DIN EN 196-3:2017-03 EN 196-3:2016 (E) 4 1 Scope This European Standard specifies the methods for determining standard consistence, setting times and soundness of cements. The method applies to common cements and to other ce

26、ments and materials, 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 setting time and soundness of a cement is in conformity with its specification. This part o

27、f EN 196 describes the reference methods and allows the use of alternative procedures and equipment, as indicated in notes, provided that they have been calibrated against the reference methods. In the event of a dispute, only the reference equipment and procedures are used. 2 Normative references T

28、he 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 undated references, the latest edition of the referenced document (including any amendments) applies. EN 196-1

29、, Methods of testing cement - Part 1: Determination of strength 3 Principles Cement paste of standard consistence has a specified resistance to penetration by a standard plunger. The water required for such a paste is determined by trial penetrations of pastes with different water contents. The sett

30、ing time is determined by observing the penetration of a needle into cement paste of standard consistence until it reaches a specified value. The soundness is determined by observing the volume expansion of cement paste of standard consistence as indicated by the relative movement of two needles. 4

31、Laboratory, equipment and materials 4.1 Laboratory The laboratory in which specimens are prepared and tested shall be maintained at a temperature of (20 2) C and a relative humidity of not less than 50 %. The temperature and relative humidity of the air in the laboratory and the temperature of the w

32、ater in the storage containers shall be recorded at least once per day during testing. Cement, water and apparatus used to make and test specimens shall be at a temperature of (20 2) C. NOTE See Annex A for storage conditions to be applied when testing setting times by alternative method. Where temp

33、erature ranges are given, the target temperature at which the controls are set shall be the middle value of the range. DIN EN 196-3:2017-03 EN 196-3:2016 (E) 5 4.2 Equipment and materials The tolerances shown in Figures 1 and 2 are important for correct operation of the equipment in the testing proc

34、edure. When regular control measurements 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 indicate

35、d in this document paying particular attention 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 g

36、uidance to equipment manufacturers or operators. Dimensions which include tolerances are obligatory. 4.2.1 Balance, capable of weighing to an accuracy of 1 g. 4.2.2 Graduated cylinder or burette, capable of dispensing to an accuracy of 1 ml. 4.2.3 Mixer, conforming to EN 196-1. NOTE A more homogeneo

37、us paste is produced at the lower limit of tolerance for the clearance between the blade and the bowl. 4.2.4 Water, distilled or deionized water shall be used for making the specimens. Drinking water may be used for storing and boiling specimens. 4.2.5 Timer, capable of measuring to an accuracy of 1

38、 s. 4.2.6 Measuring device, capable of measuring to an accuracy of 0,5 mm. 5 Standard consistence test 5.1 Apparatus Use the manual Vicat apparatus as shown in Figure 1a) and b) with the plunger shown in Figure 1c). The plunger shall be of non-corrodible metal in the form of a right cylinder of at l

39、east 45 mm effective length and of (10,00 0,05) mm diameter. The total mass of moving parts shall be (300 1) g. Their movement shall be truly vertical and without appreciable friction, and their axis shall coincide with that of the plunger. The Vicat mould (see Figure 1a) to contain the paste under

40、test shall be of hard rubber, plastics or brass. It shall be of cylindrical or preferably truncated conical form (40,0 0,2) mm deep and shall have an internal diameter of (75 10) mm. It shall be adequately rigid and shall be provided with a base-plate larger than the mould and at least 2,5 mm thick,

41、 constructed of impermeable material resistant to attack by cement paste, e.g. plane glass. Moulds of other metal may be used provided that they are of the specified depth and that their use has been calibrated against the specified mould. It is recommended that a laboratory uses base plates of equa

42、l thickness in order that the scale of the Vicat apparatus has only to be adjusted once for several determinations. DIN EN 196-3:2017-03 EN 196-3:2016 (E) 6 5.2 Procedure 5.2.1 Mixing the cement paste Weigh, to an accuracy of 1 g, by means of the balance (4.2.1), 500 g of cement and a quantity of wa

43、ter, e.g. 125 g. When water is measured by volume using the graduated cylinder or burette (4.2.2) it shall be dispensed to an accuracy of 1 ml. Mix each batch of paste mechanically using the mixer (4.2.3). The timing of the various mixing stages refers to the times at which mixer power is switched o

44、n/off and shall be maintained within 2 s. With the mixer in the operating condition: a) place the water and cement into the bowl taking care to avoid loss of water or cement; complete the addition within 10 s; b) immediately start the mixer at low speed while starting the timing of the mixing stages

45、. In addition, record the time to the nearest minute as zero time; NOTE Zero time is the point from which the initial (see 6.2) and final (see 6.3) setting times are calculated. c) stop the mixer after 90 s for 30 s during which remove by means of a suitable rubber or plastics scraper all the paste

46、adhering to the wall and bottom part of the bowl and place it in the middle of the bowl; d) restart the mixer and run at low speed for a further 90 s. The total mixer running time shall be 3 min. Any other mixing method may be used provided that it has been calibrated against the reference method. D
