Test: Clay Material & Soil Structure- 2

Both illite and montmorillonite are made up of sheet like unit.

Thickness of montmorillonite, T = 7 × 10^-10mm
T = 7 Å.

Soil structure is an important factor which influences many soil properties such as permeability, compressibility, and shear strength.

Single grained structure is usually found in coarse-grained soil.

Soil structure is defined as the arrangement and state of aggregation of soil particle in a soil mass.

An arrangement composed of ‘flocs’ of soil particle is known as flocculent structure. As the particles are oriented ‘edge-to-edge’ (or) ‘edge-to-face’ with respect to one another.

In dispersed structure of particle are oriented face to face with one another in a dispersed state.

An arrangement of coarse grains forming a skeleton and matrix represent composite soils.

Honey comb structure is composed of loosely arranged bundle of particle. Hence they have comparatively less stable structure than others.
