20、aphy 5Page 3 EN 1015-4:1998 BSI 02-1999 Introduction Fresh mortar is brought to a defined level of consistence as measured using the plunger penetration rod prior to the assessment of those properties which are used to characterize it. Consistence is a measure of the fluidity and/or wetness of the f
21、resh 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 associated with the manner in which the fresh mortar handles when used by a craftsman. Normally there will be a linear correlation between the
22、plunger penetration value, measured according to this test method, and the flow value measured in accordance with prEN 1015-3, for the same type of mortar with increasing water content, but the slope will differ with different types of mortars. 1 Scope This European Standard specifies a method for d
23、etermining the consistence of freshly mixed mortars (in the following briefly referred to as fresh mortars) including those containing mineral binders and both dense and lightweight aggregates, which is by means of the plunger penetration value. 2 Normative references This European Standard incorpor
24、ates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this Europea
25、n Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 1015-2, Methods of test for mortar for masonry Part 2: Bulk sampling of mortars and preparation of test mortars. 3 Principle The plunger penetration
26、value of a defined sample of fresh mortar is measured by the vertical penetration of a defined plunger rod which has been allowed to fall freely through a given height into the fresh mortar sample. 4 Apparatus 4.1 Plunger apparatus, conforming to Figure 1, and consisting of the following parts: Plun
27、ger stand, with the base plate (A), frame, clamp with guide bushes (B) and fixing screw (C). Cylindrical vessel, (D) secured centrally in a positioning recess. Penetration rod, (E) with an upper scale and having a plastics plunger (F) of circular cross-section at the base and with a hemispherical lo
28、wer end of the same diameter. The total mass of the penetration rod and plunger is 90 g 2 g. The penetration rod is fixed in an initial position 100 mm above the mortar surface, measured from the lower, hemispherical end of the plunger. 4.2 Tamper, consisting of a rigid, non-absorptive rod of circul
29、ar 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. 4.3 Trowel. 4.4 Palette knife. 5 Sampling, preparation and storage of test samples The fresh mortar
30、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) 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 hy
31、draulic binders, shall be tested within their specified workable life. Mortars that are made from dry constituents and water shall 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
32、the mixer. Before testing, the batch shall be gently stirred by hand using a trowel (4.3) or palette knife (4.4)i n 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
33、tested. 6 Procedure Using the fixing screw 4.1(C), secure the penetration rod 4.1(E) in its initial position. Wipe the plunger 4.1(F) clean with a damp cloth and dry before use. Fill the vessel 4.1(D) with mortar in two layers, each layer being compacted by 10 short strokes of the tamper (4.2), to e
34、nsure uniform filling of the vessel. Skim off the excess mortar with a palette knife leaving the mortar surface plane and level with the top rim of the vessel. Do not trowel further. Place the filled vessel on the base plate 4.1(A) and release the fixing screw, allowing the plunger to fall freely, s
35、tarting from its initial position. Determine the penetration of the plunger into the mortar by reading the scale on the lower side of the upper guide bush 4.1(B) to the nearest mm.Page 4 EN 1015-4:1998 BSI 02-1999 1) This information is contained on the certificate of sampling (see EN 1015-2). 7 Cal
36、culation and expression of results Calculate the mean value of the plunger penetration from the individual values for each mortar test sample, to the nearest mm. If the two individual values deviate from their mean value by less than 10 % use this mean value as the plunger penetration value of the m
37、ortar. If the two individual plunger penetration 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 their mean value by less than 10 % use the mean value from the repeat test as
38、 the plunger penetration 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 informatio
39、n: a) the number, title and date of issue of this European Standard; b) the place, date and time of taking the bulk test sample 1) ; 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) an

41、asting, moulding, or demoulding procedure, if appropriate); g) the date and time of testing; h) test results (individual measurements and the plunger penetration values in mm for each test sample); i) remarks, if any.Page 5 EN 1015-4:1998 BSI 02-1999 Dimensions in millimetres Key: 1 Cylindrical vess
