What does the gradation/sieve analysis test determine?

• A. The types of aggregates used
• B. The sizes of the aggregates/particle size
• C. The moisture content of the aggregates
• D. The origin of the aggregates

Answer: (B)

The gradation or sieve analysis test is specifically designed to determine the sizes of aggregates or particle size distribution within a sample. By using a series of sieves with progressively smaller openings, the test measures the amount of material that passes through each sieve. This information is vital for understanding the particle size distribution within a sample, which impacts the material's performance in various applications such as concrete, asphalt, or other composite materials. A well-graded aggregate can improve the density and strength of a final product and reduce the need for additional materials. Recognizing the particle size distribution helps engineers and material scientists assess the suitability of aggregates for their intended use, ensuring quality and performance in construction and engineering projects.
