DIN EN 13041:2012-01 EN 13041:2011 (E) 4 1 Scope This European Standard describes an instrumental method for the routine determination of the physical properties, dry bulk density, water volume, air volume, shrinkage value and total pore space of soil improvers or grow

29、ing media. This European Standard is not suitable for those materials which are very coarse, which do not make proper capillary contact or those which are pre-formed and non-particulate and have closed porosity. It is applicable to materials with particles 25 mm and/or flexible fibres 80 mm. This me

30、thod is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs. NOTE The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned. 2 Normative references The following referenced documents

35、 value loss in volume of the sample after drying a moist sample 3.5 water volume that part of the volume of a sample filled by water measured under the conditions specified in this European Standard, in particular at a defined suction (e.g. 10 cm water = 1 kPa suction) DIN EN 13041:2012-01 EN 13041:

36、2011 (E) 5 3.6 particle density the ratio of the total mass of oven-dry solid particles (minerals, organic matter) to the volume of these particles. The volume of the internal pores of the particles and the pore spaces between particles are excluded 4 Principle The sample is saturated in water and t

37、hen equilibrated on a sand box at 50 cm water (5 kPa) pressure head. The sample is then transferred into double ring sample cylinders, re-wetted and equilibrated at minus 10 cm water (1 kPa) pressure head. After equilibration the physical properties are calculated from the wet and dry weights of the

38、 sample in the lower ring. After 10 cm water pressure head (= 1 kPa) it is optional also to apply 50 cm and 100 cm water (5 kPa and 10 kPa) pressure head respectively. 5 Apparatus 5.1 Double rings (see Figure A.1) 5.1.1 General The double rings and fixing collars described in this clause, shall be m

39、ade from any rigid material that will not deform at a temperature of up to 120 C. 5.1.2 Lower sample ring 5.1.2.1 Sample ring of internal diameter (D1) (100 1) mm and height (50 1) mm. As each ring is individually made it is necessary to determine the volume (V1), record the mass (m1) and identify e

40、ach lower sample ring. The volume shall be determined by measuring the mean height (at least quadruplicate measurements) (h1) and mean diameter (d1) of the sample rings with a calliper gauge (At least triplicate measurements; top, middle and bottom). 5.1.2.2 Removable gauze-retaining ring or collar

41、20 mm high and 7,5 mm to 8,5 mm larger than the outer diameter of the sample ring. 5.1.2.3 Non-biodegradable synthetic gauze with a mesh size of about 0,1 mm. 5.1.3 Upper ring 5.1.3.1 Upper ring having the same internal diameter as the ring prepared in (see 5.1.2.1) and height (53 1) mm. 5.1.3.2 Col

42、lar - fixed on the ring permitting the upper cylinder to be secured to the lower cylinder for the duration of the test. 5.2 Plastic tube, of approximately 14 cm diameter and 14 cm high to give a volume of about 2 l. Tightly stretch and secure the gauze (see 5.1.2.3) to one end of the tube by means o

43、f an elastic band. 5.3 Water bath, capable of holding at least 4 plastic tubes (see 5.2) standing on a coarse mesh and capable of being filled with water to the top of the plastic tubes. 5.4 Sand suction table (see Figure A.3) Prepare the sand suction table for example in accordance with Annex A, us

44、ing the fine sand to obtain the required suction. The pressure head in the plastic tubes (50 cm water = 5 kPa) is measured from the DIN EN 13041:2012-01 EN 13041:2011 (E) 6 bottom of the tube. The pressure head in the rings (10 cm, 50 cm and 100 cm water, equivalent to 1 kPa, 5 kPa and 10 kPa, respe

45、ctively) is measured from the middle of the lower ring (see Figure A.3). The setting of the pressure head can be checked with a tensiometer or pressure transducer. 5.5 Ventilated drying oven set at (103 2) C. 5.6 Analytical balance with a scale interval of 0,1 g. 5.7 Shallow vessel, spoon or scoop a

46、pproximately 50 ml capacity. 6 Preparation Prepare the laboratory sample in accordance with 8.4 of EN 13040:2007. 7 Procedure 7.1 Moistening, saturating and equilibration at 50 cm water (5 kPa) pressure head 7.1.1 Fill at least 2 tubes (see 5.2) with the test portion taking care to prevent artificia

47、l air voids. Cover each tube with synthetic gauze (see 5.1.2.3) secured with an elastic band. Place the tube on the grid in a dry water bath (see 5.3). 7.1.2 Slowly, with constant flow, fill the bath with water until the level reaches to within 1 cm below the top of the tube. Filling should take app

48、roximately 30 min. 7.1.3 If a tube shows signs of floating, place a weighted disc on the top of the tube allowing air to evacuate and at the same time ensuring that compaction of the sample does not take place, (see Figure A.4). 7.1.4 Allow to stand maintaining a constant water level until the sample is thoroughly wetted (up to 36 h). 7.1.5 Remove the tubes and without delay, transfer the tubes t
