16、of which is held by DIN. This 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of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by December 2002.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 b
17、y sub-committee 8 ”Products 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 ha
18、s been adapted from EN 1015-1 ”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
19、 one of a series of inter-related parts dealing with granulometry size grading of products and systems for the protection and repair of concrete structures.

21、, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 12192-1 :2002 (E) 1 Scope This European Standard specifies a method for measuring the particle size distribution of the dry components of repair mortar mixes, being pa
22、rt of a repair product or system, 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 me
23、thod for granulometric analysis of fillers for polymer bonding agents. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

28、nd definitions contained in EN 1504-1 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
29、then measured. NOTE of total mass. For samples with particles of different densities the sieve analysis will only give particle size distribution as a percent Under preparation. 4 EN 12192-1 :2002 (E) 5 Apparatus Table 1 -Aperture sizes of the test sieves (in mm) Series Al 8,OO 4,OO 2,oo 1 ,o0 I 0,5
30、00 I I 0,250 I O, 125 I 0,063 I Additional sieve aperture sizes (e.g. 5,6 mm, 0,09 mm) may be added when needed. Series R20 from IS0 565 may be used as an alternative. 5.1 Balance with a capacity of 1 kg and an accuracy of 0,l g. 5.2 shall not exceed 10 mm. The test sieves shall conform to the requi
31、rements of IS0 3310-1. Test sieves, with square apertures as specified in EN 933-2, are given in Table 1. The maximum aperture 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.
32、 5.5 Soft brush. 5.6 Ventilated oven, thermostatically controlled to maintain temperatures of (105 f 5) OC and (60 f 5) OC. 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
33、by quartering, yielding a test sample of mass larger 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 Dmax 2 4 mm; 0,6 kg for Dmax 4 mm. where Dmax = the maximum aggregate size of the sample in millimetres. Spr
34、ead the sample in a thin layer in shallow trays and dry in the oven at a temperature of (105 f 5) OC. With respect to the special constituents of repair mortars, a drying temperature of (60 f 5) OC may be used if recommended by the manufacturer. 5 EN 12192-1 :2002 (E) Continue the drying process unt
35、il two successive weighings of the sample at one day intervals 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 agglomerat
36、ion, or sticking to the sieve base. Should such a phenomenon 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 begu
37、n. NOTE sieving . Mechanical sieving is preferred, but manual sieving can be used if it produces the same results as mechanical 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.
38、Do not force any material through the sieve by hand pressure. 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 samp
39、le. Any difference between the original weight and the residual 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,OO mm, the fraction retained at the end of the sieving operation shall not ex
40、ceed the following: where m, is the mass, in 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
41、be used: a) divide the fraction into proportions smaller than the specified maximum and sieve these one after the other; b) divide the portion of the sample passing through the 4,OO mm sieve with the aid of a sample divider or by quartering, and continue the sieve analysis on the reduced sample. NOT
42、E 2 To meet these requirements, completing the mechanical sieving by hand may be necessary. If the material to be sieved contains fibres, their proportion and type shall be recorded and described 6 EN 12192-1 :2002 (E) 8 Expression of results Calculate each individual retained fraction as percentage
43、 of the total mass of the sample, and express 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
44、production limits. 9 TestReport The test report shall include the following information: a reference to the test method standard; name and address of the test laboratory; identification number and date of the test; name and address of the manufacturer or supplier of the product; name and identificat
