Which of the following parameters is NOT typically evaluated in sieve analysis of aggregates?

In the context of sieve analysis of aggregates, the primary focus is on determining the distribution of particle sizes within the material. This analysis helps assess how well the aggregate will perform in concrete mixtures, ensuring that the right proportions of coarse and fine materials are present.

Particle size is a fundamental parameter since it directly influences the grading of the aggregate, which is crucial for achieving desired workability and strength in concrete. Grading compliance assesses whether the aggregate meets specific standards or specifications required for a particular application, making it an essential part of the sieve analysis process.

Fine material content is also an important measurement since it determines how much smaller material is present in the aggregate blend. Too much fine material can negatively impact the concrete’s workability and strength.

On the other hand, while particle shape is important in evaluating the overall performance of aggregates in concrete, it is not a parameter typically determined during sieve analysis. Sieve analysis focuses solely on size distribution rather than the shape characteristics of the particles. Therefore, this parameter does not form part of the standard sieve analysis process.
