20、uctionThe particle density (s) is used together with the dry bulk density (bs,see ISO 11272) for the calculation of the pore volume of a soil layer.1 ScopeThis International Standard describes two methods for the determination of particle density of soils calculated from the mass and the volume of s
21、oil particles.The first method (4.1) is applicable to fine soil ( 2 mm diameter).The particle density may be used for the calculation of the proportion of solids and of the porosity of soil layers in combination with the procedure given in ISO 11272.2 Normative referencesThe following standards cont

The frame serves as a platform for a weighing dish with a small container so that both frame and dish can be immersed in a large container of water during weighing (see Figure 1).4.2.1.2 Vacuum desiccator with self-indicating desiccant.4.2.1.3 Thermometer.4.2.2 Density d

Clean the gravel and stones (for example by shaking them with sodium hexametaphosphate solution), wash in water, and dry them at (105 2) C.Place the gravel and stones in the small container of the dish and weigh them (ms). Then fill the small
29、container with distilled, boiled and cooled water. Put this container in a vacuum desiccator and de-aerate twice for 10 min, allowing air to enter the desiccator between evacuations. Then put this container on the weighing dish and submerge dish with the container in a large container containing dis
30、tilled, boiled and cooled water and carefully reweigh while the stones and gravel are suspended in the water (msw). Remove and discard the sample, clean the weighing dish with its container, and weigh it while it is submerged in water (mw). Measure the temperature of the water, and from Table 1, det
