Introduction Fresh mortar is brought to a defined level of consistence as measured using the flow table prior to the assessment of those properties

24、which are used to characterise it. EN 1015-3:1999 + A1:2004 + A2:2006 (E) 4 Consistence is a measure of the fluidity and/or wetness of the fresh mortar and gives a measure of the deformability of the fresh mortar when subjected to a certain type of stress. The consistence however is not directly ass

25、ociated with the manner in which the fresh mortar handles when used by a craftsman. Normally there will be a linear correlation between flow value, measured in accordance with this test method, and the plunger penetration value measured in accordance with EN 1015-4, for the same type of mortar with

26、increasing water content, but the slope will differ with different type of mortars. 1 Scope This European Standard specifies a method for determining the consistence of freshly mixed mortars (in the following briefly referred to as fresh mortars) including those containing mineral binders and both n

27、ormal weight and lightweight aggregates, which is by means of the flow value. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the refe

28、renced document (including any amendments) applies.

29、pling of mortars and preparation of test mortars 3 Principle The flow value is measured by the mean diameter of a test sample of the fresh mortar which has been placed on a defined flow table disc by means of a defined mould, and given a number of vertical impacts by raising the flow table and allow

30、ing it to fall freely through a given height. 4 Apparatus 4.1 A flow table, as described in annex A, consisting of the following main parts: stand rigid table plate and disc horizontal shaft and lifting cam lifting spindle 4.2 A truncated conical mould made of stainless steel or brass, 60 mm 0,5 mm

31、in height and with internal diameter of 100 mm 0,5 mm at the bottom and 70 mm 0,5 mm at the top. The inside surface and the edges of the mould are smooth. The planes containing the top and bottom edges are at right angles to its axis. The minimum thickness of the mould wall is 2,0 mm. EN 1015-3:1999

32、 + A1:2004 + A2:2006 (E) 5 4.3 A tamper consisting of a rigid, non-absorptive rod of circular cross-section, approximately 40 mm in diameter and approximately 200 mm long. The tamping face is flat and at right angles to the length of the tamper. The mass of the tamper is 0,250 kg 0,015 kg. 4.4 Calip

33、ers capable of measuring diameters up to 300 mm with an accuracy of 1 mm. 4.5 Trowel. 4.6 Palette knife. 5 Sampling, preparation and storage of test samples The fresh mortar for this test shall have a minimum volume of 1,5 l and shall be obtained by reduction of the bulk test sample (see EN 1015-2)

34、using a sample divider or by quartering. 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 within their specified workable life. Mortars that are made from dry constituents and water s

35、hall be mixed in accordance with EN 1015-2 unless otherwise specified. 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 or palette knife in 510 seconds to counter

36、act 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. 6 Procedure Before each test, wipe the disc and the inner surface and edges of the mould (4.2) clean with a damp cloth and let it dry.

37、 If the table has not been used within the last 24 h, operate for ten revolutions before use. Place the mould centrally on the disc of the flow table (4.1) and introduce the mortar in two layers, each layer being compacted by at least 10 short strokes of the tamper (4.3) to ensure uniform filling of

38、 the mould. During filling, hold the mould firmly on the disc, using one hand. Skim off the excess mortar with a palette knife and wipe the free area of disc clean and dry, being especially careful to remove any water from around the bottom edge of the mould. After approximately 15 s, slowly raise t

39、he mould vertically and spread out the mortar on the disc by jolting the flow table 15 times at a constant frequency of approximately one per second. Measure the diameter of the mortar in two directions at right angles to one another using calipers (4.4). State the results in mm to the nearest mm. 7

40、 Calculation and expression of results Calculate the mean value of the two measurements. This mean value is the flow value for the test sample. If the individual flow values from the two test samples deviate from their mean value by less than 10 %, use this mean value as the flow value of the mortar

41、. If the two individual flow values deviate from their mean value by more than 10 %, repeat the test using further mortar from the reduced bulk test sample (see Clause 5) and if the results deviate from the mean value by less than 10 % use the mean value from the repeat test as the flow EN 1015-3:19

42、99 + A1:2004 + A2:2006 (E) 6 value of the mortar. If the results differ 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. 8 Test report The test report shall include the following inform

43、ation : a) the number, title and date of issue of this European Standard; b) the place, date and time of taking the bulk test sample1); NOTE This is the sample taken from the bulk supply that is to be used for all of the tests in EN 1015. c) the method used for taking the bulk test sample (if known)

44、 and the name of the organization that took it; d) the type, origin and designation of the mortar by reference to the relevant part of EN 998; e) preparation (mixing, casting) and storage (curing) conditions; f) the date and time of preparing test samples for test (i.e. date and time of any mixing,

45、casting, moulding, or demoulding procedure, if appropriate); g) the date and time of testing; h) test results (individual measurements and the flow values in mm for each test sample) i) remarks, if any. 1) This information is contained on the certificate of sampling (see EN 1015-2).

The stand for the flow table shall be made of steel or cast iron. The flow table shall be mounted without any other support directly on a horizontal,

47、non sprung and non plastic, stable base. NOTE 1 A concrete pedestal with a mass of more than 25 kg is suitable. The horizontal shaft with the mounted lifting cam when turned at a constant velocity shall raise the lifting spindle and the flow table by 10 mm/s 0,2 mm/s. The lifting cam shall be an eve

48、n steady rising spiral constructed such that it will resume permanent contact with the lifting spindle from 120 after the impact has occurred and through the following 240 rotation up to the next impact. The vertical lifting spindle shall be fastened at top in the middle of a rigid table plate. Both

49、 of these shall be made of steel or cast iron. The lifting spindle shall be stabilised by bearings spaced minimum 60 mm vertical in the stand, the bearings having a tolerance in diameter of 0,05 mm to 0,1 mm. NOTE 2 The contact faces of the lower end of the lifting spindle and of the lifting cam should be constructed to ensure long term performance. A rotatable roller in the lower end of the lifting spindle is suitable. The edge of the lifting cam and the lower end of the lifting spindle may alternatively be hardened to a Brine
