Here’s a list of common sand laboratory equipment used in geotechnical, civil engineering, and soil mechanics labs for testing and analyzing sand properties:
1. Sieve Shaker & Sieves
– Used for particle size distribution analysis (gradation test).
– Includes a set of standard sieves (e.g., ASTM or ISO mesh sizes).
2. Sand Cone Apparatus
– Measures field density and compaction of sandy soils.
– Consists of a metal cone, jar, and base plate.

3. Relative Density Apparatus
– Determines the maximum and minimum density of sand.
– Includes a mold, funnel, and vibratory table.
4. Permeability Test Setup (Constant/Falling Head)
– Measures the hydraulic conductivity (permeability) of sand.
– Includes a permeameter cell, manometer tubes, and water reservoir.
5. Direct Shear Test Apparatus
– Evaluates the shear strength of sand under different normal stresses.
– Consists of a shear box, loading frame, and dial gauges.

6. Triaxial Test System
– Advanced testing for sand’s stress-strain behavior under confined pressure.
– Includes cell pressure system, load frame, and data acquisition.
7. Proctor Compaction Mold (Modified/Light)
– Determines the optimum moisture content (OMC) and maximum dry density (MDD) for compaction.
8. California Bearing Ratio (CBR) Test Setup
– Assesses the load-bearing capacity of compacted sand for pavement design.
9. Sand Equivalent Test Kit
– Measures the proportion of clay/silt fines in sand (for construction quality).
10. Hydrometer Analysis Set
– Used alongside sieving to analyze fine particles in sandy soils (<75µm).
11. Atterberg Limits Devices (for Silty Sands)
– Determines liquid limit & plastic limit if sand contains fines.
12. Oven & Moisture Content Equipment
– For drying sand samples to determine water content.
