In geotechnical engineering, soil compaction is the process in which stress applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation , not compaction, has ...
Compaction may refer to: Soil compaction, for mechanically induced compaction near the ground surface; Compaction of ceramic powders; Compaction (geology), part of the process of lithification involving mechanical dewatering of a sediment by progressive loading under several km of geomaterial; Faecal compaction, an extreme form of constipation
Lithification (from the Ancient Greek word lithos meaning 'rock' and the Latin-derived suffix -ific) is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock.
Heavy compaction can impede plant growth. soil conditioner - any composted or non-composted material of organic origin that is produced or distributed for adding to soils, it includes 'soil amendment', 'soil additive', 'soil improver' and similar materials, but excludes polymers that do not biodegrade, such as plastics, rubbers, and coatings.
The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...
The changes that occur during this diagenetic phase mainly relate to the reworking of the sediments. Compaction and grain repacking, bioturbation, as well as mineralogical changes all occur at varying degrees. [3] Due to the shallow depths, sediments undergo only minor compaction and grain rearrangement during this stage.

Since the nature of cleavage is dependent on scale, slaty cleavage is defined as having 0.01 mm or less of space occurring between layers. [1] Slaty cleavage often occurs after diagenesis and is the first cleavage feature to form after deformation begins.
