## Grading of aggregates | Types of aggregate | Significance

Natural aggregates are round, flaky, and platy in shape Similarly, an artificial aggregate is obtained by crushing the parent rock They are mostly angular in shape Besides, artificial aggregates can be made by fly ash also Aggregates are mostly used in the construction industry It holds about 6070% part in normal concrete Aggregate in concrete should chemically stable or inert

## A Detailed Guide on Grading of Aggregates

Grading of aggregates is determining the average grain size of the aggregates before they are used in construction This is applied to both coarse and fine aggregates The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up On dividing this sum by 100, The Fineness Modulus of that aggregate is determined This helps in
