What is the required amount of material passing a 2.00mm (No. 10) sieve for sandy soils in particle size analysis?

In particle size analysis, the required amount of material passing a 2.00 mm (No. 10) sieve for sandy soils is essential for obtaining accurate and reliable results. For sandy soils, the standard practice calls for a sample size that ensures sufficient material is available to conduct various tests effectively. The correct amount is 110 grams.

This amount is significant because it helps in providing a representative sample that can yield accurate measurements of particle size distribution, crucial for evaluating the soil's suitability for construction and engineering projects. Having an adequate sample size allows for more precise readings and reduces the margin of error when classifying the soil type, which is vital for effective material testing and analysis.

Smaller amounts of material, such as 25 g or even 50 g and 60 g, may not adequately represent the broader particle size distribution within the sample, potentially leading to misleading results and interpretations. Hence, ensuring that 110 grams of sandy soil is analyzed allows for comprehensive testing aligned with industry standards.
