EN 196-1:2016 (E) DIN EN 196-1:2016-11 5 1 Scope This part of EN 196 describes the method for the determination of the compressive and, optionally, the flexural strength of cement mortar. The method applies to common cements and to other cements and mater
27、ials, the standards for which call up this method. It may not apply to other cement types that have, for example, a very short initial setting time. The method is used for assessing whether the compressive strength of cement is in conformity with its specification and for validation testing of a CEN
28、 Standard sand, EN 196-1, or alternative compaction equipment. This part of EN 196 describes the reference equipment and procedure and allows alternative compaction equipment and procedures to be used provided that they have been validated in accordance with the appropriate provisions in this docume
29、nt. In the event of a dispute, only the reference equipment and procedure are used. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For un
30、dated references, the latest edition of the referenced document (including any amendments) applies.

34、l, strength of prismatic test specimens 40 mm 40 mm 160 mm in size. These specimens are cast from a batch of plastic mortar containing one part by mass of cement, three parts by mass of CEN Standard sand and one half part of water (water/cement ratio 0,50). CEN Standard sands from various sources an
35、d countries may be used provided that they have been shown to give cement strength results which do not differ significantly from those obtained using the CEN Reference sand (see Clause 11). EN 196-1:2016 (E) DIN EN 196-1:2016-11 6 In the reference procedure the mortar is prepared by mechanical mixi
36、ng and is compacted in a mould using a jolting apparatus. Alternative compaction equipment and procedures may be used provided that they have been shown to give cement strength results which do not differ significantly from those obtained using the reference jolting apparatus and procedure (see Clau
37、se 11 and Annex A). The specimens are stored in the mould in a moist atmosphere for 24 h and, after demoulding, specimens are stored under water until strength testing. At the required age, the specimens are taken from their wet storage, broken in flexure, determining the flexural strength where req
38、uired, or broken using other suitable means which do not subject the prism halves to harmful stresses, and each half tested for strength in compression. 4 Laboratory and equipment 4.1 Laboratory The laboratory where preparation of specimens takes place shall be maintained at a temperature of (20 2)
39、C and a relative humidity of not less than 50 %. The moist air room or the large cabinet for storage of the specimens in the mould shall be maintained at a temperature of (20,0 1,0) C and a relative humidity of not less than 90 %. The storage containers for curing the specimens in water, and the gra
40、tes with which they are fitted, shall be of material which does not react with cement. The temperature of the water shall be maintained at (20,0 1,0) C. The temperature and relative humidity of the air in the laboratory and the temperature of the water in the storage containers shall be recorded at
41、least once a day during working hours. The temperature and relative humidity of the moist air room or cabinet shall be recorded at least every 4 h. Cement, CEN Standard sand (see 5.1.3), water and apparatus used to make and test specimens shall be at a temperature of (20 2) C. Where temperature rang
42、es are given, the target temperature at which the controls are set shall be the middle value of the range. 4.2 General requirements for the equipment The tolerances shown in Figures 1 to 5 are important for correct operation of the equipment in the testing procedure. When regular control measurement
43、s show that the tolerances are not met, the equipment shall be rejected, adjusted or repaired. Records of control measurements shall be kept. Acceptance measurements on new equipment shall cover mass, volume, and dimensions to the extent that these are indicated in this document paying particular at
44、tention to those critical dimensions for which tolerances are specified. In those cases where the material of the equipment can influence the results, the material is specified and shall be used. The approximate dimensions shown in the figures are provided as guidance to equipment manufacturers or o
45、perators. Dimensions, which include tolerances, are obligatory. EN 196-1:2016 (E) DIN EN 196-1:2016-11 7 4.3 Test sieves Wire cloth test sieves conforming to ISO 3310-1 shall be of the sizes from ISO 565 given in Table 1 (series R 20). Table 1 Aperture of test sieves Square mesh size (mm) 2,00 1,60
46、1,00 0,50 0,16 0,08 4.4 Mixer The mixer shall consist essentially of: a) a stainless steel bowl with a capacity of about 5 l of the typical shape and size shown in Figure 1, provided with means by which it can be fixed securely to the mixer frame during mixing and by which the height of the bowl in
47、relation to the blade and, to some extent, the gap between blade and bowl can be finely adjusted and fixed; b) a stainless steel blade of the typical shape, size and tolerances shown in Figure 1, revolving about its own axis as it is driven in a planetary movement around the axis of the bowl at cont
48、rolled speeds by an electric motor. The two directions of rotation shall be opposite and the ratio between the two speeds shall not be a whole number. Blades and bowls shall form sets which shall always be used together. The gap of (3 1) mm refers to the situation when the blade in the empty bowl sh
49、own in Figure 1 is brought as close as possible to the wall. This gap shall be checked regularly applying minimal pressure to the blade and assuring that there is no perceptible clearance between the joint of the blade and the axis of the motor. NOTE 1 Simple tolerance gauges (feeler gauges) are useful where direct measurement is difficult. NOTE 2 The dimensions marked as approximate on Figure 1 are for the guidance of manufactu
