Is the moisture content below which there is no change in the volume of the soil?
The moisture content of a soil below which the soil volume becomes constant is called the Shrinkage limit. Explanation: The Shrinkage limit is the amount of water content within the soil just enough to fill all the pores of the soil. At this point, the soil is saturated.
What is shrinkage limit water content?
Shrinkage limit is defined as the maximum water content at which any further reduction in water content will not cause a decrease in the volume of soil mass. It can be defined as the water content at which the soil changes from the semi-solid state to solid state.
Why volume of soil does not change if it is allowed to dry beyond shrinkage limit?
Soil contains mineral matter, organic matter, water and air. For any fixed volume of soil, the amount of air present in soil varies according to the water content. Therefore decreasing the water content of a soil below the shrinkage limit will increase the air content but soil volume will remain the same.
Is soil not fully consolidated under the existing overburden pressure is called?
Explanation: According to Soil Mechanics, the soil, which is not fully consolidated under the existing overburden pressure is called under-consolidated soil.
What is the shrinkage limit of clay soil?
Shrinkage limits ranged from 14.3 to 41.1\% for remoulded samples and from 7.7 to 30.9\% for undisturbed samples. Volumetric strains (dependent on initial water content, w0) ranged from 2 to 23\% for undisturbed samples and from 18 to 52\% for remoulded samples.
How does moisture content affect soil?
The soil moisture content of soil is the quantity of water it contains. In soil science, hydrology and agricultural sciences, water content has an important role for groundwater recharge, agriculture and soil chemistry. If the moisture content of a soil is optimum for plant growth, plants can readily absorb soil water.
What does high shrinkage limit mean?
What Does Shrinkage Limit (SL) Mean? Shrinkage limit (SL) is the moisture content at which a fine-grained soil does not change the volume on drying; the moisture loss is compensated by air that enters its pores. It can be determined in a laboratory using a disturbed or undisturbed soil sample.
Which of the following does not happen when compaction is done *?
Which of the following does not happen when compaction is done? Explanation: On compaction of a soil mass, the shear strength is increased.
When a soil whose present effective overburden pressure is the maximum pressure that it was subjected to in the past then it is?
consolidated
1. Normally consolidated(정규압밀), whose present effective overburden pressure is the maximum pressure that the soil has been subjected to in the past.
What is shrinkage limit of soil?
Shrinkage Limit of Soil (SL) Shrinkage limit is the limiting moisture content, expressed as a percentage of the dry weight of the soil, at which a further reduction in the moisture (by evaporation) will not cause any further decrease in the volume of the soil mass but at which an increase in the moisture content will cause an increase in…
How does evaporation of water cause shrinkage in soil?
Evaporation of water causes shrinkage in a soil up to a certain degree beyond which decrease in volume does not occur ; at this stage the soil has reached its shrinkage limit.
What happens to the volume of soil at Stage 2?
In stage II, the soil is fully saturated, but a further decrease in the water content does not cause any decrease in the volume of the soil and air occupies the space of the evaporated water. The volume of the soil at shrinkage limit is equal to the total volume of oven-dried soil.
What is the volumetric water content of soil?
The volumetric water content is the ratio of the volume of water to the unit volume of soil. Volumetric water content can be expressed as ratio, percentage or depth of water per depth of soil (assuming a unit surface area), such as inches of water per foot of soil.
