21、 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 plastering mortar with inorganic binding agents. 998-2,Specification for mo

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 consistence of fresh mortar (by flow table). 3 Principle The bulk densit
23、y 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 rmis the bulk density of fresh mortar in (kg/m3); m1is the mass of the empty
24、 vessel (g); m2is the mass of the vessel filled with mortar (g); Vvis 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 metal resistant to corrosion by mortar and with sufficient dimensional stabilit
25、y. 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 of 1 g. NOTEIt is advisable to use the same measuring vessel by which the air content of the fresh mortar is determined (see EN 1015-7). 5.5 Vibrating tab

27、m 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 quartering or by preparation from dry constituents and water in the laboratory. The
28、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 mortars (factory-made wet mortars which are retarded), and pre-batched air-lime/sand
29、 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 mixer. Before testing, the batch shall be gently stirred by hand using a trowel (5.3)
30、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 tested. 7 Procedure 7.1 General Determine the bulk density of laboratory-mixed test sampl
31、es 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 dependent on their consistence in use, observing instructions given by the manufacturer wh
32、ere appropriate. NOTEWhen testing mortars containing air entraining agents, care should be taken to ensure that the procedure will not influence the air content.

35、information is contained on the certificate of sampling (see EN 1015-2). 7.2 Filling 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 vibra
36、ting table (5.5) as described in clause 5 and vibrate 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
37、vessel. Wipe the edge clean with a damp cloth. 7.2.2 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
38、 excess mortar leaving the mortar surface plane and level with the top edge of the vessel. Wipe the edge clean with a damp cloth. 7.2.3 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 surfac

If the individual values from the two test samples deviate from their mean value by l
41、ess than 10 %, use this mean value 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 %
42、 use the mean value from the repeat 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 i
