Which sieve size are the aggregates initially placed into for analysis?

• A. 2 inches
• B. 4 inches
• C. 6 inches
• D. 8 inches

Answer: (B)

The initial sieve size commonly used for the analysis of aggregates is 4 inches. This sieve size is typically employed in practice for the preliminary separation of larger aggregates before they undergo more detailed analysis through smaller sieve sizes. Using the 4-inch sieve allows for an effective initial classification of the aggregates, separating out larger particles that may not be suitable for certain construction applications. Once the larger particles are removed, finer sieves can be used to provide a more granular classification of the materials. The other sieve sizes mentioned can also be relevant in different contexts or standards, but the 4-inch sieve is standard for this initial stage of aggregate analysis in many construction and engineering practices.
