    Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)
