In the context of aggregate testing, a sieve with which size is noted for use?

• A. #20, #30, and #100
• B. #10, #16, and #200
• C. #5, #25, and #125
• D. #50, #75, and #200

Answer: (B)

The choice indicating #10, #16, and #200 sieves is noted for use in aggregate testing because these sieve sizes are commonly utilized to assess the particle size distribution of coarse and fine aggregates. In aggregate testing, a sieve analysis is a crucial process to determine the grading of aggregates, which is essential for ensuring the quality and performance of construction materials.

Sieve #10 has a significant opening size that allows the evaluation of larger particle sizes, while #16 and #200 are used to analyze finer materials. The #200 sieve, in particular, is important for determining the amount of material that is considered fine enough for various applications, including concrete and asphalt mixtures. This information helps in meeting specific engineering requirements and enhancing the overall durability and performance of construction projects.

Using these specified sieve sizes enables contractors and engineers to adhere to industry standards and ensures that the aggregates used in construction meet the required specifications for performance, thus contributing to the safety and longevity of the structures being built.
