These tests are useful for:

• Soil classification
• Geotechnical investigations
• Foundation studies
• Road construction
• Soil behavior analysis

6. Soil Hydrometer

A Soil Hydrometer is used for sedimentation analysis of fine-grained soil particles.

Hydrometer analysis can help determine the distribution of fine particles in soil, particularly the silt and clay fraction. ASTM’s soil and aggregate testing programs include sedimentation/hydrometer analysis as part of commonly used soil testing methods.

RTCDHAKA supplies soil hydrometers for laboratory applications, including models referenced to ASTM hydrometer specifications.

7. Soil Sieve Analysis Equipment

Sieve analysis is used to determine the particle-size distribution of soil and granular materials.

A typical soil sieve analysis setup may include:

• Test sieves
