Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.
