degree of compaction การใช้

• The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction.
• The weight that is used, depends on the degree of compaction desired and is between 8 tonne to 36 tonne.
• Fill placement work often has specifications requiring a specific degree of compaction, or alternatively, specific properties of the compacted soil.
• To ensure adequate soil compaction is achieved, project specifications will indicate the required soil density or degree of compaction that must be achieved.
• The degree of compaction depends on the weight of the hammer, the height from which the hammer is dropped, and the spacing of the locations at which the hammer is dropped.
• On day 4, embryos were scored in function of their degree of compaction and blastocysts were evaluated according to the quality of the throphectoderm and inner cell mass, and their degree of expansion.
• Soil bulk density, pore-size distribution, water permeability and the relative apparent gas diffusion coefficient give a good overview of the permeability of soils to air and water and therefore on the degree of compaction.
• The particle density is a relatively well-defined quantity, as it is not dependent on the degree of compaction of the solid, whereas the bulk density has different values depending on whether it is measured in the freely settled or compacted state ( tap density ).
