Fine Aggregates or Sand : When the particles of granular material are so fine that they pass through a mm test sieve, it is called fine aggregate. Usually, natural river sand is used as a fine aggregate in concrete. In places where natural river sand is not available, the finely crushed stone may be used as fine aggregates.
