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...

Plasticity Index of Soil

Plasticity Index of Soil (PI) It is the numerical difference between the liquid limit and the plastic limit of a soil and indicates the magnitude of the range of the moisture contents over which the soil is in a plastic condition as defined by the tests. The liquid and plastic li...

Plastic Limit of Soil

Plastic Limit of Soil The plastic limit signifies the percentage of moisture at which the soil changes, with decreasing wetness, from a plastic to a semi-solid state, or with increasing wetness, from the semisolid to the plastic state. It is the lower limit of the plastic state. ...

Liquid Limit of Soil

Liquid Limit of Soil Liquid Limit is the minimum amount of water required to be added to a soil, expressed as a percentage of the dry weight of the soil, that will just make it to flow like a liquid when jarred slightly. At the Liquid Limit, soils have very small shear strength w...

Plasticity of Soils

Plasticity of Soils Plasticity is the property of a soil to undergo large deformations when stressed, without cracking or crumbling, Plasticity is a major characteristics of all cohesion soils and is due to the lubricating effect of the water films between adjacent particles. Inf...

Specific Gravity of Soil

Specific Gravity of Soil The specific gravity of soil particles is defined as the ratio of their density to that of water. The specific gravity of soil particles may vary from 2.0 to 3.3, but usually is between 2.65 and 2.75. The usual soil weight (voidless) is between 2600 and 2...

Density of Soils

Density of Soils The density or true weight of a soil is equal to the specific gravity of the solid materials x 1000 (weight or density of water per Cu. m). A soil consists of solids, pores or voids and the moisture. The overall weight of the mass (including solid particles and t...

Compressibility of Soils

Compressibility of Soils Gravels, sands and silts are incompressible, i.e., if a moist mass of these materials is subjected to compression, they suffer no significant volume change. Clays are compressible, i.e., if a moist mass of clay is subjected to compression, moisture and or...

Elasticity of Soil

Elasticity of Soil A soil is said to be elastic when it suffers a reduction in volume (or is changed in shape and bulk) while the load is applied, but recovers its initial volume immediately the load is removed. The most important characteristic of the elastic behaviour of soil i...
