28、 25 % of the compressive strength of the repair product or system under test, measured in accordance with EN 12190 3.2 compressive stress the force per unit area of the original cross section of a test specimen under the application of a compressive load 3.3 compressive strain the deformation produc
29、ed by a compressive stress expressed as the change per unit of the original dimension of the test specimen 3.4 elastic compressive strain the compressive strain measured immediately following the application of a load up to the elastic limit (see Figure 1) 3.5 shrinkage strain the strain due to shri
30、nkage measured at the control specimen Page 4 EN 13584:2003 Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 05:44:45 GMT+00:00 2006, Uncontrolled Copy, (c) BSI :48531 NE3002 (E) 5 3.6 creep strain the time-dependent amount of compressive strain above the elastic compressive strain measured un
31、der the application of a constant load (see Figure 1) 3.7 creep coefficient the ratio of creep strain to elastic compressive strain 3.8 elastic recovery strain the amount of compressive strain lost by a test specimen measured immediately following unloading to zero stress (see Figure 1) 3.9 creep re
32、covery strain the time-dependent amount of compressive strain lost by a test specimen following unloading to zero stress after the elastic recovery (see Figure 1) 3.10 creep recovery coefficient the ratio of creep recovery strain to elastic recovery strain 4 Principle In the test for creep in compre
33、ssion, a prism of 4:1 aspect ratio is subjected to a constant compressive load and the change in compressive strain with time is measured during the creep phase. After unloading the change of strain with time is measured during the creep recovery phase. The effect of superimposed shrinkage is taken
34、into consideration in the calculation of creep strain, elastic compressive strain etc. 5 Apparatus 5.1Compressive creep rig: comprising a support frame and flat jack arrangement capable of maintaining the creep load (see 3.1) along the longitudinal axis of the compressive creep test specimens (see 5
35、.5) for at least 26 weeks and be capable of applying a load at a rate of between 200 N/s and 1 000 N/s. The vertical pillars connecting the platens of the rig (see 5.2) shall have a stiffness (axial load/axial deflection) of not less than 250 kN/mm. They incorporate a means of adjustment to provide
36、a parallelism tolerance between the upper and lower platen of 0,06 mm. NOTEA suitable hydraulic compressive creep rig capable of testing two test specimens simultaneously is illustrated in Figure 2. The incorporation of a gas/oil accumulator in the hydraulic system serves to extend the time between
37、occasions when it will be necessary to pump oil in order to maintain the constant values for the duration of the test. The compressive load and hence the compressive stress applied to the test specimens can then be monitored by a load cell conforming to ISO 376 inserted between the upper test specim
38、ens and the upper platen of the rig. 5.2Load platens in contact with the specimens (see 5.5) shall have a stiffness (axial load/central deflection) of not less than 2 500 kN/mm to avoid excessive deformation during loadings. The flatness tolerance for the area of the platen in contact with the load
39、cell shall conform to EN 12390-1. 5.3Spacing blocks used between the test specimen and the flat jack (see 5.1) to reduce the test space and to compensate for any bow developed in the faces of the flat jack when under pressure. The spacing blocks are either circular or square in section, to enable th
40、e test specimens to be correctly centred and support them over the whole area of their ends. The property of the material, the surface flatness and the surface texture of the contact faces of all spacing blocks shall conform to EN 12390-1. 5.4Spherical seating is incorporated between the load cell (
41、see 5.1) and the top end piece of the compressive creep test specimen (see 5.5) to prevent eccentric loading. 5.5Moulds shall be of metal and suitable for the casting of the compressive creep test specimens in the form of prisms 40 mm x 40 mm x 160 mm within the tolerances for dimensions and shape o

The strain gauges shall be connected to equipment capa
43、ble of providing readings of the strain at any time. They shall be calibrated by a method traceable to a national or international standard of length measurement. The error shall not exceed 2 % of the actual strain. 5.7Standard laboratory climate, in accordance with annex A. 5.8Mixer of the standard
44、 type specified for producing cement mortars in EN 196-1 or forced action pan mixer for mixing the constituents of the repair mortar or concrete. 6 Preparation 6.1 General The following procedure shall be used to prepare a minimum of three specimens for the test, conforming to EN 12390-1. 6.2 Castin
45、g of test specimens The components of the product under test shall be maintained at the standard laboratory climate (see 5.7) for at least 24 hours before mixing. The repair product or system shall be mixed in accordance with the manufacturers recommendations and then compacted in the moulds to form
46、 the compressive creep test specimens. The specimens shall then be cured in accordance with annex A until ready for testing. NOTEFor preference, a suppliers complete pack of pre-weighted components should be used, but where this is not practicable the proportioning of the components should be strict
47、ly in accordance with the manufacturers recommended procedure. 6.3 Conditioning On completion of curing, the specimens shall be conditioned for at least 24 hours in the standard laboratory climate (see 5.7). For the total period of test, the test specimens and all parts of the test equipment in clos
48、e contact with them, if not the entire test equipment (see 5.1 to 5.4), shall be maintained under the standard laboratory conditions (see 5.7). 6.4 Measurement Measure the height, width and length of each specimen at the mid point of each side to an accuracy of 0,1 mm and calculate its cross-section
49、al area from the height and width 7 Procedure The following procedure shall be used for measuring the compressive creep of each specimen. 7.1 Preparation for testing Fit two strain gauges (see 5.6) to opposite cast sides of the test and control specimens, their gauge lengths being centrally located over the longitudinal axis of the specimens. Wipe clean the bearing surfaces of the load platens (see 5.2) and spacing blocks (see 5.3) of the creep rig, and the ends of the test specimens. Place
