Methods of testing soils for engineering purposes, Method 5.3.2: Soil compaction and density tests - Determination of the field density of a soil - Sand replacement method using a sand pouring can, with or without a volume displacerdoi:AS 1289.5.3.2-2004...
Moreover, the greater the range of density and water content covered by the test points, the more accurate the soil model will be. 4. After the soil model is made, EDG can be used for field test. The test area is an area with the same physical characteris...

The experimental results of soil compaction in laboratory and field were obtained. It is found that the test results in laboratory agree with that obtained... J Zhang 被引量: 18发表: 1995年 Physicochemical Properties of Reclaimed Soil with Weathered Coal in Open Cast Mining Areas of Loess Plate...
field (hectares). However, most research on prevention of soil compaction with some mechanical basis does not go beyond the size of a soil profile. This is because usually only the wheel rut is considered. Seismic methods could provide the basis for assessing vulnerability of soil compaction at...
Bulk density designated the weight of dry soil in a given soil volume, accounting for both the solid part and pore spaces of soil, and reflected soil compaction. Content of coarse fragments corresponded to the mineral particles not passing a 2-mm sieve and reflected soil texture29. ISO ...
Upon loading various green nanosilica contents, our results show an improvement in the key parameters including Atterberg’s limits, maximum dry density, optimum water content, and shear strength of treated soil. Under optimal loading condition, the nanosilica-mediated soil analyses reveal a significant...

The flushing chemical was applied to the bounded experimental field, followed by addition of agricultural water, creating a soil-solution ratio of 1:1.5–1:2. The soil suspension was mixed by a tilling machine until it turned into slurry. It is important to mix the soil suspension thoroughly ...
The cumulative pore volume, pore size distribution, and pore volume percentage were obtained by processing and analyzing the test data. An SU8100 series Hitachi high-tech ultra-high-resolution field emission scanning electron microscope24 was used for the SEM tests. First, the consolidated samples ...
