📘 Relative Density of Soil

• A Fundamental Concept in Soil Mechanics

• Understanding Relative Density of Soil is essential for analyzing the compactness, strength, and settlement behavior of cohesionless soils such as sand. This lecture explains the concept using dry unit weight relationships, laboratory procedures, and practical engineering significance.

🔍 Key Topics Covered:

✔ Concept of Relative Density (Dr)

✔ γd(max), γd(min) & γd(field) method

✔ Rod Compaction Procedure

✔ Data sheet & calculation technique

✔ Engineering applications in foundation and earthwork design
