Specification of Fine Aggregate/Coarse Sand
Fine Aggregate Fine aggregate/ coarse sand consists of natural sand, crushed stone sand or crushed gravel stone dust. It should be hard, durable chemically inert, clean and free from organic matter, not containing any appreciable amount of clay balls or pellets and other harmful impurities i. e. alkaline, salt, mica, decayed vegetation, lumps etc.

Fine Aggregate an overview | ScienceDirect Topics
Fine aggregates with angular particles ('sharp sand') are suitable for the fine aggregate fraction of concrete or road aggregate (see 131). 'Silver sand' is sand with a very low iron content that is favoured for the manufacture of highquality optical glass.

Fineness Modulus of Coarse Aggregates and its Calculation
Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.
