The Compaction is normally achieved through the input of energy into the soil by impact, kneading, vibration or static means. It should not be confused with consolidation, in which water is "squeezed out" under the action of a continuous static load.

∙ 13y agosoil consists of voids ....in voids there will be air and water.......removal of air from voids is compaction..and removal of water is consolidation

∙ 14y agoconsolidation is when you bunch things together like your debts for instance whereas compaction is when you tamp down sand or dirt as an example hope this answers your question

What does mechanical stabilization of a soil accomplish?
improve the drainage or compaction characteristics of soil
Who was the inventor of consolidation test?
The Classical Method of soil testing for consolidation was developed by Karl Terzaghi. Consolidation occurs when a pressure is applied to a soil whereby water is squeezed out but the space is not replaced by air.
Compressibility of soil- geotechnical engineering?
The compressibility of soils is a process known as consolidation. Consolidation is the geotechnical process of reducing a soils volume by reducing voids either filled with air or water. The are different forms of consolidation, however consolidation and settlement are indeed problems that a Geotechnical Engineer would address.
What is the difference between engineering soil and other soil?
Engineering soil is when ground is prepared(engineered) for an specific purpose. Soil is dirty or ground naturally found on earth.By Oscar Venegas "Ozkhar"
What is consolidation optimum moisture content and maximum dry density?
Consolidation:Consolidation is the process where pore water pressures dissipate from a fine grained low permeability soil over time which has a load applied to it and is free to drain (the drained condition is soil mechanics).As the material is of low permeability, as load is applied and the pore water pressures cannot dissipate, they increase in a proportional manner to the load and so resist deformation. As the water slowly escapes from the soil pore spaces however, the pore pressure reduces and the soil skeleton can deform as the pore water in the pore spaces is no longer holding the pores open. Once the pore pressures have completely dissipated (which may take tens of years in very low permeability clays), the pore spaces will have totally closed and the soil has undergone consolidation. This can result in significant deformation and is something that must be taken into account during geotechnical design.Optimum Moisture Content and Maximum Dry DensityThese terms relate to compaction of soils. This is a process where a load is applied to the soil to "squash out" the air in the pore spaces. This acts to decrease the soils volume and so increase it's density (which has the added benefit of increasing the soil's shear strength).Moisture content is a way of describing the amount of water in a soil and is defined in a number of differing ways.The degree of saturation is used to describe the ratio of volume of water (VW) in the soil compared to the volume of available pore space (VV).Sw = VW / VVAs can be seen from the equation ,if the pore spaces are totally filled with water then the volume of water equals the volume of void or pore space and the degree of saturation is 1 (100 % saturated).As per the consolidation process above, if the moisture content is too high, when you apply a load to a soil, the pore pressures prevent the soil from being compacted as they hold the pore spaces open. As the moisture content decreases the soil becomes more easily deformed (less stiff), however once you decrease the moisture content beyond a certain limit you are increasing the total stress within the soil which in clays acts to increase the shear strength making them more difficult to compact and in courser soils leads to the formation of soil suction (negative pore water pressures) which also acts to increase the soil strength making the process of compaction more difficult.As such the optimum moisture content is that at which compaction is easiest for a given soil, which then produces the highest (or maximum) density. This is termed the dry density as it is measured based on the change in mass of a soil sample after the water is removed by drying of the sample.
How do you read soil compaction test probe?
what are the needs for soil compaction and the factors affecting it ?
What is consolidation and settlement when referring to soil?
Consolidation and settlement of soil refers to decreasing the volume of soil by replacing water with air. The formula for soil consolidation can be found on the Wikipedia website.
What is a soil compaction test?
Bearing capacity of soil
What is degree of compaction of soil?
Compaction is the process by which loose soils are applied to a construction site and densified. The objective of compaction is to remove air voids from the soil. The degree of compaction of a soil is expressed in terms of its dry density ρ d or dry unit weight γ d (These measure grain packing.)
How can soil compaction affect a plants growth?
Soil compaction affects plant growth because if the soil is more compact it is harder for air, sunlight, and water to get to the roots of the plant.
Would compaction damage soil structure?
There are alot of layers for damaged soil.
What does mechanical stabilization of a soil accomplish?
improve the drainage or compaction characteristics of soil
Where does happen compaction?
Compaction in the broad civil engineering sense is usually meant to mean the increasing of the density of a material by applying compactive effort and removing the air present, i.e. decreasing air voids content.Good compaction is not difficult.You first need a material that is in a suitable condition to be compacted, you lay it in the correct layer thickness, and you use compaction plant capable of compacting that thickness.A variety of rollers both in size, weight and type are available to compact soil, granular and bituminous materials, and a number of hand operated devices are available for compaction in confined spaces such as trenches and haunch widenings.By far the most common cause of poor compaction is attempting to compact too thick a layer of material at a time.It is necessary to have the correct combination of roller compactive effort related to the thickness of material laid for successful compaction to occur.The importance of the correct compaction of materials cannot be stressed too highly, and you will find reference to appropriate compaction procedures in many British Standards, DOT Specifications and DOT Design Manuals, Specification for the Reinstatement of Openings in the Highway, and other publications.Soil compaction will depend upon the nature of the soil and its moisture content.The soil can be a cohesive clay, sand and gravel, or more likely some combination of clay and granular material, e.g. boulder clay, which is what makes soil engineering so interesting.But if you have a soil, or granular material, that has cohesive properties, (i.e. exhibit plasticity), to whatever degree, moisture content becomes very important.Too wet you will have consolidation problems at a later date, too dry and full compaction will be hard to achieve, and further compaction/consolidation will happen at a later date as equilibrium moisture content is established.
