What is the minimum sample weight required for fine aggregates after drying?

• A. 200 g
• B. 300 g
• C. 400 g
• D. 500 g

Answer: (B)

For the determination of fine aggregates after drying, the minimum sample weight specified is 300 grams. This weight is essential to ensure that the sample is representative and provides reliable results when conducting tests such as specific gravity or moisture content assessment. Having a sample that meets this minimum weight helps reduce the variability and ensures that the test conducted on the fine aggregates is accurately reflective of their properties.

Lighter samples may not provide a sufficient amount of material to yield meaningful or consistent results during testing, as variations and potential errors can skew the data significantly. Thus, setting a minimum weight requirement helps maintain the integrity and reliability of aggregate testing processes.
