What does the term 'sieve analysis' refer to?

Sieve analysis refers to a laboratory technique used to evaluate the particle size distribution of a granular material, such as aggregates. This process involves passing the material through a series of sieves with different mesh sizes, allowing for the separation of particles based on their size. The amount of material retained on each sieve is then weighed and used to calculate the percentage of the total sample that falls within each size range. This information is crucial for understanding how the aggregates will behave in various applications, such as in concrete or as base materials in construction.

Determining particle shapes, evaluating strength characteristics, and assessing liquid limits are related to aggregate testing but do not specifically describe sieve analysis. Particle shape analysis focuses on the geometric characteristics of the particles, while strength evaluation involves testing the ability of the aggregate to withstand loads. Liquid limit tests evaluate the water content at which soil changes from a plastic to a liquid state, which is unrelated to particle size classification. Therefore, the focus of sieve analysis on particle size distribution is what makes it distinctive and essential in aggregate testing.
