Granular soil is a type of coarse-grained soil made up primarily of gravel, sand, or silt, containing little or no clay. It is distinct from cohesive soils like clay.
Based on the provided reference, here are the key characteristics of granular soil:
Characteristics of Granular Soil
- Composition: It means gravel, sand, or silt, which are considered coarse grained soil.
- Clay Content: Granular soil has little or no clay content.
- Cohesive Strength: It has no cohesive strength.
- Behavior When Moist: Granular soil cannot be molded when moist. However, some moist granular soils may exhibit apparent cohesion.
- Behavior When Dry: When dry, it crumbles easily.
Essentially, granular soil is defined by its larger particle size compared to fine-grained soils and its lack of the sticky, moldable quality that clay provides. Its properties are dominated by the friction and interlocking between individual particles.
