Classification of Aggregates as per Size and Shape -Coarse …
Coarse aggregate; Fine Aggregate When the aggregate is sieved through a 4.75mm sieve, the aggregate passed through it called fine aggregate. Natural sand is generally used as fine aggregate, silt and clay also come under this category. The soft deposit consisting of sand, silt, and clay is termed as loam.
