3、3 EN 933-11:2009 (E) 3 Foreword This document (EN 933-11:2009) 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 endorsem
4、ent, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. 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 identify
5、ing any or all such patent rights. This European Standard is one of a series of standards for tests for geometrical properties of aggregates. Test methods for other properties of aggregates are covered by parts of the following European Standards: EN 932 Tests for general properties of aggregates EN
6、 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 are: Part 1: Determination
7、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 a
8、nd broken surfaces in coarse aggregate particles Part 6: Assessment of surface characteristics - Flow coefficient of aggregates Part 7: Determination of shell content - Percentage of shells in coarse aggregates Part 8: Assessment of fines - Sand equivalent test Part 9: Assessment of fines - Methylen
9、e blue 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, Denmar
10、k, 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. EN 933-11:2009 (E) 4 1 Scope This European Standard describes a
11、 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 co
12、ntrol, 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,
13、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 refe
14、renced 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
15、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 design
16、ation 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 di/Di fraction of an
17、aggregate passing the larger (Di) of two sieves and retained on the smaller (di) 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 i
18、n 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. EN 933-11:2009 (E) 5 3.4 floating particles particles that float in water 3.5 test portion sample us
19、ed 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 proport
20、ion 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, th
21、ermostatically 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 measur
