4. Inter-Relations

Soil properties and their inter-relationships play a crucial role in geotechnical engineering, affecting subsequent tests and analysis. Accurate measurement of water content and unit weight upon laboratory receipt are fundamental due to potential changes during transportation. The chapter details calculations for dry and moist unit weights, void ratios, and specific gravities, all essential for understanding the physical state of soils.
