BSI 2007Page 3 EN 1015-1:1998 1 Scope This European Standard specifies two methods of determining the particle size distribution of dry mixed or non-hardened wet mixed mortars. The method of wet sieving is applicable to mortars containing norma
20、l weight aggregates and the method of dry sieving to mortars containing lightweight aggregates. This European Standard does not cover particle size distribution of separate aggregates, which should be determined in accordance with the test method described in European Standard EN 933, nor does it co
21、ver mixes containing fibres which cannot be removed before sieving. 2 Normative references 998-1, Specification for mortar for masonry Part 1: Rendering and plastering mortar with inorganic binding agents. 998-2, Specification for mortar for masonry Part 2: Masonry mortar. EN 1015-2, Methods of test
22、 for mortar for masonry Part 2: Bulk sampling of mortars and preparation of test mortars. 3 Principle A series of test sieves (5.2) with increasing aperture size are nested on top of one another on a bottom pan. The sample is placed on the top sieve and the stack of sieves is then agitated until fur
23、ther agitation causes no change in the mass retained on each sieve, which is weighed. NOTE For samples with particles of different densities the sieve analysis will only give the particle size distribution in % of total mass. 4 Symbols m r is the mass of the fraction retained on the sieve (g); A is
24、the area of the sieve (mm 2 ); d is the nominal aperture size of the sieve (mm); d max is the maximum aggregate size of the sample in (mm). 5 Apparatus 5.1 Weighing instrument, with a capacity of 1 kg capable of weighing to an accuracy of 0,1 g. 5.2 Test sieves, with square apertures, conforming to
25、Table 1. NOTE For aperture sizes of 4,00 mm and above perforated plate sieves are recommended.

26、on-resistant metal, approximately 200 mm in diameter and 50 mm in height. 5.6 Containers, suitable for holding fresh mortar samples to which water can be added for the creation of a suspension. 5.7 A ventilated oven, capable of maintaining temperatures of 1058C 58C and 608C 58C respectively. 6 Prepa
27、ration and storage of test samples from the bulk test sample The bulk test sample taken in accordance with EN 1015-2 shall be reduced using a sample divider or by quartering, and shall yield a test sample of mass larger than the minimum, but not of an exact predetermined value. The minimum dry mass
28、of the test sample shall be as follows: 0,2 kg for d max # 4 mm; 0,6 kg for d max 4 mm. Mortars containing particles passing aperture size 0,125 mm may be wetted before reduction to minimize segregation and loss of dust. If the sample contains hydraulic binders, the following preparation under wet c
29、onditions shall be executed as quickly as possible. If dry sieving is required, the wetting of mortars containing hydraulic binders shall be omitted. If the material to be sieved contains fibres, these shall be removed prior to sieving and be considered as not belonging to the material to be sieved.
30、 Their proportion and type shall be recorded and described. If removal is not possible, then sieving in accordance with this European Standard is not applicable.EN EN! “ “ !

32、or organic aggregates may become statically charged by the motion of the material on the sieve, resulting in agglomeration, or sticking to the sieve base. Should such a phenomenon occur, suitable measures should be taken. 7.2 Wet sieving Place the test sample in a container (5.6) and cover it with w
33、ater. Mix the suspension up quickly, and pour it with the wash water on the nested sieves (5.2). Carry out sieving with the aid of a water jet until the wash water remains clean. Remove the fraction retained on each sieve and from the pan and spread each fraction in a thin layer into separate shallo
34、w trays (5.5). Dry each in the oven at a temperature of 1058C 58C. Continue the drying process until two consecutive weighings of each fraction at 2 h intervals do not differ by more than 0,2 g. 7.3 Dry sieving Spread the sample in a thin layer in shallow trays (5.5) and dry in the oven (5.7) at a t
35、emperature of 1058C 58C. For samples with organic constituents, e.g. expanded polystyrene aggregate or exfoliated vermiculite, use a drying temperature of 608C 58C. Continue the drying process until two consecutive weighings of the sample at 2 h intervals do not differ by more than 0,2 g. Place the
36、dried sample on the nested sieves and carry out sieving until it is ascertained that less than 0,2 % of the total sample mass will pass any individual sieve during continuous hand sieving for 1 min. Do not force any material through the sieve. 7.4 Weighing Determine the mass of each fraction (m r )
37、retained on the individual sieves and sum them to give the mass of the total sample. The difference between the total and the sample weight is the amount of fine particles. On sieves with apertures smaller than 4,00 mm, the mass of each fraction retained at the end of the sieving operation shall not
38、 exceed: m r = A d 200 If any of the mass fractions retained exceeds this amount, use one of the two following procedures: a) divide the fraction into portions smaller than the specified maximum and sieve these one after the other; or b) divide the portion of the sample passing the 4,00 mm sieve wit
39、h the aid of a sample divider or by quartering, and continue the sieve analysis on the reduced sample. 8 Calculation and expression of results Calculate the individual fractions, as percentages of the total mass of the sample, and calculate the total percentage of material passing each sieve. If a d
40、ividing operation as described in 7.4 was performed, take this into account in the calculation. 9 Test report The test report shall include the following information: 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) ; NOT
