28、ing cylindrical specimens of hydraulically bound mixtures to a predetermined density and moisture content by axial compression. This document applies to mixtures, or that part of a mixture, containing aggregate up to a maximum size of 22,4 mm, and for mixtures that have sufficient fines or cohesion

29、to allow extrusion without damage immediately after compaction. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 13286-53:2004 (E) 6 5 Principle Cylindrical test specimens of the mixture are made by axial compression. After demoulding, the specimens are

34、 stored at a specified temperature and for a specified period of time minimizing loss of moisture until required for testing. NOTE The method described usually produces specimens with a density gradient such that the density in the central part of the specimen is less than that at the ends. 6 Dimens

35、ions of the specimens Specimens shall conform to the dimensions given in Table 1. Table 1 Specimen dimensions Column 1 2 3 Line d mm h mm Maximum size of particle permitted in the specimen mm 1 50 50 or 100 11,2 2 100 100 or 200 22,4 7 Apparatus 7.1 Moulds, with dimensions conforming to the followin

36、g (see Figure 1), according to the size of specimen selected from Table 1: a) internal diameter (d 0,1) mm; b) minimum height for cylinder with a slenderness ratio of 2 1,7 h; c) minimum height for cylinder with a slenderness ratio of 1 2,4 h; d) minimum wall thickness 10 mm. Each mould shall have f

37、langed pistons (plugs) for each end of the mould with dimensions as follows: e) external diameter (d 0,5 mm) 0,1 mm; f) minimum height 0,7 d. The length of the plugs and the moulds shall be such that the free space in the middle part of the mould is (h 0,2) mm when the flanges of the 2 plugs are in

38、contact with the barrel of the mould. 7.2 Displacing half-collars conforming to Figure 2, three pairs of which are used between the flanges of the plugs and the barrel of the cylinder during the filling and compaction procedure in order to minimize density gradients within the specimen. The displace

39、ment depth of the collars shall conform to Table 2. EN 13286-53:2004 (E) 7 Table 2 Displacement depth of the collars Pair number E 1 h/4 2 h/6 3 h/10 7.3 Compaction press or compression testing machine, capable of exerting sufficient force in a controlled manner without vibration to achieve compacti

40、on of the specimen. 7.4 11,2 mm and 22,4 mm test sieves, conforming to EN 933-2. 8 Procedure 8.1 Sieve the mixture on the 11,2 mm sieve for 50 mm diameter specimens and on the 22,4 mm sieve for 100 mm diameter specimens and use only the fraction passing the appropriate sieve for the manufacture of t

41、he specimens. 8.2 Calculate the mass of the mixture required for moulding using the following formula: () 100 100 000 1 d w V m + = where m is the mass of the mixture to be introduced in the mould, in grams (g); V volume of the specimen, in cubic millimetres (mm 3 ); dis the dry density of the speci

42、men, in megagrams per cubic metre (Mg/m 3 ); w is the water content of the dry mass of the mixture, in percent (%). 8.3 Introduce pair number 1 of the displacing collars between the flange of the bottom plug and the barrel of the mould. 8.4 Place the total quantity of mixture into the mould. During

43、filling, tamp the material gently and uniformly. 8.5 Insert the upper plug into the mould. Replace pair number 1 of the displacing collars with pair number 2. 8.6 Place the mould between the platens of the press or compression machine. Apply pressure smoothly so the upper plug can be fully inserted

44、at the slowest and most constant speed possible. 8.7 When the flange of the upper plug is in contact with the barrel of the mould, release the pressure and replace pair number 2 of the displacing collars with pair number 3. 8.8 Recommence the compaction so that full penetration of the bottom plug ta

45、kes at least 10 s. 8.9 Remove pair 3 of the displacing collars. The pressure shall be maintained for at least 10 s after the flanges are in full contact with the mould barrel. EN 13286-53:2004 (E) 8 8.10 If the maximum pressure exceeds 3 MPa, the required density or water content of the mixture shal

46、l be modified and the process repeated. NOTE It is also practice to employ apparatus that uses just one pair of displacing collars. Provided the penetration of the 2 plugs is similar during compaction, the above procedure can be modified accordingly. 8.11 Immediately on completion of compaction, car

47、efully remove the plugs and using a plunger, smoothly extrude the specimen from the mould. The speed of this operation shall not exceed 2 mm/s. 8.12 Determine immediately the mass of the specimen to the nearest 5 g and then store as in Clause 9. 9 Storage Specimens shall be stored vertically, preven

48、ting loss of moisture, at a temperature within 2 C of the specified temperature, for the time specified in the relevant mixture document. 10 Test report The test report shall include the following information: a) reference to this document; b) type of mixture; c) origin of the mixture; d) preparation of the mixture where applicable; e) percentage by mass of mixture retained on the 11,2 mm or 22,4 mm sieve if any; f) mass, water content and dry density of the specime
