Standard Soil Analysis Sieves

In soil testing laboratories, sieves are used to separate and classify soil particles based on size. This is done through sieve analysis, a fundamental test in geotechnical engineering that helps determine soil gradation for construction suitability. Commonly Used Sieves: Coarse Sieves: 75 mm, 63 mm, 37.5 mm, 19 mm, 4.75 mm Used for gravel and coarse sand separation Fine Sieves: 2.36 mm, 1.18 mm, 600 μm, 425 μm, 300 μm, 150 μm, 75 μm Used to identify fine sand and silt particles Key Features: Precision-made mesh for accurate grading Stainless steel or brass construction Compliant with ASTM, BS, or IS standards Typically used with a mechanical or manual sieve shaker Sieving plays a vital role in understanding soil behavior, ensuring proper material selection and design in civil engineering projects.
