This size of sand is mostly used for masonry works. Pit sand is mostly coarse in nature. Fine Sand:-Sand passing through the 1.5875 mm sieve is called fine sand. Fine sand is mostly used in plastering works for better finish. Classification based on grain size:-Classification of Aggregates: Grain Size, Density, Shape,Classification of aggregates based on: Grain Size. If you separate aggregates by size, there are two overriding categories: Fine; Coarse; The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and
