Explanation:

Composite soil structure:

  • Based on the relative proportion of fine-grained particles and coarse-grained particles,

This structure can be divided into two types :

Cohesive Matrix

  • In this case, clay content is more as compared to coarse-grained particles as a result of which bulky particles are not capable to have particle-by-particle contact.

Coarse Grain Skeleton

  • In this case, the empty spaces in single-grained structures which are termed voids are filled with clay particles.

Additional InformationThere are five types of soil structures:

  • Honeycomb Structure
  • Single-Grained Structure
  • Flocculent Structure
  • Dispersed Structure
  • Composite Soil Structure
