23、n a prescribed manner into a measuring vessel of a given capacity. 4 Symbols mis the bulk density of fresh mortar in, (kg/m3) m1is the mass of the empty vessel, (g) m2is the mass of the vessel filled with mortar, (g) Vvis the volume of measuring vessel, (l) 5 Apparatus 5.1 A measuring vessel compris

24、ing a cylindrical bowl with an internal diameter of about 125 mm, made of metal resistant to corrosion by mortar and with sufficient dimensional stability. The capacity of the measuring vessel is approximately 1 l and determined with an accuracy of 0,1 %, and its mass m1determined with an accuracy o

25、f 1 g. NOTE It is advisable to use the same measuring vessel by which the air content of the fresh mortar is determined (see EN 1015-7). 5.2 A palette knife. 5.3 A trowel. 5.4 A scoop. 5.5 A vibrating table, if necessary, operating in vertical direction with a frequency of 50 Hz 1 Hz and amplitude 0

26、,375 mm 0,050 mm. 5.6 A weighing instrument with a capacity of at least 5 kg and an accuracy of 1 g. 6 Sampling, preparation and storage of test samples The fresh mortar for this test shall have a minimum volume of 3 l or at least 1,5 times the quantity needed to perform the test, whichever is the g

27、reater, and shall either be obtained by reduction of the bulk test sample (see EN 1015-2) using a sample divider or by quartering or by preparation from dry constituents and water in the laboratory. The flow value of the mortar in the bulk test sample shall be determined in accordance with EN 1015-3

28、 and reported. Laboratory mixed test samples shall, before testing, be brought to a defined flow value as specified in EN 1015-2. Ready to use mortars (factory-made wet mortars which are retarded), and pre-batched air-lime/sand wet mortars when not gauged with hydraulic binders, shall be tested with

29、in their specified workable life. The length of mixing period shall be measured from the moment all the constituents are introduced into the mixer. EN 1015-6:1998 + A1:2006 (E) 5 Before testing, the batch shall be gently stirred by hand using a trowel (5.3) or palette knife (5.2) for 510 seconds to

30、counteract any false setting etc., but without any additional mixing of the batch. Any deviation from the mixing procedure shall be noted. Two test samples shall be tested. 7 Procedure 7.1 General Determine the bulk density of laboratory-mixed test samples with a defined flow value achieved, as spec

31、ified in Clause 6, in accordance with 7.2.2 unless otherwise specified by the manufacturer. Determine the bulk density of bulk test samples as specified in Table 1 dependent on their consistence in use, observing instructions given by the manufacturer where appropriate. NOTE When testing mortars con

32、taining air entraining agents, care should be taken to ensure that the procedure will not influence the air content. Table 1 Procedures for the determination of the bulk density of mortars Consistence in use Flow value mm Procedure Stiff mortar 200 mm Test the mortar in accordance with 7.2.3 7.2 Fil

33、ling and compaction 7.2.1 Filling and compaction by the vibration method Fill the measuring vessel (5.1) with the mortar by means of the scoop (5.4) until the mortar projects above the vessel. Place the vessel on a vibrating table (5.5) as described in Clause 5 and vibrate until no further settling

34、can be observed. During the vibration, add further mortar until it projects above the vessel again. Using the palette knife, skim off any excess mortar leaving the mortar surface plane and level with the top edge of the vessel. Wipe the edge clean with a damp cloth. 7.2.2 Filling and compaction by t

35、he shock method Fill the measuring vessel with the mortar by means of the scoop up to about half the height. For compaction of the mortar, tilt the vessel about 30 mm on alternate sides and allow to fall a total of 10 times onto a solid, rigid substrate with a mass of not less than 25 kg. Then fill

36、the measuring vessel with further mortar to the top edge and compact the mortar in the same manner. Subsequently add mortar till it projects above the edge. Using the palette knife, skim off any excess mortar leaving the mortar surface plane and level with the top edge of the vessel. Wipe the edge c

37、lean with a damp cloth. EN 1015-6:1998 + A1:2006 (E) 6 7.2.3 Filling method Fill the measuring vessel with the mortar by means of the scoop in such a way that the mortar flows from the centre of the vessel to its outer surface1). Add mortar till it projects above the edge. Using the palette knife, s

38、kim off any excess mortar leaving the mortar surface plane and level with the top edge of the vessel. Wipe the edge clean with a damp cloth. 7.2.4 Weighing Determine the total mass m2of the vessel filled with mortar to the nearest 1 gram. 8 Calculation and expression of results Calculate the bulk de

39、nsity of fresh mortar (m) from the following: v12mVmm = Calculate the mean value of the two measurements rounded to the nearest 10 kg/m3. If the individual values from the two test samples deviate from their mean value by less than 10 %, use this mean value as the bulk density of the mortar. If the

40、two individual values deviate from their mean value by more than 10 %, repeat the test using further mortar from the reduced bulk test sample (see Clause 6) and if the results deviate from their mean value by less than 10 % use the mean value from the repeat test as the bulk density of the mortar. I

41、f the results deviate by more than 10 % consider the measurements unsatisfactory and take fresh test samples from the bulk test sample or laboratory prepared mortar and repeat the test. 9 Test report The test report shall include the following information: a) the number, title and date of issue of t

43、the type, origin and designation of the mortar by reference to the relevant part of EN 998; e) the date and time of testing; f) preparation (mixing, casting) and storage (curing) conditions; g) the date and time of preparing test samples for test (i.e. date and time of any mixing, casting, moulding,
