Granular material either natural/processed from deposits of sand, gravel or rock. Normally sized as coarse aggregate or fine aggregate. Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate.
