SS- Provläsningsexemplar / Preview 1 Scope This European Standard describes a simple method for the examination of coarse recycled aggregates for the purpose of identifying and estimating the 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 been 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 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 932-1, Tests for general properties of aggregates Part 1 Methods for sampling 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 EN 933-2, Tests for geometrical properties of aggregates Part 2: Determination of particle 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 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 i /D i fraction of an aggregate passing the larger (D i ) of two sieves and retained on the smaller (d 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 predetermined 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. 4
SS- 3.4 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 test 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 stated, 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 scale, of suitable capacity and readable to 0,1g. 5.5 Trays 5.6 Brushes 5.7 Sieving machine, optional. 5.8 Watertight tank, of suitable capacity. 5.9 Stirrer 5.10 Dry soft absorbent rag 5.11 Graduated measuring cylinder, of suitable capacity, graduated to 1 or 5 cm 3 (depending on the required precision for volume measurement). 5.12 Plunger, for the graduated cylinder. 5
SS- Provläsningsexemplar / Preview 6 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 sample at (40 ± 5) C to constant mass. Weigh and record the dry mass of the sample as M 0. 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 with 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 M 63, and then discard them. Weigh and record the mass of particles passing the 4 mm sieve as M 4, and then discard them. Record the mass of the obtained test portion as M 1. Table 1 Guidance on mass of test portion Upper Aggregate size D Test portion mass (minimum) mm Kg 63 50 32 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 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 V FL in cm 3. 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. 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 belonging 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 M X. 6

To facilitate the sorting, the number of these particles can be further reduced to at least 1000 particles according to EN 932-2. 7
