What is Aggregates

In the Fine Aggregates, the grain-size lies between 4.In other words, these pass-through from sieve with the mesh size of 4.75 mm and are retained on a sieve of 0.Sand is the most universally available natural Fine Aggregate.

1 Some contract documents specify certain aggregate sizes for specific uses or may suggest one or more of these sizes as appropriate for the preparation of various end-product mixtures.In some cases, closer limits on variability of the aggregate grading are required.

What are the metal aggregate sizes

The most common physical limitation on the maximum nominal aggregate size in concrete is the gaps between steel reinforcing bars.The aggregates must be small enough to pass easily through and around the gaps in the steel reinforcement during compaction to avoid any voids around bars or honeycombing at the edges of the concrete.
