37、ulic and/or pozzolanic and/or sulphatic and/or carbonatic reaction, which usually has a workability to suit compaction by rolling and which is generally used in bases, sub-bases and capping layers 3.2 compressive strength stress at failure of a specimen when tested in uniaxial unconfined compression
38、 3.3 slenderness ratio ratio of the length to the diameter of a cylindrical specimen 4 Principle A specimen is subjected to a compressive force until failure. The maximum load sustained by the specimen is recorded and the compressive strength is calculated. Licensed Copy: sheffieldun sheffieldun, na

NOTE 1Test specimens of hydraulically bound mixtures
40、 can be either cylindrical or cubical, with nominal dimensions as small as 50 mm (diameter) and as large as 300 mm (height), and with ultimate compressive strengths varying from 0,5 N/mm2 to normal concrete strengths. Machines complying with EN 12390-4 can be suitable for stronger specimens. The mac
41、hine shall have two steel loading platens with faces having a Rockwell hardness of at least 55 HRC for a depth of approximately 5 mm. The loading platens shall be at least as large as, and preferably larger than, the faces of the specimen to which the load is applied. The surface flatness of the pla
42、tens and the surfaces by which they are supported shall be 0,03 mm or better. NOTE 2Auxiliary platens having a minimum thickness of 25 mm and fulfilling the same requirements as the original platens can be used. The upper platen shall have a spherical seating of dimension such that the deformation o
43、f the platen under normal loading does not exceed the tolerance of flatness. The combination of the upper platen and spherical seating shall be designed to permit easy alignment of the platen to the specimen but to become immobile as the force on the specimen increases. The seating shall have its ce
44、ntre at the surface of the platen, or at a point whose distance from the platens is less than 1 mm. The diameter of the seating shall not exceed 150 mm. Provision shall be made for positive location of specimens at the centre of the lower platens; visual alignment shall not be used. 6 Test specimen
45、Manufacture of the test specimen The manufacture of the specimen shall be in accordance with prEN 13286-50, prEN 13286-51, prEN 13286-52 or prEN 13286-53. The type of compaction and curing of the specimen shall be stated in the test report. 7 Test procedure 7.1 Dimensions The dimensions of the speci
46、men shall be measured with an accuracy of 0,5 %. 7.2 Mass The specimen shall be weighed to an accuracy of 0,25 % and compared to the mass at the time of manufacture. The change in mass shall be recorded. NOTEIf the change in mass is greater than 2 %, the resulting compressive strength can be reviewe
47、d since it could be unrepresentative of the tested mixture. 7.3 Adjustment of the test specimen The top and bottom faces of the test specimen shall have an out-of-parallelism tolerance not exceeding 2 mm in 100 mm. Specimens failing this requirement shall either be discarded or rectified by grinding
48、 or capping in accordance with annex A of EN 12390-3:2001.

49、e wiped from the surface of the specimen before placing in the test machine. All testing machine bearing surfaces shall be wiped clean and any loose grit or extraneous material removed from the surfaces of the specimen that will be in contact with the platens or auxiliary platens if used. No packing shall be used between the specimen and the platens or auxiliary platens. Cube specimens shall be compressed perpendicularly to or in the direction of casting and the direc
