in the determination of low proportions of restricted constituents, (see Annex

38、 A). 7 Procedure Separate and retain clay and soil from the test portion and put it in a tray. Immerse the rest of the test portion into the filled watertight tank and stir in order to wash the particles and release the floating ones. Collect these floating particles and determine their volume VFLin

39、 cm3. For this purpose, gently surface dry them using the dry absorbent rag, then introduce them into the graduated cylinder filled with a known volume of water, sufficient to allow their total immersion. Use the plunger to achieve total immersion of the floating particles alone (see Figure 1), viz.

40、 do not immerse the plunger itself or entrap air, and use the cylinder gradation to assess the resulting volume increase. Collect the non-floating particles and dry them apart at same temperature as before to constant mass. Spread these particles on a flat surface and separate by hand those belongin

41、g to constituent X as defined in Table 2. Put them in the tray together with the soil and the clay. Weigh and record the combined mass of particles as MX.

To facilitate the sorting, the number

44、of these particles can be further reduced to at least 1000 particles according to EN 932-2. DIN EN 933-11:2011-05 EN 933-11:2009 (E) 7Table 3 gives guidance on the minimum mass required for this purpose.

The actual mass depends upon the particle size distribution and particle density of the aggregate. Experience will allow test laboratories to estimate the mass required for materials that

46、are tested routinely. Weigh and record the mass of the non-floating particles that remain to be sorted as M3. Separate them further into the constituents described in Table 2. Weigh and record the masses of each constituent as MRc, MRu, MRb, MRa, and MRg. Figure 2 summarizes the various steps of the
