For fine aggregate samples, which sieve is the sample REQUIRED to pass through?

For fine aggregate samples, they must pass through a specific sieve size to ensure uniformity in particle size and effective performance in construction applications. The requirement for passing through the 3/8" sieve ensures that the aggregate consists of finer materials that can be utilized in creating concrete and other mixes. This sieve size is critical as it helps create the desired consistency in the aggregate blend, allowing for better compaction, reduced voids, and improved bonding with cement.

Using coarser aggregates, such as those that would not pass through the 3/8" sieve, could lead to performance issues, such as inadequate workability or increased void content in the final product. Therefore, passing through the 3/8" sieve is a standard procedure that is in line with the definitions set forth in construction specifications and standards for fine aggregates.
