Thi

16、s European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by December 2002. It has been prepared by sub-committee 8 “Products

17、and systems for the protection and repair of concrete structures“, the secretariat of which is held by AFNOR. This European Standard describes a method for determining the particle size distribution of repair mortars, containing various water-dispersible components. It has been adapted from EN 1015-

18、1 “Method of Test for mortar for masonry - Part 1: Determination of particle size distribution” which is unsuitable for measurement of particle size for proprietary repair products and systems because they contain a variety of special additives, fibres and fillers. It is one of a series of inter-rel

19、ated parts dealing with granulometry size grading of products and systems for the protection and repair of concrete structures. The other part of this standard is: EN 12192-2, Products and systems of the protection and repair of concrete structures Granulometry analysis Part 2: Test method for fille

20、rs for polymer bonding agents. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxe

22、 as defined in prEN 1504-3, with a maximum particle size of 8 mm or 10 mm. Part 1 does not cover particle size distribution of separate aggregates, which should be determined in accordance with the test method described in EN 933 series. NOTE This standard gives a method for granulometric analysis o

23、f fillers for polymer bonding agents. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

28、1 apply. 4 Principle Test sieves with increasing aperture size are nested on each other on top of a collection pan. The sample is placed on the top sieve and the stack of sieves agitated until the mass retained on each sieve remains constant. The retained mass is then measured. NOTE For samples with

29、 particles of different densities the sieve analysis will only give particle size distribution as a percent of total mass.1Under preparation.EN 12192-1:2002 (E) 5 5 Apparatus Table 1 Aperture sizes of the test sieves (in mm) Series A 1 2 8,00 4,00 2,00 1,00 0,500 0,250 0,125 0,063 1 Additional sieve

30、 aperture sizes (e.g. 5,6 mm, 0,09 mm) may be added when needed. 2 Series R20 from ISO 565 may be used as an alternative. 5.1 Balance with a capacity of 1 kg and an accuracy of 0,1 g. 5.2 Test sieves, with square apertures as specified in EN 933-2, are given in Table 1. The maximum aperture shall no

31、t exceed 10 mm. The test sieves shall conform to the requirements of ISO 3310-1. 5.3 Tightly fitting fines collection pan and lid, for the sieves. 5.4 Shallow trays, made of corrosion resistant metal, approximately 200 mm in diameter and 50 mm in height. 5.5 Soft brush. 5.6 Ventilated oven, thermost

32、atically controlled to maintain temperatures of (105 5) C and (60 5) C. 5.7 Sieving machine (optional). 6 Sampling and preparation The sample shall be taken in accordance with EN 1015-2. Reduction shall be carried out by use of a sample divider or by quartering, yielding a test sample of mass larger

33、 than minimum value below, but not of an exact predetermined value. The minimum dry mass of the test sample shall be as follows: 0,3 kg for D max 4 mm; 0,6 kg for D max 4 mm. where D max = the maximum aggregate size of the sample in millimetres. Spread the sample in a thin layer in shallow trays and

34、 dry in the oven at a temperature of (105 5) C. With respect to the special constituents of repair mortars, a drying temperature of (60 5) C may be used if recommended by the manufacturer.EN 12192-1:2002 (E) 6 Continue the drying process until two successive weighings of the sample at one day interv

35、als do not differ by more than 1 g. 7 Procedure 7.1 General If mortars with lightweight or organic aggregates are tested, the material to be sieved may be statically charged by the motion of the material on the sieve, resulting in agglomeration, or sticking to the sieve base. Should such a phenomeno

36、n occur, suitable measures should be taken to reduce this effect. 7.2 Sieving The dried sample shall be weighed immediately before sieving. The sample shall be placed on the top sieve of the nested sieves and the sieve-shaking procedure begun. NOTE Mechanical sieving is preferred, but manual sieving

37、 can be used if it produces the same results as mechanical sieving. Continue sieving until less than 1 % of the retained material (according to EN 933-1) will pass through any individual sieve during continuous hand sieving for one minute. Do not force any material through the sieve by hand pressure

38、. The use of a soft brush may be helpful if the mortar agglomerates. 7.3 Weighing Determine the mass of each fraction retained on the individual sieves and the fines collected in the pan. By addition, calculate the residual mass of the sample. Any difference between the original weight and the resid

39、ual weight shall be added to the pan fines. NOTE 1 Some losses of very fine material into the air are likely to occur. On the sieves with apertures smaller than 4,00 mm, the fraction retained at the end of the sieving operation shall not exceed the following: 200 r d A = m where m r is the mass, in

40、grams of the fraction retained on the sieve; A is the area, in square millimetres, of the sieve; d is the nominal aperture size, in millimetres, of the sieve. If any of the fractions retained exceeds this amount, one of the two following procedures shall be used: a) divide the fraction into proporti

41、ons smaller than the specified maximum and sieve these one after the other; b) divide the portion of the sample passing through the 4,00 mm sieve with the aid of a sample divider or by quartering, and continue the sieve analysis on the reduced sample. NOTE 2 To meet these requirements, completing th

42、e mechanical sieving by hand may be necessary. If the material to be sieved contains fibres, their proportion and type shall be recorded and described.EN 12192-1:2002 (E) 7 8 Expression of results Calculate each individual retained fraction as percentage of the total mass of the sample, and express

43、this as the percentage passing each sieve. If a dividing operation as described in 7.3 was carried out, this shall be taken into account in the calculation. NOTE A graphical presentation of the results can assist in making comparisons with manufacturers production limits. 9 Test Report The test repo

44、rt shall include the following information: a) a reference to the test method standard; b) name and address of the test laboratory; c) identification number and date of the test; d) name and address of the manufacturer or supplier of the product; e) name and identification marks or batch number of t

45、he product; f) date of supply of the product; g) date of preparation of the test specimens and any deviation from the prescribed method of preparation; h) conditions of storage of prepared specimens prior to test; i) date of test and details of the test equipment used, including the make, type and c

47、of the total sample passing each sieve, to the nearest 1 %; k) if fibres are present, description of procedures used to identify nature and measure fibre content; l) precision data; m) date of test report and signature.BS EN 12192-1:2002 BSI 389 Chiswick High Road London W4 4AL BSI British Standards
