Category: Aggregate – Gradation / Particle Size

Methods in this category evaluate the particle size distribution and grading characteristics of aggregate materials used in concrete, asphalt, masonry, and other construction applications. Gradation testing determines the proportion of particles within specified size ranges and verifies compliance with project specifications and applicable standards. These methods are essential for assessing aggregate suitability, controlling mix design performance, and ensuring proper workability, strength development, and durability of construction materials.

Typical tests include sieve analysis, particle size distribution, and gradation verification procedures.
