19、 3 EN 1015-6:1998 1 Scope This European Standard specifies a method for determining the bulk density of fresh mortars including those containing mineral binders and both dense and lightweight aggregates. 2 Normative references 998-1, Specification for mortar for masonry Part 1: Rendering and plaster
20、ing mortar with inorganic binding agents. 998-2, Specification for mortar for masonry Part 2: Masonry mortar. EN 1015-2, Methods of test for mortar for masonry Part 2: Bulk sampling of mortars and preparation of test mortars. 1015-3, Methods of test for mortar for masonry Part 3: Determination of co
21、nsistence of fresh mortar (by flow table). 3 Principle The bulk density of a fresh mortar is determined by the quotient of its mass and the volume which it occupies when it is introduced, or introduced and compacted in a prescribed manner into a measuring vessel of a given capacity. 4 Symbols r m is
22、 the bulk density of fresh mortar in (kg/m 3 ); m 1 is the mass of the empty vessel (g); m 2 is the mass of the vessel filled with mortar (g); V v is the volume of measuring vessel (l). 5 Apparatus 5.1 Measuring vessel, comprising a cylindrical bowl with an internal diameter of about 125 mm, made of
23、 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 m 1 determined with an accuracy of 1 g. NOTE It is advisable to use the same measuring vessel by which t
24、he air content of the fresh mortar is determined (see EN 1015-7). 5.5 Vibrating table, if necessary, operating in the vertical direction with a frequency of 50 Hz 1 Hz and amplitude 0,375 mm 0,050 mm. 5.6 Weighing instrument, with a capacity of at least 5 kg and an accuracy of 1 g. 6 Sampling, prepa
25、ration and storage of test samples The fresh mortar for this test shall have a minimum volume of 3 1 or at least 1,5 times the quantity needed to perform the test, whichever is the greater, and shall either be obtained by reduction of the bulk test sample (see EN 1015-2) using a sample divider or by
26、 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 Laboratory mixed test samples shall, before testing, be brought to a defined flow value as specified in EN 1015-2. Ready to use
27、 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 within their specified workable life. The length of mixing period shall be measured from the moment all the constituents are introduced into the m
28、ixer. Before testing, the batch shall be gently stirred by hand using a trowel (5.3) or palette knife (5.2) for 5 to 10 seconds to 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 test
29、ed. 7 Procedure 7.1 General Determine the bulk density of laboratory-mixed test samples with a defined flow value achieved, as specified 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 depen
30、dent on their consistence in use, observing instructions given by the manufacturer where appropriate. NOTE When testing mortars containing air entraining agents, care should be taken to ensure that the procedure will not influence the air content. BSI 2007 5.2 Palette knife. 5.3 Trowel. 5.4 Scoop. E

Place the vessel on a vibrating table (5.5) as described in clause 5 and vib
34、rate until no further settling 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.
35、2.2 Filling and compaction by the shock method Then fill 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 a
36、nd level with the top edge of the vessel. Wipe the edge clean with a damp cloth. 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 surface 1) . Add mortar till it projects above the edge
37、. 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. 7.2.4 Weighing Determine the total mass m 2 of the vessel filled with mortar to the nearest 1 g. 8 Calculation and expression of re
38、sults Calculate the bulk density of fresh mortar (r m ) from the following: r m = m 2 2 m 1 V v Calculate the mean value of the two measurements rounded to the nearest 10 kg/m 3 . If the individual values from the two test samples deviate from their mean value by less than 10 %, use this mean value
39、as the bulk density of the mortar. If the 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
40、 test as the bulk density of the mortar. If 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
