20、particle size distribution of dry mixed or non hardened wet mixed mortars. The method of wet sieving is applicable to mortars containing normal weight aggregates and the method of dry sieving to mortars containing lightweight aggregates. This European standard does not cover particle size distributi
21、on of separate aggregates which should be determined in accordance with the test method described in European Standard EN 933, nor does it cover mixes containing fibres which cannot be removed before sieving. 2 Normative references The following referenced documents are indispensable for the applica
22、tion of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

24、n 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 further 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
25、 the particle size distribution in % of total mass. 4 Symbols mris the mass of the fraction retained on the sieve, (g); A is the area of the sieve (mm2); d is the nominal aperture size of the sieve, (mm); dmaxis the maximum aggregate size of the sample, in (mm). 5 Apparatus 5.1 Weighing instrument w
26、ith a capacity of 1 kg capable of weighing to an accuracy of 0,1 g . 5.2 Test sieves, with square apertures, conforming with Table 1. NOTE For aperture sizes of 4,00 mm and above, perforated plate sieves are recommended. 5.3 Mechanical sieve shaker. Table 1 Test sieve aperture sizes Aperture sizes m

EN 1015-1:1998 + A1:2006 (E) 5 5.5 Shallow trays, made of corrosion-resistant metal, approximately 200 mm in diameter and 50 mm in height. 5.6 Containers, suitable for holding fresh mortar samples to which wa
28、ter can be added for creation of a suspension. 5.7 A ventilated oven, capable of maintaining a temperatures of 105 C 5 C and 60 C 5 C respectively. 6 Preparation 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 sam
29、ple 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 of the test sample shall be as follows: 0,2 kg for dmax 4 mm 0,6 kg for dmax 4 mm Mortars containing particles passing aperture size 0,125 mm, ma
30、y be wetted before reduction to minimize segregation and loss of dust. If the sample contains hydraulic binders, the following preparation under wet condition shall be executed as quickly as possible. If dry sieving is required, the wetting of mortars containing hydraulic binders shall be omitted. I
31、f 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. Their proportion and type shall be recorded and described. If removal is not possible, then sieving in accordance with this European standard is not a
32、pplicable. 7 Procedure 7.1 General Mortars shall be tested by dry sieving unless it is anticipated that they may contain agglomerates, when wet sieving shall be used. NOTE Mortars containing lightweight or organic aggregates may become statically charged by the motion of the material on the sieve, r
33、esulting 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 water. Mix the suspension up quickly, and pour it with the wash water on the nested sieves (5.2).
34、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 shallow trays (5.5). Dry each in the oven at a temperature of 105 C 5 C. Continue the drying process un
35、til 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 temperature of 105 C 5 C. For samples with organic constituents, e.g. expanded polystyrene aggrega
36、te or exfoliated vermiculite, use a drying temperature of 60 C 5 C. Continue the drying process until two consecutive weighings of the sample at 2 h intervals do not differ by more than 0,2 g. EN 1015-1:1998 + A1:2006 (E) 6 Place the dried sample on the nested sieves and carry out sieving until it i
37、s 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 (mr) retained on the individual sieves and sum them to give the mass of t
38、he 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 exceed: 200rdAm = If any of the mass fractions retained exceeds thi
39、s 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 with the aid of a sample divider or by quartering, and continue the sieve a
40、nalysis 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 dividing operation as described in 7.4 was performed, take this into acco
41、unt 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 sample1); NOTE This is the sample taken from the bulk supply that is to be used for al
