32、nd definitions For the purposes of this document, the terms and definitions given in EN 13286-4:2003 and the following apply. 3.1 vibrating hammer compaction to refusal method of manufacture of a laboratory test specimen by compacting in layers an undefined quantity of mixture into a mould of known

33、volume using a vibrating hammer and tamper until no further compaction is possible (refusal) 4 Principle Cylindrical or cubical specimens of the mixture are made by vibrating hammer compaction to refusal. After compaction, the specimens are stored at a specified temperature and for a specified perio

34、d of time minimizing loss of moisture until required for testing. 5 Dimensions of the specimens Specimens shall conform to the dimensions given in Table 1. EN 13286-51:2004 (E) 6 Table 1 Nominal specimen dimensions for cubes and cylinders Column 1 2 3 Specimen diameter or cube dimension, d Specimen

35、height, h Maximum size of particle permitted in the specimen Line mm mm mm 1 100 100 22,4 2 150 150 31,5 6 Apparatus 6.1 Cylindrical specimens 6.1.1 Moulds, whose dimensions conform to the specimen requirements in Table 1. The moulds shall be strong enough to prevent distortion during compaction and

36、 shall be capable of being held rigidly in place with their base-plates during compaction. NOTE Either metal, split or plastic moulds can be employed. Plastic moulds have been found to be particularly convenient for slow setting mixtures since the specimen can be left in the mould until the time of

37、test. Reusable or disposable plastic moulds are also suitable for mixtures that need to be contained during storage that would otherwise disintegrate on extrusion from the mould immediately after compaction. Plastic moulds are also more suitable for mixtures that are corrosive to metal. 6.1.2 Vibrat

38、ing hammer, electric or pneumatic, conforming to EN 13286-4. 6.1.3 Steel circular tampers, with nominal diameters of 0,6 d and 0,95 d. 6.2 Cubical specimens 6.2.1 Moulds, whose dimensions conform to the specimen requirements in Table 1 and which conform to EN 12390-1. 6.2.2 Vibrating hammer, electri

39、c or pneumatic, conforming to EN 13286-4. 6.2.3 Steel square tampers, with nominal dimensions 0,6 d and 0,95 d. 6.3 Sieves 22,4 mm and 31,5 mm test sieves conforming to EN 933-2. 6.4 Straight edge Steel straight edge with length equal to or greater than twice the maximum internal mould diameter or w

40、idth as applicable. 7 Procedure 7.1 Sieve the mixture on the 22,4 mm sieve for 100 mm specimens or on the 31,5 mm sieve for 150 mm specimens and use only the fraction passing the appropriate sieve for the manufacture of the specimens. EN 13286-51:2004 (E) 7 7.2 In the case of specimens that will not

41、 be extruded from the mould immediately after compaction, determine the mass of the mould to the nearest 5 g. 7.3 Using the tamper with dimension 0,6 d fitted to the vibrating hammer, compact the mixture into the mould in approximately 50 mm layers until it is deemed that no further compaction is po

42、ssible (1 min per layer is usually sufficient). Before the next layer is added, scarify the previously compacted layer. 7.4 On completion of compaction of the final layer, strike off excess mixture with a straight edge and fill any depressions with fine mixture from the sample using a combination of

43、 the vibrating hammer fitted with the tamper of dimension 0,95 d and trowel. NOTE In order to produce a specimen with sound parallel top and bottom faces, it may be necessary to cap the specimen. It may be convenient to carry this out at this stage. 7.5 For cylindrical specimens, proceed as follows

44、or as in 7.6. Carefully extract or extrude the specimen from the mould. With extrusion, the speed of this operation shall not exceed 2 mm/s. Determine immediately the mass of the specimen to the nearest 5 g and then store as in Clause 8. 7.6 For cylindrical specimens that are to be kept in their mou

45、lds during storage, determine immediately the mass of the specimen and mould to the nearest 5 g and by difference, the mass of the specimen. Then store as in Clause 8. 7.7 For cubical specimens, determine immediately the mass of the specimen and mould to the nearest 5 g and by difference, the mass o

46、f the specimen. Cover the specimen to prevent moisture loss and maintain at a temperature within 5 C of the specified temperature until demoulding takes place. Then store as in Clause 8. 7.8 Using the nominal dimensions of the mould and the mass of the specimen, determine the wet density of the spec

47、imen. 8 Storage Specimens shall be stored vertically, preventing loss of moisture, at a temperature within 2 C of the specified temperature, for the time specified in the relevant mixture document. In the case of specimens stored in their moulds, carefully extrude the specimen just prior to testing.

48、 The speed of this operation shall not exceed 2 mm/s. 9 Test report The test report shall include the following information: a) reference to this document; b) type of mixture; c) origin of the mixture; EN 13286-51:2004 (E) 8 d) any preparation of the mixture where applicable; e) percentage by mass o

49、f mixture retained on the sieve if any; f) mass and nominal wet density of the specimen immediately after compaction; g) storage conditions of the specimen; h) any deviations from this document as well as any incidents that could have an effect on the result. blankBS EN 13286-51:2004 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing Bri
