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...

Permeability of Soils

Permeability of Soils Permeability of a soils is the rate at which water flows through it under the action of (unit) hydraulic gradient. The passage of moisture through the interspaces or pores of the soil is called “percolation”. Soils porous enough for percolation to occur ...

Angle of Internal Friction of Soils

Angle of Internal Friction of Soils The resistance in sliding of grain particles of a soil mass depends upon the angle of internal friction. It is usually considered that the value of the angle of internal friction is almost independent of the normal pressure but varies with the ...

Internal Friction of Soils

Internal Friction of Soils Internal friction of soils is due to the resistance of grains to sliding over each other and is the characteristic of the coarse materials of particle-size larger than about 0.002 mm. The magnitude of the internal friction of a granular mass depends on ...

Cohesion of Soils

Cohesion of Soils Cohesion of soils is the internal molecular attraction which resists the rupture or shear of a material. Cohesion is derived in fine grained soils from the water films which bind together the individual particles in the soil mass. Cohesion of soils is the charac...
