3、reword This standard has been prepared by CEN/TC 125. The responsible German body involved in its preparation was the Normenausschu Bauwesen (Building and Civil Engineering Standards Committee), Technical Committee Mauerwerksbau. This European Standard is part of a series of standards dealing with m

4、ortar for masonry within the scope of the EC Directive on the approximation of the laws, regulations and administrative provisions of the Member States relating to construction products. It should be noted that not all of the DIN Standards dealing with mortar for masonry need yet be withdrawn. This

5、is in keeping with resolution 22/97 taken by CEN/BTSl, which states that where packages of EN Standards are concerned, it shall be permitted for the relevant national standards to remain valid for longer periods than usual, until the EN package has been published in its entirety. In the case at hand

6、, all of the relevant EN Standards have not yet been published, and CEN/TC 125 has therefore decided to extend the period of validity for relevant national standards until the end of September 2000.

This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Fr

Page 3 EN 1 O1 5-4 : 1998 Introduction Fresh mortar is brought to a dened level of consistence as measured using the plunger pene

19、tration rod prior to the assessment of those properties which are used to characterise it. Consistence is a measure of the fluidity andor 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 no

20、t 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 plunger penetration value, measured according to this test method, and the flow value measured in accordance with prEN 1015-3, for the same type o

21、f mortar with increasing water content, but the slope will differ with different type of mortars. 1 Scope This European Standard specifies a method for determinuig the consistence of freshly mixed mortars (in the following briefly referred to as fresh mortars) including those containing mineral bind

22、ers and both dense and lightweight aggregates, whch is by means of the plunger penetration value. 2 Normative references This European Standard incorporates by dated or undated reference, provisions fi-om other publications. These normative references are cited at the appropriate places in the tex3

23、and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

24、 EN 1 O 15-2 Methods of test for mortar for masonry - Part 2 : Bulk sampling of mortars and preparation of test mortars. 3 Principle The plunger penetration 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 freel

25、y through a given height into the fresh mortar sample. 4 Apparatus 4.1 A plunger apparatus conforming to figure 1, and consisting of the following parts: Plunger stand with the base plate (A), frame, clamp with guide bushes (B) and fixing screw (C) Cylindrical vessel (D) secured centrally in a posit

26、ioning 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 lower end of the same diameter. The total mass of the penetration rod and plunger is 90 g f 2 g. The penetration rod is fixed in an initial position

27、 100 mrn above the mortar surface, measured from the lower, hemispherical end of the plunger. 4.2 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

28、 the tamper. The mass of the tamper is 0:250 kg h 0,015 kg. Page 4 EN 1 O1 5-4 : 1998 4.3 A trowel 4.4 A palette knife 5 Sampling, preparation and storage of test samples The fresh mortar for this test shall have a minimum volume of 1,5 1 and shall be obtained by reduction of the bulk test sample (s

29、ee 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 hydraulic binders, shall be tested within their specified workable life. Mortars that are made from dry constituen

30、ts 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 the mixer. Before testing, the batch shall be gently stirred by hand using a trowel (4.3) or palette knife (4.4)

31、 in 5 -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. 6 Procedure Using the fixing screw (4.1(C), secure the penetration rod (4.1(E) in its initial position. Wi

32、pe 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 ensure uniform filling of the vessel. Skim off the excess mortar with a palette knife leaving the mortar surfac

33、e 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, starting from its initial position. Determine the penetration of the plunger into the mortar by reading the sc

34、ale on the lower side of the upper guide bush (4.1 (B) to the nearest mm. 7 Calculation 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

35、by less than 10% use this mean value as the plunger penetration value of the mortar. 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 buk test sample (see Clause 5) and if the results deviate from

36、their mean value by less than 10% use the mean value from the repeat test as 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

37、 test.
